Well I did my best the WACO was Tail heavy about 5 ounces with
the magnum 28 on the front, so I put an old Tower 46 on the
plane and she balanced out perfect. Did anyone else have this tail heavy balance problem? Also I took the suggestions and did the CG it came out to be 3 Inches back on the top wing does this sound right. I will give it a test flight Saturday if it is not so windy.

I just measured mine and it is at 2 7/8" from leading edge of the top wing. Yes, nose weight was necessary. I made a 1" spacer to move the engine forward so I wouldn't need as much lead.
