This is from an email that Ken sent out today:

Model Warthog with miniature twin turbo-jet engines. You can plainly see it start to shed parts; the canopy goes, and parts of the split-ailerons. I have absolutely no idea how he saved this airplane; the wings are flapping like a birds, and the vibration had to be horriffic. Heart-stopping.

This is a video of a huge A-10 flown at Florida jets the other day. It has two turbine's and is extremely scale.

The plane starts to come apart in the air from flutter.Change the picture to full size to see it better.

How he got it on the ground in one piece is a mystery. The wings had to be extremely strong to withstand the vibration.
