I managed to get in two flights (the second and third flights) yesterday and I must say that I'm really liking my new UCD 3D 46. Question: I noticed that the outer axle hole in one of the wheel pants is starting to get hogged out from vibration. I don't know what to do about the vibration. I double checked the prop on my magnetic balancer and it's perfect. Since the first flight, I've replaced the stock plastic spinner with a 2" Hobbico aluminum spinner. I'm guessing it's a good quality spinner, but who knows. Anyway, this particular engine (Super Tigre G.61) ran well and smooth enough for years on my Super Kaos. Maybe I should replace it with a 4-stroke .91...
