Cermark Pitts structual failures ?
Does anyone know of any ? Yes, I lost mine just recently. It was a pleasure to fly, and tracked like it was on rails, and now it's gone.
The batteries after crash had 75% capacity remaining, range checked excellent. I have subjected every servo, the battery pack, receiver, switch harness, and connectors to vibration using an engraving tool as a source, and I can't make the system fail. It's solid, in fact I'm now flying the Rx in my Shoestring, no problems.
But it seems to me that a while back I remember reading about upper wing or cabane strut failures. Has anyone experienced anything like this ? I'd sure like to nail the failure mode down.
