Dewoitine D520 looking for feedback
I am looking at building the D520 from Bates plan. I want something that will fly good and that could stand out at any fly in event. I already have a Byron T6 101". Anybody out there that built the kit before?
how about some feedback on the plane itself? would this be a good subject for the scale master in a couple of years?

Hey! I found you on R/C Universe. Well, this Dewoitine should be an excellent choice. Having looked at your plans last night makes me confident in the airplane. Should be fun to fly. From our study it looks like Jerry Bates put an NACA 2418 at the root of this airplane. Nice airfoil. Yet I feel strongly that you should consider dropping the incidence from 2.5 degrees down to 0. Failure to do so will give the plane a tail high look in the air and lots of down trim in the elevator. This airfoil produces a .15 CL (Coefficient of Lift) at 0 deg. and a .50 CL at 2.5 degrees. I don't think you need that much CL at cruising speeds of say 80 mph. If you give me your wing area I can calculate the CL you will need to fly at any given speed. I will send you a spreadsheet to consider.

I make a kit for this plane.
Jerry is by far an under-rated designer. The D520 is a solid scale design (like most of his planes). He tends to design with "chunkier" materials, but makes light wood choices. The result is a plane that is solid, fairly light, and not over built.
