Hey Al..... The battery got pulled from behind the servo tray and moved forward of it, which moved the CG to about 3 1/4" or 3/8 further forward for test. I've experienced tail heavy before of course and the problems with wanting to fly till it stops in air... but frankly, I've never seen quite the issue like this one presented where the landing slope is perfect with hands off the elevator and then all of a sudden, it balloons and not just a little bit.
