Piccoboard and Rx

The Piccoboard is an amazing device containing the throttle / tail-rotor mixer, BEC,  two speed controllers, and piezo gyro all in one small package. 

The Piccoboard. Pots are for tail gyro sensitivity and throttle-to-tail-rotor mix.

The Piccoboard is usually supplied with a 4-function Rx on a second PC board. The two boards come stuck together with double sided tape and wrapped in heatshrink to form a complete unit. 

The receiver is a 4-channel unit. Two of the receiver outputs go directly to the speed control inputs of the Piccoboard via short flying leads. The other two outputs are connected to the the pitch and roll servos.
