Anybody had a problem with the throttle servo on a 4pm radio ?
I just got the radio maybe 2 months ago added a R203 GF receiver .the servo will turn on cycle 2,3 times shuts off turn switch off and then on and it works for the same amount of time, need alittle help.
Thanks Chris

What servo are you using? Analog or digital?
What receiver battery voltage are you running?
Do you have your radio set to a digital or analog servo?

If any servo in the bunch is analog, you have to run in the "NORMAL" analog modulation type setting on the transmitter. It will smoke the servo if your not careful.

Do you have another receiver to test?

I think I might have found my problem. Low battery? That's my fault.
