Mike,
You're very likely right about the CG. The two I've flown have both been Beginners planes. The first was Yub, Yub's, the second was a guy named Brett (ahfoo on RCU).
Not sure why Yub (David) wound up with the Tiger as his trainer, but IF he gets his prescription for glasses, I don't think teaching him on it will be a real problem. He says July before he could get an eye appointment. [

Brett had flown a bit a few years ago, and I first took him up with my Four Star on the Buddy Box. He did quite well and had expressed wanting to progress to warbirds as soon as possible (without being pushy in the least), so I suggested the 4* or the Tiger 2. He went with the Tiger.
Both were likely nose heavy because both David and Brett used nose weight to get to the "recommended" CG. When I finish rebuilding the one given to me, I will experiment with it.
Thanks,
Dennis-
