Well I'm doing the repair, but it's not my plane. The Longer version is an Engine came back from overhaul, put back on the airframe and the pilot wanted to do a couple short taxi test with the wheel pants on(non-vented). Don't do that! We were also trouble shooting brake leaks and rudder travel issues(which prevented the brakes from being fully actuated), so during the taxi test the rudders were disconnected. This aggravated the braking required to keep the aircraft centered on the runway (instead of using the rudder force) so a couple factors added into a problem, no single point of failure. The builders out there build such tight wheel pants they act like ovens. Read the Canard pushers, specifically CP57,CP70. Don't do taxi test with wheel pants on (and if you're a new pilot to the Canard type aircraft, think twice about putting them on during getting "comfortable" with the plane). If you do put on wheel pants, wrap the gear leg with fiberfax and aluminum tape, put on the heat shield and vent the pants so the hot air has somewhere to go.
That should keep your gear leg from melting.

, gear leg overheated (melted at the point the aluminum heat shield was RTVed on.) The brake disk was almost touching the aluminum shield (about 1/16" clearance). The space used to be about 1/2"+ gear leg is definitely distorted.
