How about a contest?
If for nothing else than bragging rights.
Two simple rules:
1. single propeller driven aircraft
2. must use glow fuel
any engine and airframe combination.
Top speed must be verified by radar and a photo posted, preferably with a police officer holding the radar gun. A photo of the plane and some specs would be good too.
We could pick a date as the deadline for all submissions.
What do you think?
