Well got the maiden flight in this morning on the trainer. 3 flights in total. Flew great from the very start with very little trim required. Nice gentle flights on about 2/3 throttle with an 1100kv motor and a 10x5 prop. I only flew it for 10 mins on each battery but think I could probably get more,I will check the battery state when I get home. Glides very well dead stick. Will try and post a video when I can get a cameraman. Your suggestion of four AA batteries as ballast workedd great. Thanks once again for a great set of plans,I can see myself having great fun with this plane.
