Here's a couple of my GWS Cub on floats. Plane was rescued from pile of junk in a garage. Notice the right wing is bleached out from being in the sun:)

Flies great with or without the floats. Comes off the water in ten feet. Uses the stock wire gear with a rear support attached with velcro and dental floss for bracing. Stock motor has been replaced with a Lens RC brushless. 3 cell 760 lipo for battery. Flies just as well on a homemade GB brushless with a single 20mm stator. Floats are hot wired from white foam and covered with colored packing tape. There's no water rudder but it's a calm day flyer anyway:)

Planning to build another one this winter in a red and white starburst.

Build one, you'll love it!

Mike Greear and Tony Frackowiak have E-Flite J-3s on floats..

It's been awhile since i've had time to work on my cub, but I just got the final details done on it for a test flight. The last few nights after work, I spent rebuilding the wing and installing airlerons. also I removed some dihedral, and installed a ''I'' beam style spar. I'll keep you posted on tomorrows flight!'' I may test it on wet grass in the morning.''just in case something bad happens mechanically I don't have to swim''

Here it is, I got my first flight in today! Check out the pics. I also shot video, but I haven't figured out how to put it on here yet.

Ok, I figured it out!

I'm new to electric flight and to floats. Attached are pictures of my first attemp at a float plane. It is a Wattage Cub, 47" wing span, 400 E-Flight inrunner brushless motor, 2100mAh 2 cell Li-Po battery. Weight on wheels or skis, 23 oz, with floats, 27 oz. I had the plane about a year and resently decided to add floats. These are the GWS floats. I have flown it off water only 3 times, then we had another cold spell here in upstate NY so there is no liquid water around right now. I moved the balance point forward slightly and mounted the floats with the step about 1/4 inch behind the balance point. Also tried to mount the floats with their tops as near paralell with the bottom of the wing as I could. When I flew it off water it was 3 channel. No ailerons. Only problem was it seemed to get twitchy on rudder control when on the step. It has a water rudder. Since then I have added ailerons, built up and covered, with hinges near the top to try to eleminate adverse aileron yaw. Reduced the dihedral to 4 degrees. Test flew it today, first with skis, and then with the floats, off of snow. It flys and handles fine, better then with just three channels. I have reduced the size and throw of the water rudder, but want be able to test until warmer weather. Any advice, comments or otherwise re directional control while on the water on the step?

Hanger 9 4046bL rotates quickley and flys great-hard to get down -wants to "float' for ever . Recommend highly

Nice looking plane. I have a Thunder Tiger Cub, 81 inch wing span, so about the same size except with .70 FS glow engine. I am planning on putting it on floats. What type of floats are those and the mounts? My electric cub crashed the other day. Lost radio control. I then learned that RJ Sport Micro receivers have a lot of interference in channels below 16. Mine was channel 15. I did get to fly it off water about 6 flights. It was some what under powered for take offs with a 400 brushless inrunner. It would come up on step quickly but then had to lower the nose and let it build up as much speed as possible and the apply lots up up elevator to get to unstick off the water. When it got up on the step it still got twitchy re directional control. A ventral fin helped some. I notice yours does not have the ventral fin. How is the directional control on take off?

WOW!! I like those!

Sorry to hear bout the crash -had that happen with gws rec.Got floats from Atlanta Hobby. They are from horizon hobby fiberglass for .40 - by Super Flying Models.I fabricated the mounts out of 1/8 x 1/2 aluminum.Plane tracked true without water rudder-however have not been in heavy wind . Very pleased with performace-afraid be too heavy and draggie but rotated very quickly and flew great -only problem it seemed to want to "float" for ever

Very nice photos, Sparky.

We are still waiting for "ice out" up here.

This Cub.. (slimer motor, sorry) was rigged as a Super Scooper.. touch down, fill up the tank while taxiing, take off and dump the water..sometimes over the flight line.. :)

I like the water drop idea.:D
Hey if you had left out the second pic, we would have never known it was a slimer. You could also have explained it as an ESC burning up, causing the smoke, while flying inverted over water at 30 feet of height.:eek:

There was one of those.. A "Caspian Sea Monster" type plane..nice smoke from a shorted ESC.
This Ultra Stik 25 survived.
Most electronics seems to slough off some water.. letting the water evaporate usually results in no harm.. IF the flier has cut the power back when the plane gets wet.. And drains all the water out of the wing! :)
That inverted shot.. he was dumping the water..

Couldn't pass this one up.:D
Hey, at least they're rc!

Sparky, I like the fishing pole idea. I don't care for a hook in my plane, but I'd prefer to get it back that way, than to swim in 60F or below water.:eek:
If you've swam in 50F water, you'll remember it!

Here's my Hobby Lobby Super Cub on home-made foam floats. The plane is modified with an 8" clip of the wings, added ailerons (was only a three channel model) and beefed up the airframe and wing structures a lot. It has a Cermark brushless motor and I usually use a 3S TP1320 lipo. It flies great!

Hey Sparky, I also converted a Gentle Lady into a flying boat (in the early 1990s)! It had a brushed motor on 8 cells and just not enough thrust to get out of the water. I still have it, maybe I'll convert it to brushless someday and see if it can fly.

Got it off the water by adding 3/16" upthrust to the pylon.
