BTW you might get a kick out of this but with all the problems we had with the other 2 aircraft flying that day, the kid's and the instructor's biplane, we totally forgot to check the CG and took off without ever checking it. It should have been ok considering it was built by an experienced r/c pilot a while back and I bought it second hand but hey you never know. Anyways she took off like a bat out of hell and works great. The biggest problem I think would be that the engine may be a little too big for me to start off with and will take a little getting used to for landings. It's not easy to put her down because even at idle she's not slowing down too much. Flying it in circles and straight it only takes about 1/3 throttle so it can really move. But I'm really happy with it. I think I'll name it Old Faithful LOL
