The lower vibration reading most likely from being mounted in the bottom of the frame I suspect.

If you have not bought batteries you may want to experiment with the 4000, 4400, and the 5000 packs. I find mine flies a bit sedate with the 5000's in, yet it pops real nice with the 4000's due to the lighter weight. If you run the heavier packs it flies obviously peppier with a higher head speed to liven things up. but get what works for you and feels best.

Exactly, they are the same in flight. The only advantage to to FS on an electric heli is isolation from the high vibe areas due to a separate sensor and the ability to have more ports for power inputs.

I expected it could be the wires or more likely the higher end sensor. Definitely seemed to coincide with blade turbulence. Hard to notice except in hard moves especially at higher RPM like 25-2700.

Have to disagree with you Ron. The full size has superior sensors made by Pinpoint. They have a higher resolution and quicker response. The benefits of being able to place the separate sensor where it receives less vibration, plus no servo wires to transmit vibes to the sensor make the full size a much better 3 axes gyro than the mini.

Hey BobOD, we agree again. What do you know? Sometimes engineers do agree when the answer is so obvious.

The sensors are different, higher end is a debate itself. Yes the isolation issue is true, which is why I mentioned it. As for flight characteristicsif someone gave you a VBAR Heli and said fly it, you could not tell if it were a full size or a mini.

I think that's a bad assumption! Yes, they use the same algorithm and much the same code. However, an electro-mechanical device relies on more than just programing. The full size's superior resistance to vibration give it a more controlled feel, particularly when doing violent maneuvers that produce a high degree of vibration in the airframe. Certain models may not exhibit this, but others do.

Models like the Logo 700 and Whiplash are very solidly built. They can be highly loaded and not push the airframe much. I can say for certain that on some models, I can tell there's difference between the mini and full size. You can also see it in the logged V-Bar data.

Whether your average RC heli pilot can, who knows? I'm sure if I pointed out the characteristics of the loss of tight control at these certain high vibration/airframe loading points in their flying they would notice it.

Yeah, I do need to say that I do fly solid, vibe free helis and it has never been an issue.

Hey BobOD, we agree again.
ACK! PTHTHTHTHTTT!

I think blade turbulence is what makes it most noticeable. Amount of coning of the main blades maybe also. Great for stable flying, not so for tracking through the hard stuff.

Heck, I certainly would not pay the extra money to avoid having to use a y-harness. Nor a couple of resistors for an RPM sensor (although I prefer to use a resistor and 3.3v zener diode for better precision). That kind of stuff just comes too easy for me.

An advanced, precision, modern sensor...priceless.

Good points. Mikado is due for a complete redesign on the mini. I read that it was in the works. Oh yeah, you don't need the resistor or resistor/diode combo if you keep RX power to 5V or less. The Y harness is another story.

I'm saying a simple y-harness would not be reason enough to spend more for a full size. An improved sensor would....a very simple y-harness would not. For me anyway.

Have you finished and flown it.?
I'm loving mine. For some reason I think I feel more relaxed flying it compared to my 600. Have tweaked some things and this Heli is super super fun. It'll pretty much do anything you want it to. Flew it in fairly high wind today and it flew fantastic. The gusts blew it about a little, but the vbar kept it in line, pretty amazing Heli - great job mikado

I just sold my last full size. All minis now. Worth it for the small size and cleaner wiring. As mentioned... Can't tell diff in flight.

Same here all mini!!! With the full sized v-bar you run a greater risk of damaging the Sensor wire on the lower tray in a crash. Have you ever seen what a logo frame looks like after a crash??? mini v-bar on the top tray is a win win!!!!

Good info on the mini. Can you run it with 2 Spektrum satellite receivers as well? I'll likely try one later on.

No, haven't built it yet since I'm still acquiring electronics for it, plus I was at a local funfly yesterday and will be working OT today . But so far I have received the V-bar unit, 2 Spektrum satellites, a BLS251 tail servo, 3 BLS451's (2 out of 3 not shown, but have arrived at my complex's main office), a digital pitch gauge and a 15t pinion that Ron/laughingstill generously donated for this project (thank you Ron!!). I'll also be running a 6S 4400mAh and a couple of 6S 5000 TP packs.

The last thing I need is a Jive 100 LV ESC w/heatsink, which I'm ready to order today , so I'm trying to find the best deal online. Usually Kontronik electronics are excluded from discounts so the next best thing is to look in the classifieds. I'll likely end up buying it new though if it's in stock. If I get the ESC this week, then I'll have it built next weekend for sure.

BTW, I'm thinking the 6S 5000's will perform best. What size 6S pack do you guys like running in yours?

I'm really impressed with my YGE it has bec and sensor built in. I like my lighter packs a bunch only draw back is near the end of the flight they don't have as much punch as the 5000's. It autos better with them. I don't use the idle in autos or bailout mode.

You are welcome
Yes you can use 2 satellites with the Mini, it was the first VBAR to actually have that capability.
6s 5000 packs are pretty much standard for the 500, they will serve you well. I used everything from Zippys (never again) to TP packs with good results.

ESC Arrived
Thanks guys, I'll likely end up selling my 6S 4400 pack then (after trying it in Logo) and replace it with another 6S 5000 from TP.

I ended up ordering the Jive 100 LV ESC last Sunday from Readyheli and received it today along with a heatsink, a second BEC cable and the ground kit.

Now to start building .

The build begins!
So I figured I should get a head start prior to the weekend now that everything is here.

I only have the frame halves and tail case built so far. It took some careful looking at the manual to make sure I didn't miss any parts installed within the frame (not that there were many parts to install though). Other than figuring out a way to get all the nylock nuts to slide into place, the frames went together rather quick. As far as the tail rotor, I removed some minor flashing from the ID of the plastic tail grips as Ron recommended.

I really like the futuristic look of the frames and the bright neon color and finish of the tail case. I can definitely tell Mikado has reduced its parts count in the tail case compared to the first CF cases they came out with for the Logo10/24 series.

I will get some more built tomorrow.

Bad BLS451?
Finished the rotor head, installed the boom, servos, landing gear and ESC (heatsink next). Then I realized I needed the Mikado servo arms. I received the servo arms this past Friday and so I was about to go straight into the Vbar programming, but that's when I ran into a potential issue with one of the new BLS451 servos . One of them makes an awkward gear noise towards the top of the travel as shown in the video below. Out of almost 30 BLS451 servos I've ordered so far, this is the 1st time I run into such a gear noise with new/uncrashed servos. Not willing to risk it in this new FBL bird so I will be looking to return it on Tuesday, for replacement, after talking to Hobby Services tomorrow. Have you guys run into similar gear noise with new BLS451 servos?

In the meantime I've been watching Mr. Mel's Vbar 101 videos and the ReadyHeli basic Vbar setup video and it doesn't look too hard to get it right. I did find out from those videos that I currently have the 3-axis gyro/sensor installed incorrectly (90 deg off). So I will fix that.
