Flybarless Rotor Head Systems > logo vbar system hows it fly?

i would like to know how a flybar versus flybarless sytem flies (from people who have actually flown the vbar system on the logo) i specifically want to know any details including additional things u can do, bad tendencies...etc

also, how detailed in the vbar setup they went, was there lots of frustration trying to get the right settings, etc. thinking of a logo 600 3d, danny j's setup (which he posted). that thing looks really powerful and fast, just how i like it

Logo 600 3D
go one step further and get the actro 32-3, 19t pinion
CC110 esc, gov mode
JR 8717 servos, run em on direct lipo 2 cells 1300mAh or likewise
V bar unit, V bar head
Regulator for the RX, 5.5 volts
600 V blade TST mains, 105mm V tails

the V-Bar really opens a whole new level when it comes to heli flying. Power is really improved, so is the agility. the roll/pitch rate is infinitly adjustable by changing your ATVs, like you would on the piro rate.

There are however 2 small dissadvantages. One: in an auto, with a slow head speed, its not the most stable, basically you gotta land with the blades still going, dont try drag it out. Two: crack rolls dont quite "crack" as much as with a flybar. It works, but you dont get the crack responce.

Other than that, it is so much better than a fly bar, if set up correct.

To top that all off, it is by far the best tail gyro i have used, piro rate is very constant no matter what you do, and the hold is perfect too. it is far better than the GY611.

Jason,
I've been flying a Logo 10 with V-Bar and I would say it flies extremely nice. It is stable yet offers very fast cyclic rates, very predictable and consistent, "on-rails", and generally feels like a larger heli than it is.

Initial setup is not that difficult at all and the "out-of-the-box" settings aren't too far off of a very nicely flying heli. After that it may take some tweaking to get it just right and really dialed in to your tastes. How much you tweak is really up to you.

Does the V-Bar support 140CCPM?

Yes.

With the pc adjustment software of VStabi it will be possible to set defaults for every kind of ccpm.

You can choose the angles and the distances free for every servo.

Have a look at the wiki here:

I have one comming for my Logo 500 It flys great with a flybar it should be off the hook without

i guess im just interested how much different the sytem flies than a conventional flybar heli. ive flown a csm 600 E which was very different for me. of course it wasn't very programmable and was extremely sensitive(not setup for me) but i do like the quick roll rate the efficiency.

i need danny j's setup but i dont know if its pilot that makes it fly so well or if the system really is good and the transition from normal to flybarless makes rollrate and such similar to the flybar helis.

its mostly the pilot that makes it fly that well Jason After seeing his latest video with a fly bar, he is just as insane

And, the way Danny flew at IRCHA proves V-Bar will indeed do 'crack' rolls.

I was standing next to him at IRCHA during one of the demos, and I have never seen a thumb-finger pilot switch flight modes during flight as much as he does. It is incredible, and is one of his techniques that makes him entirely different as a pilot. After seeing him do it, it makes perfect sense to change rates for certain moves.

how does the flybarless flight characteristics change from a flybared heli. does it still move in a similar fashion as the flybar head helicopters or does it display more of a HH gyro characteristics. ive flown a csm flybarless 600E and it was very different and alittle bit hard i guess you can say. of course it was not setup for my preference. but i am scared the vbar system will feel the same way, however i see danny j run his so im more reassured, but just want to know for sure for sure if its not insanely sensitive and feels more of conventional helis in the market with of course the additional available cyclic and the efficiency. sorry to be so picky.

Jason,
I would not say flying a V-Bar setup is so different than a well setup flybar heli that it would take more than a flight or two to feel completely comfortable. One thing it might do is cause you to re-examine some of your inputs to take out corrections you've been making for a flybar heli that are no longer required on the V-Bar setup. The V-Bar setup causes more pure and accurate responses from the heli based on your inputs.

Yes, the CSM and V-Bar setups do cause more of a HH type response in that your inputs are more of a rate command than just a blade deflection angle command. But both systems are also 100% tweakable to how YOU want the heli to fly.

thanks for the reply, i wish for more to chime in as well as its great information.

i have been downloading lots of flybarless videos of the logo. i notice it flies very similar to a flybarheli. very smooth and doesn't make huge transitions like when i flew the flybarless 600. i thought danny j was just super talented and was able to fly the logos very well flybar and no flybar.

it does get taking used to i guess.

Jason,

Sorry my flybarless 600 was overly sensitive for you. I guess I got use to it. When I started flying my stock Trex600N more, I notice the different between the two more and more. I have tone down the sensitivity and it is flying a lot better now. I was also having some noise issues with the cyclic gyros which I also have resolved. It is super smooth now!

But last weekend I crashed it Bad! in a dumb thumb auto. Head straight to the ground nose in... smoked my so called "indestructible" A123 pack and G10 frame. You can give a another run after I rebuild it.

It's hard to say because the V-Stabi software allows you to completely customize the response and feel to how YOU want it to fly. If you want it to stop harder or softer from a roll, add in some collective "bounce" (gain on collective movement to amplify collective pop), switchable flight modes that allow you to change everything with a flip of a switch... It's just so different. It's impossible to fly it once to decide whether it's for you or not, you have to really spend some time with it and let it soak in.

I'd say in comparison, flybarless will feel more crisp, more direct, and more accurate. Also less affected by wind since the flybar interprets ANY wind as motion. You will also notice substantially improved power at high pitch angles due to the lack of flybar drag. The whole "feel" thing is entirely customizable. It's very different, since the only adjustments you'll use on the radio are D/R and expo. The rest is set up as standard single servo because all adjustments are done via software from a laptop or Bluetooth PDA.
