My Rascal 110 was my favorite plane for the year that it lasted. Make sure you fasten the battery down good. My battery was wrapped in foam and just stuffed under the tank. It came out during some rolls and unplugged, just did wide circles losing 20' at each pass until it plowed into the ground, bummed. I had cycled the battery the night before and didnt tie the connectors together yet. One of those "I'll do it after this flight" comments. Going to repair it this winter. I used a saito 1.20 with the battery under the gas tank. Balanced perfect. Just a tad to the aft end. Would knife edge as long as I wanted, beautiful. The 1.20 was plenty of power for general aerobatics and fun flying. Even saw one with a saito 1.50 that would hover for a couple of seconds before falling off.
