RE: OS PEGASUS 320 - MATCH SUGGESTIONS?
I have three of the OS 320's. Love them and they sound great. I have one in a Byron Husky that swaps between floats and wheel skis. All the above mentioned models will love that engine. Also if needed you can get scale exhaust headers for it from Ke-Leo Creations. No short pipes out the side of the cowl, but exit in the correct place.
