Everette,

I pulled the motor this morning and carefully inspected it and do not see any irregularities. Bob mentioned he would loan me a 110 speed controller to check the motor so I may do that first. I will call Castle tomorrow. It is amazing how that burned smell permeates everything. It was interesting that the failure occured very early into the flight and in level flight (inverted) steady at about half throttle. I completed the clover, hammerhead and was just about to start rolling in the 3 of 4 reversed roll when the failure occured.

Thanks,

Ray
