Good morning, I'm Italian.
I have the kit of Top Flite Giant P47 to build.
I'm interested to mount on this model the Magnum, ASP or SY 400 5 Cylinders 4 stroke radial engine, but I never see to run these engines.

Someone had seen to run these engines?
I wanted to know if these engines is good for to have good flight performance on the P47.

Thanks,

Massimo.

Hello Massimo,

The Magnum 400 is 8.5" diameter. Will it fit inside the cowl?

Here is a video of my engine on the test stand, first time running:

Hi and thanks for your answer.

From your experience with this engine, do you think that the power is good for the Top Flite Gian P47 or is too much little?

Exactly what propeller and how much RPM do you have on your engine?
On what model do you use the engine? (do you have video inflight?)

Thanks,
Massimo.
