Years ago my Raptor 30 went under 4 feet of water. Took me 15 minutes to find it. Took everything apart all electronics engine gyro and put a fan on it for 12 hours . Put it back together and everything was fine except maybe the battery. If it was salt water no chance I would presume.

Setup is everything, All my heli's can fly far better than I can pilot them

water would it float or sink
Reminds me of that song..."Should I stay or should I go"...or whatever is was......

Somebody mentioned Archimedes and he defined "how things float" about 2000 years ago or so...

If the amount of the water's weight, displaced by air, is = the weight of the materials used to displace the water....that's defined as "neutral buoyancy"...as principle that submarines use.

When a boat is designed to carry cargo, the weight of the water displaced is huge as compared to the materials used to make it float....lot's of heavy steel used in the Titanic.

For our helis, our "cargo" is heavy batts(engines if nitro), motors, ESC, servos, cables, etc.

Only the canopy seems to be able to displace water....if you "auto" in the water perhaps, until the ESC cooling "air holes" allow the water in....if you crash, that canopy is gone.

Yeah and that's when it's flying! You should see what would happen if it landed in water!

Wow that interesting. I thought for sure the electronics would be toast.

Me too!! If in salt water for sure done! I broke down and dis assembled all the electronics as far as I could ,layed them out on a towel and aimed a fan on them for many hours.
After reassembly I was very surprised everything worked including my tail gyro. I flew it for another year or so and sold it.

Setup is everything, All my heli's can fly far better than I can pilot them

Is there something small I can strap to the heli to make it float? Just enough so it doesnt sink to the bottom?

Maybe an empty fuel tank would work.

That, plus crash only at the end of a flight so both the spare and integral tanks are empty.

Better yet, why are we flying over water? Can we not do this?

Electronics are cleaned using water when they are manufactured. You cannot damage the electronics with water with the exception of some parts that can trap water. If the water is removed before corrosion can take place then even parts that trap water will not be damaged.

One can recover the electronics from a crash into salt or fresh water if you do the following;

1. Do a thorough wash with clean water under a running faucet. Force the water into all the cracks and crevasses. The goal is to displace the salt water or lake water with fresh clean water.

2. Using compressed air blow dry everything as thoroughly as possible. DO not be shy about blowing out the electronics. Open cases if necessary. Blow into every opening that you see. Motors, connectors, circuit boards - everything. Then blow it out again even more thoroughly.

3. Blow out the bearings and lubricate with WD40.

4. You will probably not be able to get all the water out of the battery unless you remove the covering. Remove, dry, replace if necessary.

5. Let everything dry overnight.

6. Chances are very good that everything will work as before.

Rule No. 17. Never fly over water without having pontoon floats on your helicopter. Water is a helicopter magnet.

I have a nano qx that landed in my pond.....lost forever. Or so I thhought.....three days later a little girl was fishing on the pond when she came up to me and said she found my little quad. Sure enough she had my nano hanging off the end of her line. She snaged it bottom fishing.
I gave her $10 for finding it .....took it in and cleaned off the worms and pond muck.....blew it dry then stuck it in a bag of rice to draw the rest of the moisture out of it....next day charged the same battery and been flying it ever since with no issues.

Pond tested pond approved.
