Congratulations on your purchase of the 3DHS 92" Edge 540 V2 ARF!
The original 3DHS 92" Edge 540 was a legendary airframe among devotees of 3D
Aerobatics. It was beloved due to its ability to be both stable and gentle for 3D
newbies yet aggressive and satisfying for the more experience flyer. Now the 3DHS
Edge 540 has been updated to current specifications with generous use of carbon and
composites to strengthen the airframe while keeping the weight low. The cowl has
been remodeled to the latest high performance racing design borrowed from the
Edges that currently dominate the air race series. Little has changed however in the
basic aerodynamic package that the Edge is built around as it has more than proven
itself. The DA 70 or Xpwr 60cc motor are both excellent choices for the 92” Edge.

Let’s get started!
Wing assembly
1. Locate the 2 wing panels as well as the composite aileron control horns and
base plates. Use a soldering iron or sharp hobby blade to remove the covering
over the slots for the aileron horn and aileron servo mount as shown. Make
sure you are doing this on the bottom of the wing and aileron!
5
2. Scuff the portion of the horn that will glue into the aileron and secure with 30
minute epoxy. Wipe away any excess glue with an alcohol soaked rag. Insert
the ball link between the horns to ensure proper alignment while the glue dries.
3. Inspect the hinges and make sure that each hinge is seated properly. Adjust
any hinge holes that are impeding movement. Remove all of the hinges from
the wing and aileron. Mix a generous batch of 30 minute epoxy. Use a zip tie
or an old pushrod to thoroughly coat and fill the hinge holes in the wing with
epoxy. Coat one side of each hinge with epoxy and insert it into the wing
taking great care to make sure it is centered properly. Wipe away any excess
glue with an alcohol soaked rag or paper towel. Once all hinges are installed in
the wing set it aside to dry.
4. Once dry use the same procedure to fill the hinge holes in the aileron with
epoxy. Coat the protruding hinges with epoxy then slide the aileron into
position. Make sure the aileron is seated properly with minimal gap between
the wing and aileron and wipe away any excess glue with an alcohol soaked
rag. Pay careful attention to wipe any excess glue from the hinge knuckle. Set
the assembly aside to dry. Once dry the aileron movement may feel a bit stiff.
A drop of Acetone placed on the knuckle of each hinge will help to free the
aileron. Then apply a drop of Teflon or silicon lubricant to each hinge and
work it into the joint by moving the aileron back and forth multiple times.
Wipe away any excess lubricant with an alcohol soaked rag. Now is a good
time to seal the hinge line gap with Blenderm tape or Oracover (Ultracote) if
you desire to do so.
6
5. Secure a 12 inch servo extension to the aileron servo lead and install your
aileron servo as shown with the output shaft oriented toward the leading edge
of the wing.
6. Assemble the aileron linkage as shown and secure to the aileron horn assembly
and servo arm with the provided 3mm bolts. Apply blue Loctite to all bolts!
7
7. Repeat this process for the other wing, then inspect them both for taut covering
and any lifting seams that need attention with a hot iron or heat gun. Give a
good tug on the aileron to make sure all is secure, then clean the wings with a
soft cloth and Windex and set aside.Note, the wings mount to the fuselage
with nylon wing bolts.
Fuselage Assembly
8. Locate the carbon fiber landing gear and mounting bolt set in the hardware
bag. Insert each bolt into a washer, through the carbon gear and fuselage and
secure with a nylon insert locknut.
8
9. Trial fit the landing gear cuffs to the carbon gear legs and mark their
location. Remove the cuffs and apply a bead of Silicon based Goop glue
completely around the gear leg as shown. Slide the cuffs into place and secure
with tape until dry.
9
10. Locate the landing gear hardware pack with includes two axles, two locking
nuts, two large washers, two wheels, four wheel collars, two wheel pants and
four M3 bolts and blind nuts. Attach the axles to the landing gear with the
locking nuts and large washers.Install one wheel collar, then wheel, then a
second wheel collar. Test fit the wheel pant for proper wheel placement.
Attach both the inside and outside wheel collars to center the wheel in the
wheel pant. Now would be a good time to grind a flat spot in the axle to give
the outer wheel collar a better grip.
10
11. Position wheel pants in place. Use the two holes in the landing gear as a guide
to drill two holes in wheel pants for attachment. Use M3 blind nuts and bolts
to attach as shown.
