This is the first flight of the original design 3Dprinted MiG-15UTI 2-seater for 50mm EDF, which flies beautifully on 4S x 1300mAh cells. Only 37% of the battery was used during the 1:40 flight, so 3-3.5 minute flights will be fine on this pack. Many thanks to clubmate Gordon MacKenzie for the video footage!
