Man, I can't believe I'm missing my QJ8 this much.....

I'm flying little T right now..... And it's hard to learn new trick on this one. I could easily get disoriented. With my 8, once I get warmed up, I get rouge about doing the tricks I've been practicing on the sims.

I got to get my 8 back on air again. Just a few more time. I should be able to figure out how am I gonna reinvent my set up. One last push on the V2 SP's capability before I switch to EX........

twinring

You might be refering to me. The skid braces are that of JR .30 sized Venture CP, I cut off the middle portion. The actual skids from .30 Raptor. The only thing I hate about it is that it needs constant rebending back. It squats when landing a tiny bit hard. I'm trying to figure out how to re-enforce it. I used a 2mm aluminium sheet to attach it to the frame. I tried the 2 piece canopy on it, although still needs some painting, looking at the front, it resembles the Aurora.

The washout arm, that's another design flaw on SP. The swash side of the lever is narrower, when in reciprocating motion it supposed to work harder to leverage the flybar side. And the screws that attaches it to the washout block is too thin, I noticed that this screws are bended when I disassembled it.

Sorry for the mixup boomstrike,

AFAIK the upgrade part is the same mixing arm as on the EX.

The mixing arm is fine. And the upgrade for it is simply for increasing pitch throw, at the same time, it also increases cyclic pitch range. I noticed that when I moded mine when I couldn't get 5* cyclic pitch in stock configuration, even if the lower side of the swash was already rubbing on the main shaft. The upgrade does double folded benefit.

It's the control lever that's located on the washout block that is flawed, and actually had a failure on mine during flight.

@ Tail_BoomStrike


i took some time and read the full theread now
is it really such a good mod what you done on page one here ?
I jusy wonder is this is the reason the control lever broke ?
Just a thoguht but when you extend it by 4mm the forces on this will be massivly increased ....
meaning it will push down and pull up when flying and the lever you created now 4mm cannot cope with the forces ? ...of course then it could break ..

the forces are amplified mutltiple times now with 4mm spacer?
but I might be compeltely worng

Before I got down to actually modifying the head there already exist a binding on mechanism on the Hiller system, that manifest itself when applying cyclic while at negative pitch.



The way I found out is that whenever I finish a build I always make it a point to bench test the set up with the main blades off, run the rotor head at max 50% throttle in idle up mode, apply full negative and full positive collective along with that full cyclics in all directions.

I didn't do the mod until the fourth month of flying it when I believe metal weakening already took its toll. The mod did the trick in ridding the binding. Look at how the EX version is redesigned. The mod frees up the Hiller system giving the heli a powerful cyclic response without having to rely on longer flybar, which have a drawback, and ultra huge paddles which are designed to track air further away from the center of the rotorhead......

I see the bit about allignment but I have yet to see any binding on my 8 ?

I do the same as you, well maybee a bit less power i run it just as much so it keeps turning and do the same test cyclic on all pitch angles on the bench ...
I fail to see any binding ????
Where in the negative section does it bind?
All i moan about is the allignment and the apparent waste of "directness"because of the links not beeing straight
But i dont see any binding
I have a LONGER 149mm eco8 modified mainmmast so maybee thats why i fail to see binding ?

I don't know about you, but I have good result on mine.

I am an aerobatic flyer, and and the mod did a lot for me. I never went as far as using longer blades which to my opinion is also too much for the mini servo to handle, nor have yet switched to powerful motor. Niether did I switch to the lighter carbon fiber frame only to add more weight on my rig......

Peace

Iwould try it but i dont understand what for ?
if I could see the binding i d probably be straight onto it but even at -10 and moving (stiring the cyclic ) i dont see binding
maybee you can explain that bit to me a bit more ?
maybee iam looking wrong ...

Hs85 MG (my cyclic servos) are more then strong enough to handle 463 blades I wouldnt worry about that one

OK, got my 8 back together. Just had a test flight yesterday. So I flew a couple of set of packs. Well, I didn't rechecked the pitch throw and it turned out there's more + than - pitch. But, since I didn't have my tools with me, I just kept on flying it. I could still manage it but I was limited on the tricks I could do. Like I can't tic toc, there's not enough collective to bounce it back from inverted. But it flew very well, I could still single piro flip, just can't do double. Axial roll was very tamed.

On the rebuild though I re-tweaked my modification. All that's added was a .5mm thick washer on the spacer between the seesaw and the flybar control arm. So instead of 1.5mm spaced, it is now spaced 2mm. Doing that, I could maximize the cyclic tilt of the swashplate, no binding.

Let me just make it clear, the mod is not for sport flyer, putzing or figure 8'ers, where the stock setup is more than enough stability wise. I'm simply logging what had been useful to me, and what I think might be useful to others but I'm not forcing anyone to do the same. It is their option to try it or not to try. I did the mod trying to make my 8 match my 450Tr's agility without getting too expensive, which was very surprising for me, since now I got stability and agility on my 8 that I was seeking. After all this is a hobby.

So don't be bugging me saying, "Why? I'll try, but it doesn't make sense. Or don't understand what 'ya saying Dude. My HS-85MG more than strong enough to handle 463mm blades". At least post a video of what you can do with your heli, and then talked about the component you used, or mod you did that helped your heli to preform the stunt........

Im using HS81MG servos on my cyclic, with 440mm blades and they are more than strong enough..

So, that explains the number of servoes in your collection that wouldn't center you reported one time. Mine had gear replacement several time and still centers just fine

And where is the CC45HV in this picture that you showed me before?
http://www.runryder.com/helicopter/...ight=jimboflies



Looks more like Airmaster 65 that I have on mine.

Anyway, this afternoon I just tested a new motor I ordered. Not the Z motor I posted sometime ago, but seems capable of 3000rpm. Lighter than the Z, so the AUW on my 3s, 3lbs 6oz or 1.53087424875 grams. Tad bit overweight, not by a much. But I'm guessing the power will be similar to A30 8XL. But don't qoute me on that, since, I never had comparison test run between the two. And I'm still on the test stage on the one I got right now. And I might need to get me a watt meter, cause I'm not sure how much current it's drawing, but it's pretty powerful I could tell. On a freshly charged set of packs, it would tach 2700rpm on 80% throttle and blades at 0* pitch, it scared the heck out of me, I dialed the curve down to 88-75-88 throttle curve, with -10/0/+10 on the pitch, 0* pitch would tach 2400rpm wich is my target HS, moving to 1/4 stick that would lower the pitch to approx. -5* blade pitch while on the ground, tach reads 2500rpm.

But my numbers are not conclusive. It was a shady day, and the tach meter is suppose to be only accurate on ideal daylight. Still I could tell enough this motor won't bog with my stock woodies. I'm just not sure if my battery could handle it, that I do intend to get me a watt meter. The flight is solid the first 5 min and flyable up to 8min, but at 17mph wind during my test flight with lots of gust, I have to reiterate none of these numbers are conclusive. I hope I could post another video. I might be able to. Soon.

The busted servos are from crashes, not failure. That picture is not even my heli, I just used it for demonstration..Here is a PIC of my heli!!Oh yeah ,the HV45amp got crashed and I sent it in for repair.this has my HV85amp on it..and the Z20(550plus Century), 440mm blades.

Yet, you did anounce that it was the mod you did on yours. Where are you getting all this pictures. I'm all confused with the inconsistencies of your reports. Bad crashes or mild crashes, mine does center well. Piro flips and aileron tic toc capable. Although I didn't have real bad crash. Your servo cases were probably being over strained.
