Yep... what he said.
BUT...... DO NOT say you are fixing a Cermark. There's some bad blood there.
Also... I'm fixing a Tam's F16, and one of the parts I needed was a canopy. A friend of mine got it from the company who built them for both Tam and Cermark. This was just last year... but for the life of me, I can't remember who that was. I will try to find out who that was.
