Graupner HVS939BBMG with Futaba - Help!
 

Hi,
I have a plane with new Graupner HVS 939 BB MG servos and a Futaba R7014SB (FASSTest) receiver and a Futaba T16SZ Transmitter.
These just seems like not working together, my elevator servo lives it's own life and is running up and down etc....

My own theory is that FASSTest is way too fast for those servos and I need and receiver with another protocol but I'm not an expert, I have tried FASST mode on the receiver but It says the same as FASSTest ... Any suggestion on what to do?
Can there be something wrong with that one servo on the elevator?

I need at least a 12 channels receiver.

Thanks in advance,
Hans

I got it, there is something wrong with that one servo on the elevator.... even if it's new. just need a new one, that's to figure out! :-)
