Ultra Micro J3 Cub Mods?


I am looking into buying or making floats for my ultra micro j3 cub. Does anyone know of any out there? Can I make my own?
Also, are there any extra mods or anything? And what are the best upgrades, batteries, motors, etc. that I can get for this plane?

Thanks,
Darien

There are floats out there I just can't remember the name of the plane I got them off of. I'ts a profile rubber band powered beaver that mine came from. It flies great with them on.

Maybe you could cut down a pair of the 350mm floats and make lighter mounts.

I've cut my own with a hot wire cutter, but they're flat-bottomed.

I have been working on a set of floats (Scale Design) for the Micro J3 Cub. While the plane flies and looks great in the air, (really looks good) it will not take off of water. The little plane just does not have enough power to break the surface tension of the water and it is not going fast enough for the step to be of any use. We can land it on water just fine with a little practice. Land on grass just fine.

Any interest out there for floats that look good but you are limited to hand launches?

BTW: We are still working on different designs to see if we can get it to ROW

You guys know how to go with design, but I did just find this very informative page, while looking at floats. The dimensions stated can be scaled and adjusted for the model.

Perhaps it'll help other folks who may wish to modify for water fun

Getting a full scale J-3 on floats to ROW isn't that easy, either! If the water's smooth, many guys will taxi in a circle, then use their own wake to break the float free of the water. Of course the surface tension is much greater on the UM Cub due to scale. I wonder if a lower pitch prop would do the trick, or maybe larger diameter to move more air?

Have you tried using " RainX " ?
Might help with the surface tesion.

I am definitely interested just for the looks of them. I am not concerned about not being able to take off from the water.

They do work well and the model sits correctly on the water. The test pilot(s) report very favorable flying characteristics. Landings are shot with some speed, which adds to the scale effect.

The model will not ROW with the floats as they are now. We are testing now with the floats having a flat bottom.

More to come on this.
I'd like a pair of your floats. If I can't get off the water it doesn't matter much because I don't have anyplace to fly off water except when I go to Vermont, which is only twice a year or so.

I just like the way a J3 looks with floats on and I can use them off snow also. When I was a kid I used to see cubs with floats on overhead all the time. I think I lived half way between City Island, NY and Little Ferry, NJ, both of which had a lot of float planes.

I'd like scale floats, but if the flat bottoms work on water I think I would go for both.
