I haven't done much with this build due to excessive overtime. For the past 6 months I have been getting only 1 to 2 days off a month. So I am just waiting for a break where I'm not too tired to build it. So here are some pictures of what I did before the overtime kicked in and put a stop to building the Edge 540. I added yellow covering to the leading edges and the bottom tips on the main wings and the stabilizers

I just recently purchased a Revolver 70 and found that the right wing has an incidence defect from the manufacturer. The leading edge incidence alignment pin if lined up with the fuselage cut out shows a positive 2 degrees incidence and if I line up the back alignment pin with the cut out on the fuselage it registers 0 degrees incidence. With the wing forced fitted on the fuselage the right wing has a positive 1/2 degree incidence. The manufacturer has plotted in the wrong x / y axis for the laser cut out for the front locating pin. So I just got through modifying the front bore in the fuselage for the right wing. Now both wings are at 0 degrees incidence with the fuselage laying on its belly and fit smoothly into the fuselage. I am not sure if all Revolvers have this defect but I know if there is one there are others just like it.

I just glued in a 5/16 wood dowel into the original bore and relocated the bore as necessary to obtain 0 degrees incidence to match the left wing; which was okay from the start.

Installed the horizontal stabilizer today. There was a lot of slop in between the fuselage and the stabilizer so I had to add a 1\32 shim to the bottom of the fuselage in order to maintain 0 degrees incidence and lateral height. Here are some pictures.

Installed riser blocks for elevator servos, here are some pictures.

I've heard a lot of issues about weak landing gear Structure on this aircraft so I added a 3 inch by 3 1/4 sheet of .025 thick aluminum plate hopefully this is enough reinforcement to strengthen the main gear. If anyone thinks differently please let me know thanks. Here are some pictures of the reinforcement that was done I actually feel that I should have went further behind the gear about a 1/2 inch further .

Today I made some positive stop blocks for adjusting the pull pull rudder linkages. This prevents the servo horn from moving while tensioning the cables along with immobilizing the rudder during final installation. I measured from the ball link screws center to the forward bulkhead to get them equidistant while setting the positive stops. Doing the installation of pull pull systems like this is the best way to get everything correct. The positive stops are made out of 440 rods, threaded on both ends and 440 kwik links and basswood blocks 25mm Long X 15mm Wide X 10mm Thick. The rods are threaded just beyond the length of the basswood and the basswood blocks are threaded completely through the length of them, making them adjustable. I've attached some pictures of the positive stops.

I'm getting close to the home stretch on this build the receiver is installed and the servos are plugged in with the exception of the ailerons. I just have a few things that need to be adjusted on the cowl then it should be ready for balancing the CG and lateral balancing. Here are some updated photos of where the plane is at in the build. I did however modify the landing gear structure once again, and added another. 025 sheet of aluminum on the bottom to prevent the landing gear from rotating counterclockwise if in the event there is a rough landing.

CG Test For The Flight Pack
Suggested CG location 5 1/2" from leading edge at the fuselage.

This placed my flight pack in the location of the servos for the rudder and Elevators. So now I'm working on possibly mounting the pack to the canopy platform or adding the pilot figure and seeing how much this would change the location of the flight pack. So here are some more pictures.
