This plane is low on wing area for it's weight. This isn't necessarily a bad thing pending how you want to fly it. If you want to land it slowly, I would be careful about adding any unnecessary weight for the already suffering wing area to handle. If you are looking for a screamer, and if you keep it around 10lbs, I'd get a 20 that is happy running very high rpm's all day long, and have fun with it. Zenoah's are known for being happiest spinning higher than 'normal' RPM, but I am sure the Syssa, RCGF, DLE or others may do just as well for your desired flight characteristics.
