Full Rules are at
www.balsabeavers.com . Basically 300 sq. in. wing like a Foxberg or SSR , 60' x .015 lines , LA .25 stock except backplate and NVA can be changed . Stock 8x6 black Masterairscrew props only. Tank size is up to you , shutoffs are recommended .
I think a lot of people will have airframes that will work already . The Super Fly is popular up here .
Pilots need to make a "pit stop" before the flight , double knot those shoe laces , put on the sun block , hydrate before and pack bandages for the blisters after. Beer is recommended for electrolyte replenishment .
I'm thinking Brodak's will be a lot hotter than Toronto is at the end of September . T-shirts and shorts are more fun than parkas and mitts !
