Well the evolution .52 was a good motor it will hover at just over half throttle with a 12x6 prop and has plenty climb out. I love this plane it fly's awesome. but I have some ****ty luck. after 2 days and around 20 flight s i had a flame out 10 feet of the ground while hovering and punished my plane! thanks for the input guys now im just waiting for a new fuselage. and its just my luck, its freakin backordered! shucks!
