The Sig Fazer is a good choice I have had 2 of them and will be building a 3rd.Your os .40 will fly it ok that is the engine I had on my first one.although I do not fly 3-d I would think you would want a bigger engine to make it completely 3-d capable.IMHO If you are looking to go completely 3-d you will need another engine.
