For the engine you plan to use in this plane, I strongly suggest a Model Tech Extra 300..(.25 size)....This A.R.F. is of excellent quality and can pretty much do anything the pilot is capable of. The thing I was most impressed about on this particular model, was that it didn't possess any inner demons that make it wanna snap a wing on landing. (A very nasty trait the ME-109 in the .25 size and the Tequila Sunrise made by Global are noted for).....Just a suggestion. Good luck on whatever design you choose to get.
