Nexus that looks great nice work that engine looks great too like how you have put the exhaust inside that must have took awhile to plan out. You have just made it hard for me now I had dropped te idea of one of these and stated looking at the Kyosho Kelly F1 now I don't know what to do. I was going to use a V twin 4 stroke I've got a 150 and a 200 V twin but I think the 200 would be over the top and would not give me speed anyway and the 150 not enough. What kind of weight does this thing come out at?
