RE: Readyfly Cessna with flaps
I turned mine over once by catching a wing tip during a takeoff on a choppy lake. (As you might imagine, we do have some windy days here in South Dakota). It was about 10 minutes on its back in the water and when I took the wing off, I found absolutely no water inside the fuselage. I was truly amazed. There are some small opening where the gear struts leave the fuse and, fortunately, these were above water.
I took the glow plug out of the O.S. .90 four stroke, turned it over with the starter a little, reassembled it and flew again several times the same day.
I smear some vasoline on the wing saddle when I put on the wing. That is the only precaution I take to keep out the water.
I had a Modelfly Ready and sold it to another floater when I bought the Cessna. It is a great float airplane too. I completed one of the new Beaver float planes last fall, but as yet, have not flown it off the water. A picture of it is in this month's R/C Report. So far, the Beaver has not been as good a flier as the Ready. It has the same wing but the fuselage is quite a bit shorter coupled. I'm still experimenting a little with the CG.
