Tom, my cg is right on the money.
I landed one time hot and was about to run off the end of the runway into the grass, so I hit the brakes(mine are proportional) and the thing hopped up and down like crazy. My brakes are applied with down elevator, so everytime it hopped up the down slammed it into the ground. Really beat up the gear. I am using Spring Air with 3/16 wire struts.
I'm not sure how hard I applied the brakes, and it was over in a few seconds.
Wasn't till later I realized what was happening.
It had always jumped up in the air before, higher and higher till it flops over on it's back. Happened twice now, always on a too fast landing. Usually I can hold it off until it almost stalls and then its no problem.
Was hoping for a nice simple fix. Maybe if I apply the brakes lightly when it first touches down.

Thanks
Pete Stapleton
