Your probably not going to find an engine that is a whole lot better than the stock .26 you already have for less than 200 bucks. The Collari LC21B3 is a pretty beastly engine and very solid. It runs for 220 on Ace. Heres the link: http://acehardwarehobbies.com/2.2/ca...oducts_id=6041 that engine will definitely provide more power for you than your stock engine. Plus you can't go wrong with Werks/Collari they are great engines and produce excellent power.
