Just to be clear...what I was referring to was the Great Planes kit, not the preassembled. I certainly can't recommend the kit unless you've got the time to enjoy building them just for building's sake. I'm currently between working contracts so had the time to build, and had a lot of fun with it. But....by the time you buy some music wire and monokote, and a few other assorted items you'll be close in price...so no real money savings and I spent two weeks getting them all together.

I don't have a real good scale (I'm going to correct that soon), but the cheap one I have shows my trainer at about 7 lbs with my new floats. The plane was about 5.5 lbs before...so the floats are about 1.5 lbs complete with struts and cables (these figures are rough but certainly well within a half pound and the actual difference I measured has to be even more accurate). Other threads on RCU have shown that at 1.5 lbs I'm probably a little heavier than most finished kits. I'm wondering if the 4+ lbs is even accurately reported by Great Planes on the preassembled? Dang those would be heavy.

My completed 40 size kit floats are exactly 34.5" long...measured. They must have carried over that value as a typo to their new float's box label. I'll bet they split the difference in the kit sizes to make it work for both 40 and 60 size planes and made them a generic 40". But as PeterC said above, I'm certain even the ones I have will easily float a 60 size plane. Keep in mind that your floats should be about 75% of your plane's length. If you haven't bought floats yet, jrf's recommendations are good ones (but I do love the floats I have...but you need the time, normally I don't and I'm just a happy ARF guy ).
