ok.
i wanted to coordinate rudder and aileron
Though your Tx can't mix aileron and rudder, (or give differential aileron throws),
there are two easy alternatives for getting coordinated turns:
1. Manually by using both rudder and aileron
2. Setting up the aileron linkages in such a way that the 'up' movement is noticeably more than the 'down'
With equal up/down throws, you get adverse yaw. When you roll left, the nose wants to yaw right. This is because the 'down' aileron side producing more drag than the 'up' aileron side. The usual cure for this is differential throws, ie, more up than down. With enough differential, you can get the 'up' aileron side to have more drag than the 'down' aileron side, in effect getting yaw in the same direction as the roll.
The correct way however is to set up the differential so that there is no yaw either way, and use rudder to coordinate.
(My Tiger Moth has so much adverse yaw, especially at low speed, that if i use only aileron to turn left, she actually turns to the right. Took me by surprise initially!)
