WL Toys V202 microquad - DEVO8S

FMOD1 DR=80% EXP=0% for indoor.
FMOD2 DR=94% EXP=0% for outdoor(can't filp)
FMOD3 DR=100% EXP=0% for flip
DR>=95% , it can flip,I set FMOD2 DR=94% you can get max. travel and
it would NOT filp even you move stick to max. position!
GEAR(CH5) swith for light ON/OFF.
RUDD travel set to 150% for max. rudder speed.(but it still slow! )

Rudder 150% does not make sense - the protocol limited by one byte precision, that is 100% is the total maximum. What I can (and plan, given time) to do is to play with trims a bit. Every packet has trims for rudder, elevator, and ailerons, which is now set to neutral. It should add some, but not much to its pirouette ability. I would not expect much, though. Better use Mini Pet propellers as advised by MassiveOverkill. V202 guidance is designed with stability in mind and fast rudder is very risky for quads stability - you basically turn off two counter-posed propeller and lose control over axis, perpendicular to their. It will result in wobble, which is observable in V939 and some other models.

Hi Victzh,
Thanks for your explanation about rudder travel setting ~~

I'm using the 7E, but mine doesn't flip at 100% rates unless I flip the HOLD switch.

I also made the rudder at 100% for all FMOD settings.
