Hi,

I fly mine with a ASP 108 2 Stroke, with a pitts sytle muffler and it flys faultless. Althou a four stroke would sound lovley in it.

You will make an excellent choice on this warbird. This is my fav plane out of my fleet which is now approaching 15 planes (Must stop buying them) the problem comes i need a bigger car to cart them around in

Good luck on your choice and if you need any building tips or advice plz post
