Hey guys,
After getting fed up with the lack of torque and cogging on my Mamba setup I decided to switch back to the brushed configuration.
I wanted to use my existing 3-cell Lithium cells so I tried these:
Setup #1:
Futaba MC230CR
Apogee 1660 3-cell Lithium
Graupner 4.8 volt (stock pinion)
I ran this indoors with good results and okay temps (150 motor, 120 ESC, 90 batteries). The car was very fast and powerful. I then installed the body and took the car to my garden, after about 5 minutes of running I noticed that car had no power. I checked the temps again and noticed the motor was 250°F. I ran it a couple more times and then the motor died.
Setup #2:
Futaba MC230CR
Apogee 1660 3-cell Lithium
Stock motor (16 tooth pinion)
I had to install a 16 tooth pinion since the stock pinion wouldn't come off the Graupner motor. Once again I ran the car indoors but this time with the body. The car once again ran good and strong. Temps were good too, after about 10 minutes of hard running the motor was 170, 110 esc, 83 batteries. I had yet to try it outside but I think I should purchase a stock pinion before taking it to the garden. I think the 16tooth in overkill.
I am very impressed with these Lithium cells, I've never finished a battery charge yet. I played around for 5 minutes yesterday and recharged the pack. The charger only put in 110mah. THAT'S CRAZY! That equals to about an hour of run time.
