OK flew this 8 footer with an OS .60 2 stoke on wheels, takes about a 50 foot runway.
On Floats! takes about 200 feet and needs some rocking to get it up, but was better after I used flaps.
Installed a Saito .91 Golden Knight, inverted. and run in on ground, then a few flights on wheels before leaning out.
It uses about 12 feet of runway to take-off with full flaps. and about 18 feet with no flaps.

weeeee.
I reinstalled the floats, and flew it on water. The engine ran flawlessly.

sounded awesome too.
I practiced taxi'ing a bit, and then went about 2/3 rds throttle, dropped the flaps and,,, the plane lifted effortlessly out of the water. surprised me as I was expecting to have to wait for more speed.
Done some scale slow speed flying, then went radical, Immilmans, snap rolls, Loops, hammerhead stalls! This thing has almost unlimited vertical! even with floats. I could hear the kids on the beach squealing everytime I done a radical move! Loved it.
Meanwhile the wind kept getting stronger, and this thing flies about 40 minutes per tank. average on 1/2 throttle. 16 oz tank.
I put 1800 Ma Batteries in the plane, so I don't have to worry about low batts.
After Landing, I ran out of film, and was taxi'ing it back when the wind got under one wing and rolled me over in the water. awww!
retrieved it. left it upside down until the water drained out. and then turned engine over slowly to expell any water it took.
re-started it. set it back down in the water, left it idling.
went to pull up the boat anchor. and the wind tipped it over again. (heavy sigh...). retrieved it again. called it a day. went home. re-installed the wheels and went flying it that evening.
GOlly Gee Gosh! I love this plane. LOL
I posted a bunch of photo's in the Gallery! and some showing the False Belly pan that allows me to change from floats to wheels in about 15 minutes.
Smoky.
