Flight Report
After a fair amount of trimming (I had to move the wing forward by 12mm to get the CG right) the model is flying really great for a 7 cell model. I did a 15 minute flight the other day with a bit of hooning around. It will thermal in strong lift. Just a simple fun model. I would like to make a higher powered version some time in the future.
