I have just finished framing up my Great Planes Super Decathlon kit and have bought a new OS.46fx and bisson pitts muffler to power it. I also have a Saito .56 and was beginning to wonder if this would be the better engine for this plane? I have yet to drill the firewall for the engine mount so I still have a choice. I was wondering if anyone has flown a GP Decathlon on a Saito .56?

I am still leaning towards the OS .46fx but just wanted some input on if the Saito .56 would give the same performance as the .46?
