Dear Ultrafly Customer,
Thank you again for selecting the Ultrafly Edge 540!
This famous Aerobatic airplane has been used in many international competition &
games. Its short fuselage & low wing loading give the airplane better agile maneuver
capability & allow the pilots to explore its envelop limit in the extreme flight &
competition shows. Same as the real airplane, Ultrafly has redesigned the airfoil and the
entire fuselage to create a model that is a capable in very low speed maneuvers. For a
small size (120cm or 47.2in) model, the wing loading usually makes the thin airfoil
difficult to perform good pure aerobatic maneuvers, A very thick airfoil would offer good
lift but a bit tuff in Hi-alpha approach. Ultrafly has find a good balance between the two
and create this model that can cover the two requirement properly. We hope you can
enjoy the fun in practicing your skill with this near TOC performance Edge 540!
We recommend you set up the power system with an Ultrafly H/12/09 brushless motor
(500 watt) for true aerobatic maneuvers. If you just want to have a leisure sport
experience wondering in the sky, a low cost F/18/10 with 11x5.5E propeller with
3300mAh (15C) 3S lipo would give you enough power & duration to do so!
The battery range is from 2000 to 3300mAh 3S lipo battery. A sport/aerobatic maneuver
would require 2000-2500mAh (20C) 3S lipo with a 12x6E APC propeller. For Extreme 3D
maneuvers, you should consider using a 13x6.5E propeller with 2500-3300mAh (25C)
3S lipo battery
We wish you a wonderful flying experience!
Sincerely,
Ultrafly Design Team

WING ASSEMBLY
Procedure 1
Procedure 2
Procedure 3
Try to move the Aileron up and down. Leave about 0.5-1.0 mm
gap between the wing and the aileron. This gap is also named
as "hinge line" which will be used in the following procedure.
You must allow the aileron control surface to move freely. Use
CA on the Hinge to hold the Aileron position.
Carefully remove the covering material on the holes with a sharp hobby knife.

Connect the right control surface to elevator. Then install the other
side of the elevator control surface the same way.

Use CA to glue it into position as the picture
shown. Insert CA hinges into the elevator and
its control surface.
Install the main wing on the fuselage then install the rudder fin on the fuselage for reference. Put the
model on your working table and look from the tail side as graphic shows. You need to adjust the elevator
with pin or other object to make even on both sides. The distance at "a" should be equal to "b" as graphic shows.
The angle between rudder and elevator should be 90 degree as well. Once it is perfectly aligned,use CA to
hold the elevator on fuselage.

Using tape to temporarily hold the cowling in place, install
the spinner/prop assembly onto the motor output shaft
by tightening the two hex screws on each side of the
prop adaptor. Make sure these two screws are tight
and secured as if they are not, the prop may come free
from the motor and hurt either yourself or others around
you.

Use the battery to adjust the CG location. If the battery is not heavy enough add more weight in the nose or tail
location. Set all the control surface within the maximum displacement range or you may have hard time to fly
the airplane. In you first test flight, you should set the CG at 80mm location.
It will provide a more stable flying performance. After you have trimmed the servo and radio, you may move the
CG backward for more aggressive maneuvers.
