Went flying again yesterday and had a GREAT first flight. Really enjoyed getting it up in the air and had the whole field to myself. Then on the second flight the engine suddenly quit and had to deadstick it in. I noticed the engine wouldn't turn through the compression stroke at all so I popped the top off and there were metal shavings on the piston. It looks like the bearing wore out so I have to replace them before playing again. Hopefully I can get it back up ASAP as it felt so great to be back in the action!
