I started this hobby by having a "freind" buy a used Hobbico Super Star 40 on my behalf. He now can't come over to the house or my wife will castrate him. Joke. Anyway the used plane had an OS 40 LA on it. I crashed that poor plane numerous times. Couple nose in's even into asphalt. The engine kept running. After terminally crashing trainer I have it on a Kyosho PT 19. It's not fast but does a good job of letting me warm up before I fly my GP AT6 with my new OS 46 LA. It screams. People at feild can't beleive its a 46 or that it's an LA. I do have Simline sport muffler. Can't believe all the bad posts about LA's. They have helped me get and stay in this hobby.
