Hello !

I em a quite new in the flybarless sistems.

Hear is my plan: I have ordered the electronic AC-3X ( german )

I plan to convert my Trex 450 on flybarless with Futaba S3153 servos on ciclic.

So hear is the problem : I must convert the head of my rexy on flybarless.

My question is : what is the transmition ratio betwen the inner bals on the swash plate and the bals on the rotor grips ( it seems to bee about 1,3 or something like that )

I plan to make a new grips with the longer arms and without the mixing linkages.

I don't have the numbers you are looking for, but the way I handled the situation was to move the servo arm balls to the inner most hole (required remounting the servos) so I could achieve very close to similar ratio between the servo and grips without the need for mixer arms or major modifications.
