My favourite engine (HO) Atlas Master Series GP-7 has started "whining". That's the only way I can describe it. When I got is and for a couple months since it ran smooth and virtually silent. Now it sounds like it's in pain. Last night I oiled the worm (I think that's what it's called, looks like a screw. It's the gear that changes motor rotation into wheel rotation.) Any way, Can I draw on the wealth of experience hear for some advice? What's the possible cause and possible solution(s)? <br /> <br />Thanks, <br />Trevor[B)]
