Johnny, I own Jerry's ELP Javron Cub with the Titan X370, 9.6:1 pistons and counterweights. It's a very smooth running O360 based engine. I'm happy to answer any questions you may have, or if you're ever near Colorado Springs you can come fly it. I currently have a Catto 84x45 prop but considering a Sensenich ground adjustable STOL propeller.
