I had my volcano epx pro about 2 weeks and bought a lipo 5000mah. Wow! that thing is fast! but i broke one of the hubs in the front and lost one of the dogbones. so i took out the other front dog bone and am just running rear wheel drive. When driving i noticed that my right rear tire has alot more torque than the left one and will cause the car to pull to the left. My question is, is this normal because I am running only in rear wheel drive or did I strip some kind of gear. Thanks.
