Yeah, I've already been in touch with my LHS.
Assuming its $1.50 to £1.00, I'm going to be about $180 for parts, against $250 for a new kit. All the servos are ok as is the Rx. I'll have to bench test the motor, but it appears ok.
I'll maybe get this one going again, but it'll take a few hours.......
