Yours truly was extremely doubtful about the little 1800kv Suppo motor having enough oomph to drive Mark's new foamy jet, constructed off a net plan. Well, it flew a treat and shook me rigid that the little motor provided more than enough grunt. Not sure if Mark will even bother with the ducted fan unit he was going to fit. The instructions suggest 30% flap for landing and backing the throttle off explained why, as it fast ran out of up elevator. Excellent home brew job, Mark!
