First off, I'm completely new to the RC world. I inherited a 1986 Blackfoot that I'm trying to restore with new electronics. It has the original motor, which still works, but the speed controller doesn't work very well, so I wanted to upgrade. Here's what I have:
- Futaba T3PRKA 2.4G Transmitter (new)
- Futaba R203GF Receiver (new - came with the transmitter)
- QuicRun 1060 Brushed ESC (new)
- Futaba servos that came with the truck (old)
- New battery with Tamiya plug (Ni-MH battery)

1) Charge you battery
2) Connect battery to ESC and confirm it lights up when turned on... set jumpers to NiMh mode
3) Connect ESC to Rx on Ch2
4) Connect Servo to Rx on Ch1
5) Confirm steering controls servo, make sure trim is zeroed out on the throttle for ESC to calibrate
6) unplug/swap out servo with known good servo if ESC works but not the servo
If you accidentally reversed the polarity at any time, then chances are you fried the ESC and it will need to be replaced.

it does help to get the correct info.. this esc has no dip switches it has jumpers.. to set lipo or nimh mode
esc can not be blown by having radio in wrong position..no way no how.

only thing i agree with is make sure battery nimh is charged

Thanks for all the replies. I'll work on all of this tonight to see if it corrects my problem.
Also, how do I know the polarity of the motor? There aren't any markings on the motor itself, just yellow and green wires (motor side) and yellow and blue on the ESC.

just to clarify, I meant the polarity from the battery to the ESC is what can't be reversed without risk of damaging the ESC... if you reverse the polarity from ESC to motor, it will simply change the direction that motor spins, that's no big deal, typically you can either reverse the direction on the radio or swap the wires between the ESC and motor to get it move in the direction you would like.

Update: I charged the battery and made the changes to where the wires were on the receiver and everything works. Not sure if it was the battery or how I had everything connected but everything works. Thanks for all the replies and help. Much appreciated. Now on to find the replacement parts I need to finish the build.
Another update: For some reason, when the battery is connected, and I turn off the transmitter while the ESC switch is on, the motor continues to run, but when I turn the transmitter back on, the motor stops. Any thoughts?

This is a cardinal rule, you should never turn off the Tx without first turning off the car... however, there should be "fail safe" setting in your user manual that came with the radio to help you set the "Rx" to zero out when then signal from the Tx is lost, but this should never be a feature to rely on.

Futaba has a pretty good reputation for keeping settings long term... but there are some brands of radios that intermittently lose their settings, seen folks get runaways because they relied on their "fail safe" settings, turned off their Tx and then watch their car go WOT into an innocent person with their back turned... ouch!
Probably wouldn't hurt to hold the car in the air and periodically check the "fail safe" is still properly configured by turning off the Tx to check. It could spell disaster if you ever drive your car out of range and lose signal only to watch your car drive off into the sunset... ha!
