Is the effect that the propeller slipstream (i.e the helix) hits the tailplane causing much instability quite significant such that if u are using a tractor propeller a single rudder wont work creating the need for two rudders away from the slipstream path??

There is no easy answer to that question, as it depends on the design of the aircraft. The effect of the slipstream is to induce a sidewash factor that modifies the verticle fins angle of attack.

Is there any way to actually find the path of the helix???....like using CFD.

Sure, you can run CFD and then look at a plot of the streamlines. But that is going to be a huge under taking, and require a ton of processing power.
