I have a brand new M41 Snap On Edition. I couldn't take the graphics on the standard model! I upgraded the rudder, cooling jacket etc with Hot Racing parts before running. Anyway, just took it out for the first time and when I would accelerate the boat would suddenly make a hard turn. It was getting dark so brought home. When I have on stand, I press throttle very lightly and the servo starts to turn slowly and keeps doing that until I let off the throttle, then snaps back center. Any idea what might be causing this? BTW, the steering was reversed, so I reset the controller when I got home but still the servo issue.
