The Edge 540T has an 80" wingspan airplane approximately 27% scale. It has 1200 square inches of wing area.

The Dave Patrick Edge 540T

I decided early on that I'd probably buy and fly this ARF as soon as I heard of it. I've had the DP 330L and it was a good plane. I knew this one had potential to be better. Unlike the first run Extra's, this one was laser cut, seemed to be assembeled a little better and had better design features. I never like the canopy system on the Extra. This one has a more conventional giant scale hatch system.

Assembly has taken me much longer than it should have, but that's me. The ARF itself went together very easy. My only modification has been to use the pull-pull option on the eleveator halves instead of mounting two servos in the rear. The plane has completed at 13lbs 14oz. Here's some construction photos.

From the moment it took off, I liked the plane. The MOKI engine and this plane are a perrrfect combo. If you have the 2.1, use it. I had the MOKI 1.8 and it's great. To save weight, even using the 2.1, I would put a single elevator servo on pull-pull in the middle of the fuselage. It's a super setup. I modified almost nothing on this plane during assembly. I used the "robart-like" hinges that were supplied. I put one in the vise first and tried to destroy it. It was strong. I also used the supplied Sullivan metal control horns. Rocket City might be better, but I chose to go stock. It will be plenty strong. I DID use 4-40 ball links for connecting it all up. I like them better than clevises. I used one servo per aileron. I tossed out the 2-56 rod supplied and used 4-40 on ball links. The linkages are strong and free. Right now I do have about 1.5 oz of stick-on weight sitting under the tailwheel. I will probably take it off. I'm a little aft of ideal CG at the moment, and it doesn't need to be. If I do take the weight off, that means the plane balanced perfectly with no lead. My battery and receiver sit on the tray in front of the elevator and rudder servos. I haven't flown the plane fast, so I have had no flutter. For the speeds I will always fly at, it's holding up just great. I really like this plane. Here is my equipment list: The Moki 1.8 2-stroke engine with Bisson Pitts Muffler Mejzlic 19X8 propeller. Spins at a solid 7700 RPM. This is about 23 lbs of static thrust, or about a 1.7:1 thrust to weight ratio Futaba 9402 servo on pull/pull elevator is a high speed/tork metal gear (111.1oz-in. torque and 60 degrees at 0.08 seconds) Futaba 9302 for the ailerons (99.0 oz-in torque and 60 degrees at 0.19 seconds) Futaba 9402 servo on pull/pull rudder is a high speed/tork metal gear (111.1oz-in. torque and 60 degrees at 0.08 seconds). Using big Airwild servo arm. AWESOME rudder servo for this size plane. Much faster than the JR 8411.
