Holy Cow! That was an amazing flight. Fast and tight. I'm guessing you're not new to RC aircraft. Where are you at in the ROK? I'm ex American military and I am familiar with Wonju, Seoul, and Osan. If you happen to to be on the street in Osandam (It's been a lot of years, I can hear it in my head, not so sure of my spelling.) Back then, an adjima had a cart, where she sold yakimandu on the street. Cooked it up right there in front of you. Best on the planet, as far as I know.
That was a lot of years ago, but I really miss authentic yaki mandu and bulgogi. Heck, it was the adjima on the base take-out kitchen who taught us to put American Cheese on Ramen. Shoot. I'm transgressing again.
Awesome plane and awesome flight! I can't wait to see more!
