that pretty much sums it up. while a small norvel will actually go down to about 2 oz (were talking litle .049 check it if you don't believe me) that's including the muffler but no fuel. so call it 3 oz. but they are a little too loud and dangerous to be flown in the park. not to mention, they sell for about $40, w/o servo. while you can get an electric motor and setup for $40. also, any plane light enough for park flying most likely won't withstand the power. also, what if you run into somebody. while i am a good pilot, one day tue to several reasons and a gws park flyer, i managed to smack a bald guy right between the eyes wiht my plane's spinner (don't buy gws recievers. i flew over a guy on channel 40 and servos went nuts and i am on 22). that was at the flying field, and the only reasons he didn't pound me are that #1, my dad was there and i had my pocket knife in my hand working on taping a hole in the wing when he came over to ask me what happened and
#2 he asked if i had a gws reciever and when i replied yes, he walked away. what if that was a small gas engine?

later that day, the spinner fell off somehow and the gust of wind (i shouldn't have been flying) got under the wingtip of that light plane and carried the plane over to the nearest tree. the propshaft hit the tree and it drilled itself into it, and there is stood for about 15 mins looking really stupid, stuck nosefirst into the tree until i gave my buddy a lift and he took it out. that would have done some damage to a little .049. that propshaft made it about 5 turns intothe bark until the fuse i had blew. lucky for me, i had a spare. i handlaunched it into another gust, which did the same thing when i tried to compensate and sheared the wing off on the local friendly stadium lightpost. if the tree wouldn't have taken your little engine out, the pole would have. god how embarrassing. anyway, the point of this speech is that even if your plane could handle the engine and it wasn't more dangerous, the "hazards" of a park are too great to risk an expensive little engine.

right after that, i hand
