Me? I think one 16oz is too much... but you guys can know yourself out...

At least they'll be on CG.

I would think a 16 oz on the 80 would get you a clean 15 minutes with time to spare... but 16 oz of smoke fluid is gone in a heartbeat from what I've seen.

This would be purdy with smoke, but with the 50cc it would definitely only fly sport. Dual 24's WOW... 3 lbs of liquid in a 20 lb 80cc plane... 23 lbs wet.... That seems like an aweful lot for 1460 sq in... at least a significant change of flight feeling from start to land.. Somebody needs to invent wingstretcher...
