Several people have indicated that they are interested in some relativity between 700 and 800 class helis. Here are some basic calculations regarding a comparison of 713mm and 813mm mains assuming 150mm head bolt to bolt and 12lbs vs 15lbs AUW:

Disc area:

pi*r^2:

pi*(.813+.075)^2=2.477^2
pi*(.713+.075)^2=1.951^2

2.477/1.951=27% greater disc area

Circumference:

2pi*r:

2*pi(.813+.075)=5.579
2*pi(.713+.075)=4.951

5.579/4.951=13% greater circumference

Mass:

15lbs/12lbs=25% greater mass

I don't know a basic calculation for lift but I know the relationship is not linear. Some element of the equation is exponential. All things being equal (ceteris paribus) the larger disc will generate significantly more lift than the difference in size. Hopefully someone else can pick it up from here.

Peace out, yo!

Never mind about LiFe packs. I just found some discharge curves that show LiFe cells in a death knell at 6v - meaning voltage drops sharply below 6v. They will hold voltage very well through 90% of their useful discharge cycle but then drop like a rock around 6v.

Too high voltage. It will shutdown or destroy the BEC.
Does this go for the A123 cells as well if running 6v on the Jive BEC? If it is only charged from the BEC it would seem unlikely to reach higher than 6v. Maybe the 2s 6.6v LiFe pack is discharged beyond a point where it is useful at 6v. Any feedback on this?
I'm confused with the DCUP, bought 2 to reduce the drops, with or without it, the volt drop is exactly the same!
How much does it drop? Is it negligible, or is it significant?

Are there any issues associated with running the Jive 120HV's bec at 6 volts? In other words, it's no less reliable at 6v than it is at 5.6v, right? I just want to make sure there is no compromise in switching from 5.6v to 6v.

Also, I'm leaning toward the dcup now. Any issues with that?

Thanks guys!

Buffer Pack for Jive BEC
Anybody here know anything about wiring up a buffer pack? The idea as I understand it is to add a small battery in-line with the BEC as a buffer for voltage highs and lows or failure. It would maintain it's charge through the BEC.

I'm considering adding one of these to my Jive for cheap insurance. Any recommendations about packs would be appreciated as well.

Thanks!

This hasn't come up for a while. Anybody care to comment on lipo performance over the past season?

Myself, I have roughly 70 cycles on four sets of 6s 30c 3300mAh Turnigy lipos that are still performing well in 12s configuration in a vbar logo 600. I also have some 6s Hyperion VX 4200's that are not quite broken in yet at 20 cycles. Too soon to say on those from personal experience.

Anybody else?

Bad Belt?
Hi guys!

My 600 is making some funny noises which I think are comming from the belt. It's kind of a variable fast to high speed warble sound. A very slight movement in the tail is just visible also. The symptom is not constant. It seemingly comes and goes. I tried several different belt tensions, checked the one-way for slippage, the Jive governor, vbar 5.0 logs, linkages, bearings etc. - no dice. THEN, I noticed the syptom durring an auto. That pretty much rules out all the electronics. The next step is to replace the auto drive gear and the belt.

Anybody else had any issues like this?

Thanks!

The control lever may have failed first. That could have put the blades at a severe angle which may have caused the grip to snap. I've had three inflight tail failures but none of them are dirtectly attributable to a disign flaw; a loose belt rode up over the tail pulley, pitch slider unthreaded and came apart, snapped a grip bolt after a bladestrike doing autos.

Pulling out all that stuff? What stuff? To my understanding you simply charge or discharge and select the graphs you want to view. I wasn't aware that graphing chargers were all that common. Which ones did you have?

Here's a list of available graphs:
  • Amps vs. Time
  • Cell Volts vs. Time
  • Fallback vs. Time
  • Fuel vs. Time
  • Internal Resistance vs. Time
  • Pack Capacity vs. Time
  • Pack Volts vs. Time
  • Cell Volts vs. Capacity

Okay, I get it. It's a graph, not a table. The info is on pg 56-57 in the PL8 manual - graphs on 55, fuel tables on 57. Once a week, should I be so inclined, I can take some graphs of a charge or discharge cycle and compare them with previous graphs. Better yet I can export this data to an Excel file for easier comparison.

