Performs torque rolls, dives, loops, pop-ups and more
Convenient 2-piece wing
Designed by aerobatic veteran Mike McConville
Excellent giant-scale precision and 3D performer
Hangar 9® follows up the enormously successful giant-scale Extra 330S with another 33% scale aerobatic model with the same high quality and superior design. The Edge 540 is a favorite among modelers because of its superior 3D ability, particularly for its ease in hovering and torque rolling. Hangar 9’s high-energy Edge 540 33% ARF is a terrific precision and 3D airplane, perfect for the giant-scale enthusiast looking for the next big thing in the category.
Designed by TOC competitor Mike McConville, the new Edge 540 is constructed from durable, lightweight balsa and plywood, covered in genuine UltraCote® for an expert look, and includes a two-piece wing and stab that ensures convenient storage and easy transport to the flying field.
Most importantly, the Edge 540 is a superior aerobatic performer, flying extremely well in both sequence and 3D-style aerobatics. It flies and holds lines impressively, maintains a great presentation in flight, and snaps and shows a definite pitch break in all snap entries. It also tracks well, even in extreme crosswind conditions. 3D maneuvers are no problem for the Edge either.
Using a Zenoah® GT80, it performed torque rolls with ease. Ground handling is great, and there’s no tendency for the Edge to tip over. Slow speed flight is the Edge’s specialty with no tendency to stall. We doubt any giant-scale aerobatic customer will be able to resist the charms and capabilities of this exceptional aerobatic performer.
We do not recommend any engine over 80cc. Anything larger will void the warranty on the plane and can lead to failures. It really flies better with a lighter engine anyway. For customers who want super power, it is best to use a lightweight 75 or 80cc engine such as the 3W or ZDZ. We recommend the G-62 for sport flying or the GT-80. The G-62 will fly the plane but vertical performance is limited. The GT-80 will give good performance, but at some altitudes and in hot and humid weather the performance will be limited. You may have to change the length of the firewall if a shorter engine is used. 1" diameter hard wood dowels work very well as spacers for the engine, just cut them to the length needed.
You will need 80 oz in of torque or better for the flight surfaces. Keep in mind that the better servos you get, the better the plane will fly. One JR8611 can be used on the rudder, but if other servos with less power are used, two servos are recommended.
It is recommended to use a PCM system with gasoline engines. This will help prevent any interference issues that may develop. A computer radio is definitely encouraged, as it will greatly simplify the setup of the plane, and you will be able to use the radios features to your benefit to improve the flight qualities of the plane.
Using a computer radio, you can mix elevator and aileron to rudder to make knife-edge track straight. Also you can mix elevator to spoiler on a switch to aid in elevator and harrier maneuvers. Keep in mind the lower the weight of the plane; the better it will fly, so keep additional weight to a minimum. Also a lightweight, a high power 80 cc engine will give the best performance.
Step 7 Give the ailerons a pull test to be sure that the hinges are secure by carefully holding the wing, and pulling on the aileron. Be sure not to apply too much pressure, or you could damage the wing or the aileron.
The Matchbox option listed is a very good idea to ease the set up of the ailerons to prevent any binding or fighting of the servos. This will make the set up go much easier and quicker.
Be sure to use 1" arms for these servos.
Follow the recommendations for the set up or flutter can occur. Take your time setting this up to prevent as much fighting between the servos as possible. An amp meter such as the Hangar 9 meter part number HAN172 will be of great assistance in setting this up. Put it between one of the servos and the receiver and minimize the amp draw at all deflections of the ailerons by adjusting the control horns and servos. This is very important, as an incorrect set up here will lead to a loss of torque available to the control surface which can lead to flutter.
The wings can be difficult to put on the first few times as they are made to be a tight fit, so just take some time and if you have someone who can help hold the plane it will go on easier. Holding the blocks in the fuse that the anti-rotation pins go through while pushing the wing on will make this a little easier also.
Step 3 You can use 1 1/4" arms on the elevator servos to allow more throw without enlarging the holes for the arms in the stabs excessively. If 1 1/4" arms are used, do not move the swivel link on the elevator closer in on the elevator than 1 1/8" as stated in the manual.
You will need to clip off around 1/8” or slightly over off the hinges that go into the stab for the inside hinges, as they will hit the stab tube and not go in all the way. Dry fit the parts (assemble without glue) before using epoxy on the hinges to be sure that the elevators will install completely and get a tight hinge gap. After gluing the hinges, give the elevators a pull test to be sure that the hinges are secure by carefully holding the stab, and pulling on the elevator. Be sure not to apply too much pressure, or you could damage the stab or the elevator. Be sure that the elevator seals do not prevent elevator movement or make excessive noise while moving the elevators.
3 inch Hangar 9 pro-links are included in the optional hardware kit for the elevators, either 2 1/2" or 3" links will work.
You may need to move the battery further back for the GT-80, and forward for the G-62 and other lighter engines. Move the battery as much as possible, to try to avoid adding weight. The completed plane is very light, so if you do have to add some weight, it really shouldn’t affect performance.
Be sure that all functions work ok and are setup properly. Also be sure that the servos are not fighting each other creating excessive amperage draw on the ailerons and rudder. If the current draw is too high, it may lead to servo gear wear, servo failure, or flutter. Great care must be taken in the set up of the aircraft to prevent any serious problems in flight.
