I just bought a used 3PKS with the FASST system installed and I am having a problem with getting the steering servo to work. It will not turn at all. I am sure the receiver works OK cuz I tried it on my B4 with a different servo and it worked fine. I also brought over the working servo from my B4 to my T4 and it works fine. Here is a list of the electronics I am running in the T4.

Radio: Futaba 3PKS
Spectrum Module: PK-FSM2.4G
Receiver: R603FS
Servo: Hitec HS-645MG
ESC: LRP AI Reverse Brushless (I don't think the ESC has anything to do with it cuz the other servo worked from my B4)

I have tried PPM, PCM and HRS modes.

PPM seems to be the only Modulation that works with this ESC.

My B4 has a GTB and an Airtronics 94357 servo(this is the one that works). My buggy will work in HRS mode.

Any ideas? I would hate to shell out $80 for a servo to find out I should have tried xxx, ya know?

Please help. I go racing tomorrow.

Did you check the connections on the servo plug ?