Say what you will but, in my opinion, this is way too cool!

I suppose the change in internal resistance over time is the best indication of performance but I'd also like to chart the change in the charge curve over time.

I believe I can chart both with the CCS software. In fact I'm pretty sure I can chart these changes for individual cells.

I used a couple TP1010C/210V combos for about three years, two iCharger 1010B+'s for a year and two FMA PL8's w/MW 1500-24 ps charging 2x 6x 6s (12x 6s) for the last month or so. The PL8's are quite impressive. They do everything my other chargers have done and more, and they do it better. Higher discharge and balance discharge rates, better internal resistance monitoring, special modes that adjust charge rates automatically a cording to feed back from the lipos, etc. And then there's the software. I currently use crappy lipos so it's not as important. But when I do get around to upgrading to premium lipos I will create fuel tables so I can accurately chart performance over time.

I've flown both in fbl config. I prefer the way the Protos flies - especially when it comes to autos. If you want to get creative with autos cross the L400 off your list. The lack of a driven tail significantly limits what you can do as far as that goes. Obviously the power to weight ratio is going to fall in favor of the Protos also. My vbar 400 was pulling up to 2200 watts and my protos smokes it at 1800. It is, to Shawn's point, almost too light. But with vbar that is not an issue in my experience.

If Mikado made a scaled down version of the 500/600 frame for the 400, I would certainly give it a try as that could be a winner. But the L400 was in my opinion is just not all that special.

I was using a new Custom Heli cf tail and the bearings were secured. I believe that I simply had the belt too tight. I made the mistake of adjusting it on the bench and then taking it into the sun. It went from a double low A to a triple high C (think bass to soprano).

I secured some new bearings in there and I'm checking it at the field. I think that'll do it.

Thanks for the advice guys!

Hi guys!

I probably only got 30 - 40 flights on this shaft. I think it's odd that it didn't last any longer. I did have a similar experience with my Protos. It's possible that I've overtightened the belts on both.

Any ideas on what might have caused this?

Thanks!

The digital display is nice but it definately isn't keeping up with realtime data. The graph shows spikes in excess of 3000W on several occasions while the digidisplay only shows it once. I wonder if there's a way to get the display to hold peaks for a little longer.

Dead One-Way
This is a first for me. My auto rotation bearing took a crap today. I noticed tha it didn't have the punch it normally does. Then it started making funny noises. So I brought her over and landed like I normally do - t-hold from a few feet up. I droped really quickly. I noticed that the motor spun down with the main rotor so I checked it. Sure enough, first it was stuck and then it wouldn't grab. Whatever the deal is it won't be going in the air again. I was a little surprised but, it wasn't a big deal.

Just thought I'd share.

Belts behaving badly
The belt on my 600 is doing strange things.

The first thing I noticed was a strange sound. The best way I can describe it is "yeeibid yeeibid yeeibid yeeibid". This usually occurs on the ground during spool-down but, I have heard something similar in the air as well.

Today while testing it on the ground I noticed the belt seemingly attempting to skip off the front pulley - while making this "yeeibid yeeibid yeeibid" sound. The sound is syncronous with the belt riding up the retaining wall and then dropping back into the pulley. The pulley is dead centered with the idlers which are fully seated in the frame, and the tension is right.

My prognosis is that the belt is worn unevenly. It has a few flights on it, a couple hundred at least, but there are no missing teeth. I may have gone in with it but not recently. It ssems strange that the belt would spontaneously develop some odd behavior.

Anyone else experience this?

Danke!

Actually, I did just notice that this one had a wobble also. It was very subtle. The only way to spot it was while spinning up with the blades removed. I assumed it had been doing that since day one and that it wasn't a big deal. Guess I was wrong.

It depends on what headspeed you want, the condition of your lipos and your esc. If you want low to moderate headspeeds the 11t would probably be a beter choice. If you want moderate to high headspeeds the 12t may be better.

The difference in headspeed could be atributable to new packs (first three cycles). I didn't consider that. My bad. Also, my Jive is programmed to mode 4.

Thanks!

The 4035-500kv on 12s with 11t mod 1 will get you roughly 2250 at 80% on the Jive 80hv. That's what I'm getting.

