well i talked to the guy at my hobby shop and he said he could sell my used 61fx for a pretty good price and i also have a new 42 size engine that has never been started and he will take that in on trade and now i'm thinking of just buying a fourstroke and getting a ys 110 and putting on the plane at least i will deffinatly be getting what i wanted and thats to over power the plane this maybe a bad idea so what do you guys think i would like to hear from you before i order this motor and one more thing would the tail wires be better and simplier for me to use thanks for all your help.
