Yeah I did notice the motor has some strong magnets in there for its size. I guess it needs them to make this much power off of 4.8volts. I checked and my gear mesh was a little tight. I also put the small pinion on and now it will hold a wheel for about 10 feet on a fresh charge! This things hard to control at high speeds anyway.
I also broke one of my lexan turn buckles just like the stock plastic one broke after it came in contact with a chair at full speed (trying to make a high speed pass under it
). Easy fix... I'll see if leaving more material around the screw will help. Its been breaking right before where the tie rod screws into the steering ackerman. Its not even tearing at the hole where the screw goes in so thats not the weak point.
