My first ryobi is on an 85" Stinger and of course is underpowered.
The plane flies real well at slow speed and is fun to fly. I have a 16-10AS classic turning 7500. The jug is the slitted variety and it is a single ring piston. I know there is a lot of room for improvement and my question is where first? prop? dual ring conversion? unslotted jug? opening reed valve limiter? muffler mods? or just go fly? One of the fascinating things about the ryobi is that there are a lot of options to experiment with which is what this hobby is really all about to a lot of us. Where do I turn to for conversion parts?
