The pictures show a clean engine with a very dirty prop bolt and nut, a beat up fuel tank, no muffler and no view of the throttle. And a ding in the muffler mount that even a gasket won't fix. Is that what you want us to see?
what a fool get glasses!!!!!! cant believe i answered back he doesnt enven know that a U CONTROL MOTOR has no throttle
Sorry, the U-control engines I've seen that are bigger than .19 had throttles and a third wire. That big engine can get a lot of speed in a dive if not throttled back. I rarely saw even .35s though and never a .46. Maybe the throttles were homemade - it was many years ago.
