Is there any way i can convert my rc cyclone into a gas or nitro heli?

Yes there is. Sell it. Add more money. Buy a proper nitro heli.
The minimum starting point would be a Hirobo or Raptor .30 nitro heli. A .50 sized would be even better.
You do not want a conversion of an electric heli to nitro. An electric is optimized for the requirements and stresses of electric motors. Get a heli that is optimized for the nitro requirements.

Either stay with your electric, or get a good nitro heli. Do not try to make them both the same.

I'll have to agree here. Going nitro to electric is easy, the other way around, dangerous. Electric helis use thinner components because they don't have to deal with the weight and stress (vibration) a nitro engine puts on the helicopter. It's done like this to conserve weight (just about every electric heli is lighter than it's nitro counterpart).

Like vince said, if you wanna fly nitro, get nitro. Converting is just asking for trouble.

thanks that helps
