Hello. I rec'd my VS Abrams today and have a problem. It has 3 forward speeds. When I use speed #2 sometimes the tank will stop moving forward and the function will change to raising the barrel of tank. It does not do it all the time but often enough to be annoying. Speed 1 and 3 work fine. Sometimes when I press speed #2 the tank does nothing but raise the barrel, other times the tank will move..but then stop and do the raising of the barrel thing. Anyone experience this? I ordered this from toyeast....thanks (I am not accidently hitting the control button to raise the barrel..)
