Scale Helis

Hello,

can you provide me with the scale or XXL software: I have 2 VBAR Pros :
Serial numbers are
1410043780
1410800468

I haven't set-up these helis with VBARs yet but please find below the détails :
I would appreciate any settings you can provide

Heli 1 :

Vario Lama Turbine, 19.5 kg; 2M50 Long; 3 blade main rotor with blades of 1050mm; RMP of rotor head is 850; 3 blade tail rotor with 18 cm rotors; the main rotor head has no damping, it is quite rigid but allows the blades to love up and down a little; pitch for main blades is -2 degrees to +10 degrees. At mid stick on the transmitter, I have 5 degrees. The Gyro will be on Heading Hold.

Heli 2 :

Kamov Coaxial Turbine Heli; 25 KG; 2M20 Long, 2 times 3 blade rotor head with blades of 1050MM; RPM of rotor head is 875; the main rotor Heads have very hard damping. Pitch is 0 degrees to +10 degrees: at mid stick in the transmitter I have 5 degrees. The gyro works in normal mode (not Heading Hold). The gyro changes the pitch on the upper rotor via the spider on top of the rotor Head. For this to work, when you apply rudder in the transmitter you also via programming change the overall pitch to compensate for the increases / decreased pitch on the upper rotor; the gyro also controls the tail rudder (like in a plane). if there is an autorotation, the gyro changes to 0% gain.

One question - to be sure:

Have you tried a Vbar on a trainer already - and are familar with the setups and procedures?

I ask this because some guys want to try on a scaler first which won't be helpful for the general things.

Hello,

I only fly scale helicopters (!) I have used over the years many different types of flybarless units. The Lama turbine has flown five years on a different system but I wasn't happy with the tail.. I have an older version of Vbar in an older scale heli. I have no concern with setting these up but I have no experience around specific adjustments that are specific to Vbar for large scale helps.
For example,
- Main Rotor Style, Agility, Gyro Gain, Elevator precompensation, Paddle simulation
- Tail Rotor RC Deadband, Acceleration, P Gain, I Gain, Stop Gain A and B, I decay (if I use normal mode) control loop, Torque Precompensation.

Thank you

+1 for you ;-)

here my scale recommendations - i used the XXTReme Firm on the BO 105. Keep in mind i am flying +-12 deg collective and a cyclic setup which gives you a good response ;-) - a usual scale guy would set up 60 as agility and 30-35 as optimizers.

RV,
Have you tried negative paddle sim?

No - but AFAIK Andy Rummer added some of this (i think -20 or -30) at his 2.5m Tiger. It will soften the reaction a bit on the cyclic.

But - as it isn't officially - be careful and keep a "zero paddle sim" bank in the background during tests.

I asked about negative paddle sim because I have tried it for an F3c setup. You are correct. It gets very "heavy" with any setting over -30. But, it does help when sensible values are used.
