Now that I have a minute. So the first flight started with the heavier balloon type wheels. It flew just fine, but I could tell the CG could go back more. I landed and swapped to the smaller wheels which pushed the CG back to around 40%. With those it felt like it was right where it needed to be. Locked in, but slightly touchy on the controls compared to the other wheels. After a few minutes I killed the throttle and did a glide test. The glide is smooth and no surprises. I glided in for a long power off landing, and swapped batteries. With the CG good I used the second pack to work trim and get an idea of air time at cruise. Right under 9 minutes I landed at 11.1V which is a great time for mixed flying. All in all I'm very happy with how it turned out. On a windy day I'll try out the original wing.
