OK, I'll check it out when I get the engine cleaned up and disassembled. I am going to have to open it up to find out what is causing the notchiness. Its the only way I can describe it, it no longer rotates smoothly, but at a certain point I feel resistance a couple times, like a clicking that you cant hear. The engine was mounted inverted, and struck the ground on one blade of the prop, head first. I may have a bent crank, bad needle bearing, bent rod, who knows, it is so slight that I would need to mount the engine in a fixture, and use a dial gauge to detect it.
I am getting steamed up over this too, this was clearly not something I did, otherwise I would just move on as a dont do that stupid move again, but since this was caused by a defect, and something I had no control over, I am getting ticked that the engine got damaged. I can deal with a stripped servo, but the engine damage has me steamed.
