In sports, they keep records and stats on everything. In our hobby, not so much. Therefore, I can claim a record without having to prove it.
On Saturday, I set the world record for the largest difference in weight of two CL airplanes flown on the same day.
I started the day flying my Wee Wun, a British-designed plane with a 15-1/2-inch wingspan and a total flying weight of 2-3/8 oz. Power is a Cox .010. I built it to prove that you could build a stuntable plane for an .010. It stunts.
Later in the day, I flew my Crossfire, a 65-oz. electric PA plane.
That is a difference of 62-5/8 oz., if my math is correct.
Do I get a certificate, or a trophy, or something?
