FPV Maritime Heli...from scratch

OK, here's my next project. A FPV RC Heli.

I was 1:1 scale pilot with around 2500 hours in big helis...but I can't fly an RC heli to save my life. When I started flying RC planes, it was a slow start until I put a camera on the plane and goggles on my face. Hopefully, I "get it" with helis as well.

The goal is to be gain enough skills to take-off, fly around and land from the back of a kayak.

I got a Honey Bee King 2 for Christmas, last year. I'm going to start with that.

It took me about 6 monts of thinking and testing before I got to the light house. This will be a longer project. Be patient. Hope you stick around and help.

it would be pretty foolish to land a heli that close to yourself especially when you are trapped in a kayak unable to run away (maybe you have a really big kayak). don't underestimate the power of a blade strike from a small heli, or the motion induced by a small puff of wind. those blades are moving very very fast, and have lead weights in the blade tips. I hope you have G4 or another good simulator to learn with. don't even bother to fly the real thing until you can fly in the simulator. if you crash in the simulator then you will crash with the real thing.

Very aware of what rotor blades can do...

Plan to build a small landing platform and a "hangar face" between me and the helo...

Having a headwind helps, just as in real life. I'll probably wind up getting a small trolling motor to make way instead of paddling.

I'm used to flying off these. You get the concept...

If it can't be done on a kayak...I might have to do it off a cabincruiser instead.

Eitherway, I'm going to take small steps, methodically...Like I said, it will take a while.

Thanks for the criticism. Keep them coming.

Nice goal. It may take a while .. escpecially if the kayak moves and the landing platform (with person protection) is only as narrow as the kayak.

Maybe it's an option to try it first with a small Quadrocopter? The walkera Ufo or an X-3D-BL (or Mikrokopter) can't hurt you and maybe they are a little bit more easy to fly.

I was thinking that a coax might be helpful as a stepping stone, but I can't think of a model that is big enough to carry the FPV gear. I would also be concerned about tipovers, particularly caused by movement of the kayak even after the heli is down. Maybe you could build a frame with a net around the helipad to catch it if it goes over.

Maybe if I crash the Honey Bee King 2 beyond repair.

It shouldnt be that hard if you have 2500 hrs of full scale, the feeling is quite similar. I`ve only been flying my trex 450 FPV a lot for a week but I could definately land it on a platform, especially now that I've taken the time to balance it and fix all the vibrations I had much smoother flights/ videos to come.

Pretty cool idea you have there, cant wait to see how it turns out.

Taking off wont be a problem just pull on the collective real quick and you`ll skyrocket up

Flown in wx like this...Not fun but do-able.

Had to deal with this problem in real life as well. The full scale solution is the "RAST" system...

My solution:
Hold the heli down with rubber bands over the skids before take off...and land on a bed of velcro...


BTW...I managed to learn and teach how to land on boats without ever having to test the bouyancy of a helicopter...It just takes tiime, good procedures, and patience.

I would install powerfull magnet on your skids and electromagnet on the platform, so you just have to come close to the platform and the heli will land straight each time...





it's a joke if your not sure

A joke? Why? It´s a great idea Denis


Actually I thought landing on a kayac is not a good idea until I read this


Maybe you wouldn´t need it to be electromagnetic. If you find the exact magnet strenght needed to keep the heli in the kayac, but that the heli still can take off with full throttle, that might be nice
