WOULD A SAITO 125 BE A GOOD MATCH FOR THE GP LITTLE TONY?

I have a buddy with the OS91 4 stroke in his and flies fantastic. This plane really doesn't need the OVERpowering that a 3D plane can use. It's a racing plane. Now if you put a Jett 90 in it. OMG would that ROCK!

Hey guys,

this is my first time on the forum. I have just bought a new little tony and I am attempting to use my old gear and engine off a F-16P that had a nice mid air with a TONY. Great crash if there is such a thing. My question is do you think I can run my OS 120 in the tony so I do not have to spend the money on another engine?

thanks
