This could be one of the most baffling car issues I have ever had.
Problem: Car will not accelerate, most of the times. I give it full throttle, and it just sits there. I then give it a little push from behind…and then it goes. It runs ok, as long as I don’t let it come to a compete or slow stop. When it does again, it will not go, not until I give it a little push again.
Areas that I have checked: NEW T1R car, NO binding at all. Without the motor installed, the car will roll down my driveway, no problem. NEW TO Rush 11X2 motor. The motor shaft spins pretty freely, with the obvious magnet forces.
Things I have tried:
New ESC (confirmed working in another car)
4 types of battery packs, all work (according to charger, and when the car wants to run)
ESC with Battery Ultra Deans
6-cell Fukayama Battery pack (4)
ESC Deans connector to Motor wires.
FM RX and Radio
LRP F1 PRO Reverse, no motor limit ESC
TO RUSH 11x2 motor
With the car on the working bench…I have tried:
Replacing ESC with a MC230CR
Replacing Motor with a Monster Torque 27t stock Motor
Direct solder ESC to Motor leads (on both motors)
Installed cap on Motors
Installed cap on Battery connect (on ESC side)
Tried all combinations of above mentioned options with motor installed and un-installed in the car.
Used a watt meter (Electronics are only pulling about 9amps, BOTH ESCs on both MOTORS)
No matter what combination I try...the outcome is the same. FULL servo operation....but no motor power. Then...I can disconnect the battery pack, motor and ESC...come back about 5 min. later, hook it all back up...and it works. The motor spins.....but only pulling about 7-9amps and the motor sound flucuates when i have it at 75% to full throttle. I start to ease off the throttle....to a stop, and BAM.....when i give it throttle again....NOTHING! No Amps....nothing! AHHHHH!!!!
This is killing me!! I feel like I have tried ALL possible options….and nothing has worked!
Any suggestions would be great…as all of this equipment has been run MAYBE 5-10 times….so it is “like new” condition!
If you have any tips....and you can Email me....PLEASE DO!
