Pt-40 conversion help please
 

I have a Great Planes Pt-40 I'm converting to electric. I already have the motor mounted just trying to sort out the ESC connection to the rx.

I'm trying to do this on the cheap without buying all new radio and rx both of which are Futaba circa 1989. My big question is regarding the new ESC and wether or not it will power the servos. The original setup has a small battery plugged into the rx that powers the servos. Do you guys know if the new ESC will be able to send power to the servos?

The rx is a Futaba FP-R114H and the ESC is a 60A Classic from RC electric parts. Com.

Thanks in advance for the help

if thats an old AM radio I am not sure its safe to use any more? I think the frequency was real wide ..and would pick up interference easy..I started in the 90's, and I think all my original radios from then are obsolete...


I think there are some decent cheap radios out there now...

The radio is a Futaba Attack 4. Frequency listed is 72.670 MHz

If the radio is a narrow band, it will have a gold sticker on the back. To answer your initial question, plug the ESC into the throttle port on the receiver then plug a servo into any other slot. Connect a battery to the ESC without hooking up the motor. With the transmitter on, the servo should function. That would mean the the ESC has a BEC feature that powers the receiver and servos off the motor battery.
