I just ordered a M.T. Extra 300 .25 size ARF because it is so cheap- and sounds like a lot for $80. I plan to use a .30 FS Magnum in it, and widen the ailerons and use them as flaperons to get slower landings. This plane has been advertised for several years, and there should be people experienced in flying them. I have heard of .40-.46 2S engines being used in them, but I prefer slower planes, and hope that the FS with a large flat prop will put it thru its paces. I'll apreciate any input on this model.
