Futaba 3vc problem again

[Carole_MH]

Having finally got my 3vc to accept the fasst module I have now encountered another problem which is also present on 40fm with the module and PCM receiver.
The problem now is that the throttle works fine but when I use the steering the brakes are applied when steering right but when steering left the speedo goes into reverse. This does not happen when I use the car with my 3pks only with the 3vc but on both 40fm and 2.4
Any help much appreciated.
