I just rebuilt my twist after flying it with a p.o.s engine and an encounter with the top of some tree's after a dead stick or should I say after another dead stick in fact every flight with that engine ended with a dead stick anyway just for the heck of it I stuck a magnum 61 four stroke in it. I picked up this engine in a trade and decided to give it a try. After running it up on the ground I don't think it will have the snort I like in a plane but I'll give it a whirl maybe play with a couple props and see how it runs and flys. My next choice would be my Webra speed 50 but then I have to add a heavy hub for balance and I don't want to have to do that, maybe I'll have to spring for one of those Saito 80's. I'll have to take the twist and my funtana 90 out this weekend and see how both of them fly, I had so many problems with the first engine on the twist I didn't get a chance to do much with it and the funtana is brand spankin new and has a big plenty of power with the O.S. 1.60 on the nose [X(].
