Just flew mine for the first time 6-13-03 it is the same cub w/ a 61 os in it. I never had so much fun as flying off the water. The thing got off in about 40 feet or so, had lots of power, had to fly it at 1/2 throttle, or it clumbed like a homesick angel. Any way i got 10 flights on it now this last weekend. Good luck, and have fun. Gary Mpls. Mn.
