Bme 55 Xtreme I think its called will haul a plane around liek crazy. I wouldnt be completely positive about those Yaks being so light until yuo se one. Don't get me wrong, but I would wait and thats a pricey plane so maybe it does weigh 15 lbs. DA50 is great. It really dpends on how a plane balances out. Id like to make something for a plane liek take a few pieces of metal and get the weight the same as the motor I am using to determine a balance point. Try a BME and im sure you will love IT!!!
