Rc valves weren't out of adjustment much. Adjusted them and took it for a ride. Still no power till about 10k. I did notice, with the rc valves, they are opened at idle and don't close again until you get the revs up. I wlould have thought the rc valves would be 'closed' or in the low position at idle for take off ... So how should the rc valve behave?
