Helicopter quad frame

I had a idea which may or may not work, that is to get 4 cheap heli kits and build them up leaving the tail rotor gear off and then join the booms to a centre chassis to make a quad.

Is this possible ?.

When was this first thought of and applied ???? see below pictures

The very first was 1907: http://www.aviastar.org/helicopters_eng/cornu.php

I find this to be the case every time I try to come up with something new.

Lol thanks

My thoughts were to use 4 of these https://www.hobbyking.com/hobbyking/...arehouse_.html , my concern is that the kk2 board will increase head speed but not collective, thinking you would have to y lead the collective together ?.

I've been wondering about this too.

Did any of those examples include Cyclic Pitch?

The experiments I've seen so far are with only Collective (Variable) Pitch.

Would there be any advantage of including Cyclic Pitch (ie Elevator & Aileron control in each individual rotor), as would be the case in the OP's suggestion?
Or would the rotors just be fighting each other and the overall effect???

Cheers
