ok, just to make sure I'm doing everything properly. These are the steps I followed from the link posted above...

remove the red programming bridge (little red jumper near the battery leads). While you are there, you should also remove the black BEC jumper if you are using a receiver pack or UBEC as recommended. This black tab is near the red jumper, but tucked under the heatshrink. Remove this to disable the BEC and utilize the receiver pack/UBEC.
Now plug in the receiver pack/UBEC and the main batteries and wait. After 5 seconds, you will here a beep from the motor. When you here this beep, move the throttle to full power and wait. after another 5 seconds, you will here another beep. When you here this, move your throttle control to full reverse and wait. After 5 seconds, you will here a double beep, indicating that set up is complete. Now replace the red programming jumper and turn off/unplug your main batteries and receiver pack.

So this is what I've done...

step 1 - I remove the red jumper that is sticking out in the first picture I've attached as well as the black one that is located beside it.
step 2 - I plug the batteries in
step 3 - after the motor beeps I go full throttle until the motor beeps again then I move to full reverse until the motor does a double beep.
step 4 - I put the red jumper and the black jumper back on
step 5 - I unplug the batteries.

I've tried moving the receiver as far away as I can from the thing that is wrapped in white at the front of the truck (which I guess is the ubec?), but the wires will only allow me to move it so far and it doesn't seem to make a difference.

Am I missing something or doing something incorrect when setting it up?
