Rossb : I trust you.... you have build your car correctly according to mtx5 instruction manual . Sooner or later you have to bring your car to track and have it a road test. I'm sure it will be fine. New build car need break in time. Dont listen to blis too much ..... trust your build and the instruction manual.
Blis : I dont love this hobby regardless of make and model when smart people like you around.... ok?
