Need help with Futaba 3PMX
 

I have built a Sworks BK1. I got the 3PMX so i didnt have a radio for every car. I got it figured out for my EP Cobra. But when i go thru the steps for the BK1, the throttle servo only reacts in brake and when it does it pulses. I have zeroed out all the settings a few times and started over thinking i forgot a step or miss adjusted one. But same thing happens. I have even changed servos and no change to the reaction. Any have this before or anything. Please tel me what im doing wrong.

Thank you.

noone?

Were both servos you tried the same type/brand and if so, what are they?

Savox 1256, 1258tg

Try the TX in PPM instead of HRS and then re-bind it so the RX picks up the mode change. Pulsing is often a symptom of a servo getting an output signal it doesn't like. If that doesn't fix it, I would try a new/fresh receiver pack. Savox servos are such power hogs that you never know what they will/won't do when they are not getting enough juice.

ill try that. thank you.
