I flew my Edge 540T for the very first time last week. Very nice plane to fly. Mine weighed 20 pounds with a fish scale but I should weigh it again on another scale. I put in a ZDZ 60 for power. And does it have power! I had my throttle and choke servo mounted in the engine box but both got a little fuel on them. I am conserned about the fuel getting into the servo and causing a problem so I relocated them behind the firewall. Yes I installed a balsa firewall and covered it with epoxy so no fuel gets into the fuslage area. I added a slimeline showtime smoke pump to the outside of the engine box. Looking forward to my next flight.
