I need some setting for my Velos from anyone here flying one . I thought it was set up right and when I spooled it up the Heli spun counterclockwise, so rudder no holding .
Question how much counter torque on tail blades should I have on 3 Blade set up
Rotation speed rate
How much revomix
Anything that can help , to scared now to spool it up .

Hello,

you do not need anything special for Velos except swashplate type CCPM 90 Velos.

No revomix is also needed for nearly any helicopter.

Regarding rudder it is same for all models.
It must compensate in the right direction - so that tail slider is behaving as attached to the bench while moving with tail.

Settings from someone else might not work correctly at all, because each servo might require different reversing.

But you can verify correct operation always before flying to be perfectly sure it will fly.
