Hi,

I just made the plunge and bought a Futaba 9C radio for use with my Ikarus Eco V2 heli.
Im running with the piccoboard plus and have noticed some strange behavior with the tail motor since switching to the
Futaba 9C.

First off, I noticed from the start that the tail motor would seem to want to race just as fast as the main motor when
applying throttle. The rudder trim pot on the picooboard had already been adjusted properly for my old 4 channel radio
but with the 9C radio it seemed totally wrong. I decided not to mess with that and instead have gone the route of trying to program a custome revo mix setting for different throttle rates and then i'm fine tuning that with a bit of rudder trim.

My question is - Am i going about this all wrong?

My first thought was that perhaps the revo mixing on the the 9C was screwing with what the piccoboard wants to do by itself in mainting the proper speed mix between the main rotor and tail rotor. I tried turning it off but their seems to be only two options in the 9C revo mixing menu - "INH" and "ON" (**** is INH anyway?). So the next thing i tried was setting the revo mix for all throttle points to 0% and thought "yeh, let the picoboard handle it". Nope, no luck. The tail motor would just race like mad as soon as any throttle was applied at all.

If anyone could throw me some advice and perhaps an answer to these questions that would be great! I am using the SWH1 model setting as a base for my model on the Futaba 9C.

1) Do i need a custom revo mix (since the preset one isnt right for my model)
2) What does "INH" mean?
3) Is there some way to turn off all revo mixing on the radio and let the picoboard just do what it did before with the old 4 CH radio?

Thanks for the help!
