my first radio system glitched like crazy
but now i have a 2pl and its better but
i dont get good acceleration , i do but not alot of power

but no motor , itll light up saying its working but

Sounds like you have a brush hanging up on the motor. Not sure about the light coming on when its off though. But its allways a good Idea to unplug the battery when you're done, I dont ever leave mine plugged in.

Brushed motors need lots of TLC! Espically a mod (13t). Every two or three runs you need to take out the motor and clean with motor spray or break cleaner real good. Then on top of that about ever 6 to 8 runs if you are lucky you need to take the arm out and cut the comm and change the brushes. You also need to make sure you are not over geared because then you are going to run hot and make matters worse.

If the brush hood isnt dirty It might of gotten bent a little. I'd pull the motor out and pull the springs off and see if the brushes move in ond out freely or not then go from there.

Do you have the caps on the motor? Do they look damaged?

Slap another motor in there to see if its the motor, or some other part of your system.

Is your battery insulated from the chassis in some way? If I remember the MF2 has a graphite chassis and can be conductive, may be causing some glitching at the receiver level because of it.

You can start remedying it like this as I usually start this way:

1. make sure the receiver wire is wrapped with something to insulate it from the chassis. Run it direct to the attenna tube if possible and not up and under in the chassis. I usually have mine about 1 inch up on the attenna tube.

2. run electrical tape along the sides of the chassis where the battery would sit.

3. Put a fresh cut on the comm of the motor and make sure the brushes still reach the comm and have tension on them from the springs. If your brushes as too short, you could be getting intermittent running from this.

4. Clean the brush hoods and make sure the brushes move freely.

Give it a test then.

If you still glitch, put 1 extra external cap on the motor and see if that happens, could be the internal ones are not working correctly.

If that doesnt' still work, see if you can swap out your crystals if that could be the problem.

how many runs are on the motor?
when i have a glitching problem with the newer motors i still add external caps.
but if you have to kick it to get it going i dont think its a glitching problem. either a bad receiver or esc. try a different motor. you may need new brushes. pull them out and make sure that the brush isnt chipped or burnt.

if its glitching, then its most likely some kind of interferince from the motor. if its studdering and all that, then its bad reciever, esc or low battery. check the esc on a different motor. and check the reciever in different truck. if you dont find the problem then, then start messing with the motor

you can file the brush with a fine file. you can also loosen the brush hood to see it was not seated properly.
