Corwin, thanks! I want to get a set of gear from Graphtech. Can you post a pic with the gear on the plane?
RC-F, I had similar experiences. I had a dead stick on one of my best contest flights with the Venus. I spent the whole contest behind the pits with some guys trying to get it running right, couldn't seem to get there. And this is with guys who have been successfully running pumps in contests for years.
