Oh I believe the 1st flight thing. Built straight and true to a known performer, balanced and powered correctly a model will fly as intended. The first flight I had on my first Stick was much the same way. I took off, it flew straight and level, I pulled up and it climbed fairly well, enough so that I pushed over the top and came buy the runway again inverted on the first pass. I was a bit more cocky back then. Ever since Sticks have been my favorite aircraft. Perfect for touch n go's, bomb drops, foolin around.
I need to build an electric stick 40 sized like yours to go along with my Gasser stick. Well done.
