RE: AkroMaster CL-20
formula 51,
How much building/flying experience do you have?
The reason I ask is that if you are new to flying I would suggest you build the plane without the complication of flaps, and put a more "basic" finish on it because you ARE going to crash it. Be more concerned about building it true and accurate, and how to get the best run with your engine.
OF course if you already know the basics, go for it.
Good luck either way.
