A-7 flight report

Well, after 3 hand launches throwning hard, very hard, the poor little gal struggled to gain altitude and about 150ft. out, it tip stalled and fell to earth.
Luckley I was flying over 3ft tall wheat and it only got to a breath taking 15ft in altitude! Just couldnt overcome the power to wieght ratio issue. May try to shoe horn a 40 mm in her. Thats all for now.

Bummer, I thought it may be too heavy for that little motor being 5mm foam but a chop and swap will get her going no worries.

I suspected that might be how it would be. The AEO 30-10 fan with the new venturi impellor might give enough oomph to keep it in the air if you cant squeeze in a 40mm fan, but it may still be quite marginal.. Or a KP 32mm on three cells would do it for sure.

Well worth the effort as now you know 1. How to build another, quicker, from lighterr materials, 2. That the power setup isn't up to the task at that weight. 3. That we are all rooting for you!
