Rc aeroplane engine?

Question

would it be possible to replace an electric rc plane engine with a petrol (?) one/ would it give it more power or would it just be a waste of time and money?

Answer 1

It would be cheaper to replace the electric motor with a bigger one. A lot less trouble too.

Answer 2

Yes, you can replace the electric motor with a glo plug (petrol) engine. You would need to:-

1) Re-inforce the fire wall (the petrol engine will require a stronger one). Modify the engine bearers (mounts) to take the petrol engine. Instal the fuel lines, including the filler pipe.

2) Instal a fuel tank.

3) Re-route the throttle linkage.

4) Adjust the position of the engine to clear the cowl.

5) Re-adjust the CG of the aircraft.

If you can manage the above, you have a petrol driven RC aircraft.

Answer 3

Its quite possible.

But your better off buying a petrol plane since it will be a stronger better plane and will have the correct weight distribution.

As Andy says, or try a slightly higher voltage battery. If you get one with one more cell. it will have 1.2Volts more which will give a noticeable increase. But you do have a slight risk of the motor or radio gear breaking
