We are seeing increased interest in over water still and video work.

These are Helihobby floats for a .60-.90. Theve been modded to remove about 40% of the stock wieght.
Tested for the first time today and the video looked real good. I thought theyd buffet around during forward flight but they dont.

How'd the launch/land go from water? Did you reduce your pitch curve at landing?

We dont need to take off from the water. The floats are for forced water landings. This thing autos great. Hope to never have to use these floats but feel much more at easy knowing they are there.

sweet! I never could get the right setup for my maxi, because with the copterfilms setup, the cg is too high. I'd recommend a float on the vertical tail...

Rhett..... I can't fly, but the Profi sure can.

I bought some floats for some possible future work. With the short 6 minute flight times of the Trex 600, I figured launching from boat and landing on water would give some elbow room to trying to land back on a boat with winds, etc. More margin for error.

Have yet to use them.

Ive never used floats off water either but i can tell by swimming pool time today that spool-up would be a lesson in counter-rotation. The Jazz controller we use has auto-spool-up so im sure that would even be more fun as the chopper did a couple piros before the headspeed came up.

I've launched of ice on multiple occasions, guess that's not the same or even similar?

I've took off and landed a few times with floats. The biggest problem is spin-up/spin-down vibrations can really get amplified at both the float attachment point and at the water line. Sometimes they aren't so bad or even noticeable, but sometimes watch out. They could easily tip over a heli.

They are certainly fine to keep a heli off the bottom if you have trouble over water. You may even be able to land OK assuming no big waves, but I wouldn't plan to take off and land on water. Is anybody doing this routinely with an RC heli and inflatable floats?

I have used those floats before. They work pretty good, but if you fly a gasser or nitro bird, watch out for the hot exhaust... it can burn a hole in the vinyl (don't ask how I know this...) However, if you ditch hard you can kiss those floats good buy, as the wood will split apart leaving your floats, well floating and your bird sinking.

Noticed that wood looks like itll disolve if it gets wet
Nice pieces of CF would be great no?

Or G10 if cost is an issue. Infact i would use G10 anyways as its just as strong and in the floats wouldn't be seen.

I just coated the wood with something waterproof. Don't remember what since it was nearly ten years ago, but most anything will work.

Even with CF if you come down hard all bets are off.

One thing I noticed in the pic is that the CG is pretty much centered. I like to put the CG a little forward, reason being is that you are going to flare with the tail low, if you make a balls of it at least you don't have a chance of dipping the tail into the water (not good, its like hitting solid concrete and tears stuff up) or worse causing the heli to flip backwards and upside down.
