ARE THERE ANY COMPETITIONS FOR QUADS THAT USE BOTH ARMS AND LEGGS  JUST CURIOUS,I KNOW CURIOSITY KILLED THE CAT AND GOT ADAM AND EVE BANISHED FROM THE GARDEN BUT I HAVE AN IDEA FOR A QUADBIKE AND IT SEEMS LIKE I AM ON MY OWN LITTE PLANET HERE.

I think you could run a quad bike at any Human powered vehicle event. Unless it leans, the velodrome events might be impossible. Quads have run before at these events, but they tend to be infrequent visitors.

Trike, what do you mean by "Unless it leans?" kindly please clarify it?

4 wheels are for cars, not bikes.
Trikes have been a proven stable platform for cycling. Why add more gear like a 4th wheel and additional drivetrain bits. |

Non leaning vehicles have a cornering stability index, based on the vehicles mass and location of the center of gravity, beyond which they will skid out or tip over. Any vehicle which can lean into the turn thereby moving it's center of gravity to compensate for the inertial forces may improve it's cornering capability.
A non leaning multi-trac vehicle will not be able to corner at the same speeds a similar leaning vehicle will. Also, because of the location of the center of gravity in relation to a line drawn through the contact patches of the outer wheels, a 4 wheel vehicle with the same trac width, basic mass, and center of gravity, as a 3 wheel vehicle will have better cornering stabilty. If both were leaning vehicles than the skid resistance would likely govern stability and the performance of both would be based on proper location of the CG to suit the vehicle design.
Think of it as being similar to sitting on a 3 legged stool compared to a 4 legged chair and rocking from side to side.
There are a lot of variables but if they are similar between all tires on the vehicles than the weight on the wheel, the angle of inclination, and the location of the vehicle CG will determine the skid properties of a leaning vehicle.
