Im new to rc's. Just got a used stampede 4x4.

The issue I have is it jerks/stumbles/hesitates every time I take off slow(less then 1/2 throttle). From searching I found to try and loosen the slipper clutch. I loosened it to the point that the truck would hardly move. But the truck would stil jerk a couple of times before going. I tried it with no gear/load on the motor and it seems to work nice and smooth.

Another note.... The truck doesnt like to wheelie. Stock gearing, tires and new 2s lipo. Is this common on the 4x4. Almost seems like the front tires are doing more then the rears. From gthe vids I watch it seems like I should be able to wheelie.
