Well boys, I think we've got a winner. I cleaned the filthy screen and she runs like a clock now. I can't believe a five minute job kept it grounded the last two times I tried to fly it. Oh well, I'm sure it could have used all new plumbing anyway. I can't remember if I replaced it last year or not. Thanks for the help guys, if the wind dies down tomorrow, I'll fly it and see. Steve.
