I recently aquired a parallel port interface wich came with the PPJoy windows xp driver...
I connected my Hitec Flash 5x to the pc and i noticed that every channel was working except channel 3 (throttle).... At first i thought it was missing but then i realised that channel 1 and channel 3 where moving together when i moved the channel 3 stick and the throttle stick did nothing... :S
Anyone knows why? Is it the timing ajustment? i noticed an earlier post of someone having the same problem with a futaba but never got a reply....
Hope someone can help...

thanks in advance...

This happened to me. One of my micro-switches for reversing the servos was set in the middle. I just moved it to the correct side and it moved a bit and stayed there. I had just used the TX a few hours before without this problem, so it remains a mystery as to how and when this switch got moved.

I have a Hitec Laser 4
