I have been looking at a thread on Flying Giants forums regarding FG84 R3. I have a FG33 R3 although I am in the process of running the engine in.

It looks like that these engines are down on power and a modification can be made to the intake manifold. It appears that they are low on power and all three exhaust temperatures are different. There is a video on Flying Giants website showing the mod being done and the performance after the mod.

Has anyone noticed a problem regarding power.

Lovely motor John, and if you modify anything, then the warranty is void.

In the 20 - 30 cc power range, this motor would be the last choice for out and out power

But, would be 1st choice for sheer sound alone without the beauty of such a machine.

Higher powered motors are 2 stroke glow motors single cylinder

Lesser power from a model motor would be 4 stroke petrol

Lesser power 4 stroke petrol 2 cylinder

Least power, 4 stroke petrol 3 cylinder.

This motor just needs the right model and careful running in.

What a beauty

If you haven't done so already, maybe you can get some inspiration from youtube:

The FG33 R3 owners on there seem to be having fun yes
