RE: What are you guys flying with the Ryobi 31cc.
I am also flying a Ryan's Rebel with the Ryobi 31cc engine. I have used the magneto ignition and also electronic ignition. It runs good with both. I also fly a Chuck Cunningham Lazy Ace bipe with a Ryobi 31cc. Kits are no longer available, but RCM has plans as they also have the plans for the Rebel. Both fly very well for me with the Ryobi.
