Flying Off Water


Just wondering if anyone has tried flying their e-heli off water. I just put a set of floats on the E-Shuttle.

Any suggestions for how to approach the first takeoff? I built a turntable thinking that taking off from it might be similar to taking off from water.

I would have thought that it would be like a take off from a smooth surface, buts its gonna drift more readily, just dont let it build it up to much speed on water so it cant dig in and tip it over.

I guess you have to fly it before it leaves the surface, paradoxically

Yikes! I have enough trouble flying it AFTER it leaves the ground!

I was thinking the biggest thing to get used to might be the heli spinning. There is almost no resistance to rotation when spooling up on water whereas on the ground there is a fair bit of friction.

I suppose you also wouldn't want too much negative pitch or there is a risk of sinking too deep in the water.

Just watch the idle up setting!! I watched a guy onetime with a Rappy on floats push his underwater with neg pitch

It is not a big thing to start from water. Make sure you do it on a calm day. Start by LANDING on the water, use your T/R as you normaly do. Dont let the blades slown down to much in the beginning, just "hover" on the surface, to get used to the feeling.

Then it is just to practise on the T/R. Donīt be scared if you need to give FULL T/R to keep it from spinning, this is normal. The full size heli pilots do this on GROUND.

Well it is very cool to see the blades swirl up the water around the heli. But make sure you have your r/c gear in water proof bags, or use ballons.

Good luck and watch out for sharks!

Thanks for the shark warning, Tom. I never thought of that one!

I don't have the receiver or gyro in bags but I can put the receiver in one easlily enough. I don't really need to put the servos in bags, do I?

Cheers,

The servos can handle quite a deal of water splash. If you want you can tighten the servos with silicon, or just electric tape.

But hey, you are not ment to fly UNDER the water...

What kind of heli are you going to do this with?
I have put some foam floats on my Corona, and it is very cool to start and land on the water.
Its abit more thrilling to do it over water, belive me!

The heli is an E-Shuttle - an ordinary 30-size Shuttle ZXX running on a Tango 45-06 and 21 cells. It is fitted with Heli-Max inflatable floats.

Putting the ESC and the Battery in balloons would effect the cooling I would think.... My nephew and I use balloons for his Rx and Battery in his nitro boat. It has saved our butts several times...

Sounds like I should at least protect the receiver from an unexpected "flood".

I'll try flying around with the floats on dry land first. I'll try taking off from, and maybe landing on, the turntable a few times before I actually try it on water.

Thanks guys for your input!

I would think putting a keel on the floats would help in the spin department.

How about little rudders attached to the tail servo ?

OK silly idea thought I would throw it and see if ti stuck
