He was grumbling about it for the longest time, LOL.
He said he felt his landings were harsh, and that he wasn't perfectly level when he was flying. I buddy boxed with him, and he was making straight shot landings on his touch n' go passes; his flight was never going to be perfectly level because there are a couple of good updraft spots just north of the runway that will jump your plane up and down a little as you fly in and out of them, especially if you're flying something small and light, like a UMX model. It's not horrible, but it's enough to bobble the plane around a bit if you're not expecting it.
Now, I just have to get him to actually get out to the field and FLY!!!
