So I received my new Kraton in pretty rough shape and I ordered brand new model from towerhobbies. A few stripped screws into the plastic , all diffs leaking . Nothing I cant fix but I had a few questions and thought maybe you can all help. 1st is - Can you guys turn the front end by hand ? My front end will not turn from left to right unless I power on the vehicle , its like it is binding or possibly the steering servo is designed to only turn when power is on. Also the big red hexes in the pillow ball , should those be very tight or just hand tightened down ? Is anyone running a aftermarket receiver box with any success , my futaba will not fit.
