I have seen a few tri float, (old timer, hot timer) float settups on here but they seem to be not very popular. By the sounds of the owners of them, they seem to do very well on the water and in the air. Why is there no following of them?

I decided to give it a try and so I took the tower uproar 40 arf I had sitting in the box for over a year and put it on tri floats. I still have to mount the engine and radio gear but the floats are on and I think they are going to work good. I don't know exactly what angle to put the bottom of the floats to the plane since there really isn't alot of info on them. I have it set up so it is easily adjustable. I made them out of some white styrofoam and used 1/4" plywood glued into the foam for mounts. Carbon fiber arrow shafts for the spreader bars and 1/32" aircraft ply on the bottom from about 3" in front of step back to the step for a little protection in that spot. I covered the front floats with monocote and it seems to be sticking well and covered the rear float with econocoat which didn't stick quite as well. The front floats are right about 3.5" wide and the rear float is 2" wide. I may be able to make the rear smaller but didn't know just how much weight it had to support until the plane is done. The size now should float about one pound of weight and the total airplane I hope will be under 4.5 lbs.I will upload some pictures of it tonight.