400kv would allow you to run lower headspeeds more efficiently if you wanted to go with some longer blades, ets.

I am putting six pairs of fresh 6s Turnigy 3300's through their first charge cycle even as we speak. So far we're up to a combined total of 7600mAh at 25.2v in just over 20 minutes. These will spin 620's on my 12s vbar L600. I just switched from 10s to 12s to reduce the amp load on what I expect to be less resilient HK lipos. I'm hoping this will yield more cycle life thereby reducing overall operating cost. We'll see how that works out.

So that would be my vote, build a 12s 600. It will blow your mind!

The lower peak amp draw leads me to believe this motor might be more gentle on lipos. This could equate to longer cycle life. I'm wondering if it would make sense to push 620's on 12s with this motor over say, the 4035-500kv.

I keep a Trex around to scratch the need-to-tinker itch. There's no end to it with those. Actually, I have to say that I am quite pleased with my 700n. It's been prety solid. The 450pro is a tinker hole! All are vbarred, so they fly pretty damn well.

They are agile, powerful, precise and predictable.

I don't have to think to fly it (vbar 600). There is no aiming or steering, no correcting or compensating. It simply goes where I want it to go and does what I want it to do. It's the closest thing to a telekinetic connection I've experienced with an rc heli.

As stated, fly one.

Disc loading with a Logo 600 is significantly better than with a Trex 600. So the Logo will outperform the comperably equiped Trex by a good margin. However, you will not get the flight time or punch on 6s that you would get on 10 or 12s. On the upside, with a 6s setup you will get a lighter flying heli and lower operating cost. I would definately not consider 695+mm blades on 6s. More than 600mm would put too much strain on the lipos - in my opinion.

I would like to try a 6s L500SE with 600mm blades. I think it would be a very fun bird.

I've built, flown, crashed, and rebuilt both as well as the Logo 10 which is essentially a stretched 400. By the way, the 500 does NOT need to be stretched to run 550's. Just bolt'em on and go fly. Other than that, I would add that the 500 survives crashes better. The batteries cost a little more. And the 10 flies lighter. If you want a lighter flying 500, just stretch it to an SE and add 600mm blades.

I'd get the 500.

Consider your budget for batteries. If that's not an issue, I would go straight for the 600. You will definitely not regret it. If you want to experience the epitome of Mikado perfection, fly their flag ship - the vbar Logo 600. I've flown the 600, 500, 400, and 10. The 600 is my favorite.

If you just strip it you can turn it 90 degrees like I did (thank god) but that only works once lol.
I did that last time!

The Pyro does look interesting. I have been a big fan of Kontroniks stuff for a while but, I've already given them about $3k - no joke!

I've never used Hacker or Xera motors but I've heard good things about both. As stated, I've been very happy with Scorpion motors. They get hot and they are not the most efficient but, they make great power. I had to switch to the mod 1 main gear after stripping two of the .7's in flight. I never had that issue with any of the Tango motors. I am not complaining about that though!

I have an email in to Lucien. We'll have to see what happens.

Thanks for the info guys.

New motor for the L600?
I've been running a Scorpion 4035-560kv on 10s through a Jive 80HV for a couple years now, and it has worked very well. I've had to replace the shaft and bearings a couple times, but that's not a big deal. My only complaint is that the metal is relatively soft. I've stripped two of the mounting bolt holes. So, I need a new motor.

I'm happy enough with the Scorpion motor to just get another one but, I'm wondering if there isn't something else worth trying.

Any thoughts?

Thanks!

I had a DS610 fail in flight not long ago. The heli moved in a manner outside of my inputs, so I landed it. All servos seemed fine on the ground. They centered and moved normally. Then I checked them by hand. One had lost nearly all of its stall force. I could move it at will. I replaced it with a new DS610 and it flies fine now. But I've never had so much as a hickup from any of the 8717's I've used.

If I have the budget I will definately go with a quality JR or Futaba servo. One crash negates any savings you might have gained with a cheap servo. It's not worth it in my opinion.

I don't really see any benefit in running high headspeeds. Sure, it can be fun but, I run 2050 with 620's and it still performs better than any other heli I've ever flown. With vbar you can get the same performance of a flybarred heli at a lower headspeed by simply increasing your pitch. Cyclic is not at all dependant on headspeed. Comming from nitro, you'll be quite happy.

