Comments: I have to retract my statement above about these being compatible with 9650/9257 cases. The top cap is almost, but not exactly the same and if you put a 9257 top cap on it it will cause drag on the gear train. The middle section of the case is also designed differently because of the magnet attached to the output shaft.

Application(s): Helicopter cyclic.

Comments: Case and gears are compatible with the 9257/9650 There is a slight bit of tolerance in the recess for the top ball bearing that allows the output shaft to rock back and forth about 0.3mm however this isn't enough to cause problems with flight performance. They work well as cyclics in a flybarless 500 size helicopter and can handle high gyro gain without causing "the shakes". Uses a hall effect sensor chip on the board and a magnet on the output shaft instead of a pot. The output shaft does not have (or need) a stop.
