Long Range FPV Helicopter RC Flight, need help

Hi everyone !

I have for project to make a helicopter I could control from my computer with radio waves. The system would not need auto pilot as I would pilot it with help from video imagery and radio waves. The video imagery will be captured from a video camera on the nose of the helicopter but I don't know how the video feed is going to be transmitted, as I need continuously clear video and radio transmission to control the helicopter.

The helicopter should be at first take off and be piloted from eye, and then the pilot would use the fpv video feed to pilot it from distances. The rc helicopter should be small and cheap, but capable of transporting mini payload and be able to flight quite easily with quite good stabilization. I don't need it to be 5 km far, but to be in the air at a mid distance providing clear radio and video transmission.

So, my main problems are :

 

- The video transmission.

- The radio control of the small helicopter at fairly good distances.

- Which RC helicopter / airframe am I gonna choose.

 

What are your solutions and advices for this ?

 

Thanks for your future answers.

 

PS: I don't know if its the good forum, but it was either not in arducopter, and since my main problem is the aiframe, I decided to put it here, thanks

PPS: I did many research work but I couldn't find my happiness. I found a "how to create your own rc helicopter" tutorial (which is here: http://www.angelfire.com/blues/heli_project/index.html but his main material is made of circuit board with the copper layer removed, I think there are easier and cheaper ways to maybe buy one already existing rc helicopter and then mod it, and since my project doesn't need auto pilot but long range fpv...)

PPPS: Sorry for my english.

Haggard,

Your project should reflect the problem you are trying to solve, what is it exactly you want to accomplish?  Once you establish a goal you will find yourself much more focused on the design characteristics.  

For example: if you plan on doing aerial photography then stability will be very important; however, if flight time or duration are important, less motors mean less current draw.

And if you can't find any inspiration on the web, you really haven't been trying.

I want quite good stability but 10 to 20 minute of flight. I just search the CHEAPEST solution beetween quadrotors and helicopters.

Helicopters are the cheapest I think, i'll go in this way. Thanks anyway.

What I want is 1km video&radio link, no more but I accept less, and mid good stabilization, the camera should not be too shaky. I would maybe need some payload (ill try to put one watergun on it)

if you want to put a water gun on such a small heli, forget it, water is waaaaayyy too heavy...