I'd opt for a little extra flight time at a lower headspeed.

I didn't use them on cyclic (8717's) but I did on the tail (BLS251). I don't think there's really anything to be gained by using the rubber bushings. My thought on the tail was that it's a little more precise and a little more sensitive than the cyclics.

What kills me about the whole Mikado canopy drama is the lost opportunity to promote the product by having a thousand different - dare I say cool looking Logos out there. I've probably had 10 logo canopies - most were factory. My favorite was a cheapo Fusuno.

Mikado makes a fine product. There is no denying that. But their paint schemes are anything but sexy. Evidently that's a word that has little value or meaning in the German lexicon.

Buy the vbar L400 w/electronics for $725, keep the head and vbar electronics, sell the airframe. Or, do what I did. Build it, fly it, sell it, then convert your 500.

Mini-vbar $475

You should be able to get $150 for the airframe.

Probably a good idea. Myself and fellow Freak were discussing centripetal force yesterday when we arived at the conclusion that area immediately around the root/grips/headblock is exposed to ginormous loads. This is a pretty extreme case but, just the same. Here's the post where my calculations were corrected upwards.

Me:

Trex 700 rotor diameter w/710mm blades = 1602mm, multiplied by pi (3.14159) = 5032.83, multiplied by 2500rpm = 12582075mm/min, divided by 60seconds = 209701.25mm/second, divided by 1000mm per meter = 209.70 meters per second, or 469 miles per hour

Velocity at tips = 209.70 meters per second, or 469 miles per hour.

What is really profound in this scenario is centripetal force. Radix 710's are 185g each, multiplied by 209.7m/s squared = 43.97kg m/s (1kg m/s = 1Newton), divided by the radius .801m = 54.9kg/s, or 120.78 pounds!!! Both sides! Hovering! Now add in the dynamic loads associated with throwing a 12 pound heli around doing stuff like tail slides or tictocs.

kegerator:

Hey Terrabit,

This is some great information and I started reviewing the math and the results are actually much scarier than you calculated. Just a mathematic error on calculating the centripetal force on the blades:

Fc = mrw^2 (centripetal foce)

m = mass of blade [kg]
r = distance from rotational center to center of mass of blade [m]
For the TREX 700N, this is 91 mm + 2/3 * 710 mm (assuming COG is at roughly 2/3 the length of the blade)
w = angular velocity of blade [rad/s]
At 2500 rpm, this is 2500 rpm * [1 min / 60 s] * [2*pi / 1 rev] = 261.7994 rad/s

In the case of the 90-size at 2500 rpm:

m = 0.185 kg
r = 0.564333 m
w = 261.7994 rad/s

So, Fc (AT ONE BLADE! ) = 0.185 kg * 0.564333m * (261.7994 rad/s) ^ 2

Fc = 7155.57 N = 1608.6 lbs <-- There is more than 3200 lbs of tension on the feathering shaft at this headspeed at 0 pitch!

Same calculations:
1950 rpm = 978.7 lbs
2200 rpm = 1245.7 lbs
2500 rpm = 1608.6 lbs

Make sure and check those feathering shaft bolts! It's no wonder it's easy to spin a blade off - one minor crack in the carbon around the root, and it's all over. I personally have never seen a blade fly off in mid-flight, but I've heard many stories of it happening.

That blows!

This is the first time this has come up in the Mikado forum. Of the five Logos I've built and flown, the only problem I've ever had was the tail pully. The belt chewed one of the side rails down and jumped off mid tictoc. I've built a few helis though, and I maintain them well. I really don't have mechanical failures. Oh well, fortunately the frames are pretty cheap.

Hang in there brother.

I've used both. Both are excellent. Never had any problems with either. The BLS251 uses a narrower pulse width, 760 vs 1520 which might allow for higher resolution. Both operate at 333Hz. I couldn't tell a difference. The 251 has a double insulated servo lead which is kinda nice.

The JR is red. The Futaba is gold. Both are pretty!

Dude! I'm the king of Wikistuff! Besides, I have a physics text book at my feet, and various academic resources at my disposal. I get it. I was mostly just being a smartas$. That is where my true tallents lay.

