helped a friend put a dave patrick extra together with a bme 44 and it is the best flying airframe for your motor. we came in at 15.8 lbs using two rudder servos. the plane went together very easy and flys awsom. it will do any move in the book. if i wasnt already flying 2 35% planes i would put together this combo. if i were buying new i would use the bme 50 but the 45 will do it all
