OS91 fs in GP Extra 300 40?
Hi guys, another question in my long list lol, would an OS91 surpass be too much for the Great Planes Extra 300 40 size? It states it can take 40-52 2c and 52-80 4c... so will the 91 be too much power for the plane? Or will it be fine just with some firewall re-enforcing?

The .91 fs engine will be an outstanding choice for this plane, you will love it!!!
I had an this combo in mine and it was awsome, no need for extra buildup on the firewall, just put it in.
You will have to cut the cowl for the engine, but it looks so cool with the cylinder head hanging out the
side of the cowl like a big muscle!!
Watch the balance, and try to keep as much weight aft as you can to offset the engine weight.