Alright KC, my physics professor failed at this so, maybe you can help me understand how angular velocity, tangential speed, radians factor into the various equations used to quantify cetripetal force.

We should get some coffee, crash some helis, and talk about it.

All things being equal, I still think you ought to have even wear on both inner races.

Okay, so that points me in a different direction. With that bit of information I suspect the races are not seating correctly - not perpendicular to the feathering shaft, or the end of the feathering shaft is not true. If it were simply a matter of being tight and the races were parallel you should see uniform wear around the race. Try replacing the affected grip and innards with one of your spares and be certain that the end of the feathering shaft is not out of square.

Like Nathan suggested, pull the bearing assebly into the affected gip with the bolt already tightened and thread locked to the shaft. And mark the all parts with a black sharpie so that you know which set is which the next time you disassemble it.

Peace!

Is the pitting on the inside or outside race, both, or all four? Is the pitting even around the race(s)?

Scott, I think what you're running into is an overly tight bearing. You wouldn't necessarily feel that in a new, freshly greased installation. I'd guess that something is creating a preload. Some part in the headblock, grips, shaft or bearings might be machined slightly off spec or the dampeners could be at fault.

The head and tail bearings are different from others in your heli in the sense that they rotate to whatever pitch you input from your radio and then return to the exact same location every time. That's why you'll tend to see the uniform pitting in the race.

Relatively speaking, ball bearing retainer rings are new. I think it was 30 years ago or so that they appeared in automobiles. Before that, all bearings were packed free. I was a bicycle mechanic for a Seattle messenger service in another life. In my relentless persuit of perfection (cough cough, uh OCD) I removed the rings and added bearings. It does make a difference - especially in the old-school bottom brackets, headsets, and hubs of messenger bikes who see an average of 30 to 50 miles and more each day in every kind of weather (mostly rain).

I routinely performed minor miracles on a fleet of over thirty bikes in some unconventional ways. Even so, my little shop still moved more parts annually than any other bicycle shop in the city.

Good times!

To answer your question, yes. It does increase performance - provided you do it correctly. Conversely, it increases the margin for error. The retainer ring is idiot proof. If you free pack you bearings you just have to make sure they're properly seated. Once they are in there they can't come out on their own.

Eggy,

Hard dampeners can be rough on thrust bearings. Are the races pitted or are they smoothe? Can't see through the grease. If the bearing surfaces are not degraded then they are useable. Just place them back in the retainer ring, pack them in fresh grease, and reinstall them.

Or if you really want to get tricky free pack them. The retainer ring is just there as a convenience. Remove the bearings from the ring and pack an extra ball in there. You should be able to get at least one more ball in without the ring, maybe two. This will effectively distribute the load to a larger surface area which should improve funtionality.

I just ordered an ICE50 Lite for my mini-vbar 450Pro. 22.5g! If you buy the hype on RR and HF the ICE series ESC's are poised to take some market from the big K. At less than half the price of a comperable Kontronik ESC, it's almost worth the gamble. However, I'm still not prepared to replace the Jive80hv on my vbar L600.

I'll keep yas posted on my findings.

Here's a bit of the back end.

It's worth noting that this mod only took about 30 seconds but, it did require a 12" by 3/8" drill bit.

Not that you should have any problems but, your heatsink will function more effectively if you replace the velcro straps with zipties.

Easier stil!
No doubt someone will read this in horror and think "that guys a moron!" But this is what I've done the last three times without a hitch. Seperate the can/shaft from the stator/coil. Place a sufficient deep well socket into the can, over the shaft so that it clears and carefully drive the shaft out with a small hammer and a 1/4" drive extension or suitable bolt or whatever. Do the same thing in reverse to assemble taking care to adjust out any slop between the snap-ring and the top bearing. Then threadlock and set the set screws.

Works like a charm!

Peace out!

You might have trouble getting 8s to work with that motor.

153t main gear/12t pinion=12.7drive ratio
1100kv*3.7v/cell*8cells=32560rpm
32560/12.7=2563headspeed

That's at a nominal voltage of 3.7volts per cell. Yours will be higher. And you really don't want to run a 12t pinion either. That would be prone to stripping. Something in the 800kv range would work better on 8s.
