To expand on what Devo said...

A lot of times what happens is that when the plane sets down, the wheels "squash" and grab the wheel pants. If the wheel pants are solidly mounted, the plane flips. If not, the wheel pants come loose. Neither is a good thing. Make sure you have plenty of clearance around your wheels inside the pants.

Beautiful bibe. I love how you did the area behind the cockpit. Has a sinister look about it. Sort of like the bad guy with the expensive toys.
