RC in no way warranties its aircraft against flutter. We have put these aircraft through the most grueling
flight tests imaginable and have not experienced any control surface flutter. Proper servo selection and
linkage set-up is absolutely essential. Inadequate servos or improper linkage set up may result in flutter
and possibly the complete destruction of your aircraft. If you are not experienced in this type of linkage
set-up or have questions regarding servo choices, please contact us at info@extremeflightrc.com or
770-887-1794. It is your responsibility to ensure the airworthiness of your model.

  • Page 4 • 1 x Extreme Flight 4” double offset aluminum arm for the rudder (tapped M3) • 2 x Extreme Flight 2-wire MPX Multi Plug (an quick and easy way to hook up wing servos) • 3 X 24" Extreme Flight 20 AWG Servo Extensions (2 outboard ailerons 1 for throttle).
  • Page 5: Let's Get Started

    Let’s get started! 1. Locate the wing panels/ailerons and horizontal stabilizers/elevators and associated hardware bags. We will begin by hinging all of these at one time. I strongly recommend 30 minute (or slower curing) epoxy for installing hinges. I have found it easier to apply 3-5 drops of glue in the hinge hole and then using a toothpick, or similar, spread the glue around the sides of the hinge hole.
  • Page 7 2. Install the control horns for the ailerons. ***PLEASE NOTE*** There are three DIFFERENT control horns for the ailerons. The 106" Edge construction allows for three aileron servos per wing. Each control horn is drilled different for pushrod attachment. This is to keep control horn/pushrod geomentry consistent with all two or three servo positions.
  • Page 8 3. Install the aileron servos and orient the output shaft of the servo towards the leading edge of the wing. We are using the Extreme Flight 1.5 inch servo arms for the ailerons. You will notice there are two types of ball links included: one standard ball link and one with a built in riser.
  • Page 9 5. Rudder installation. The 106" Edge includes hinges and hinge rod to make the rudder removable. Be sure to take your time installing the hinges. Dry fit everything first! Be sure to orient the hinges consistently on each side/surface. Dry fit the hinges and install the hinge rod. Adjust hinge slots as necessary. Once satisfied with hinge fit and placement, apply glue to hinge slots.
  • Page 10 We highly recommend the MKS HBL380 or 599 for this location. A double 4 inch Extreme Flight aluminum servo arm will provide plenty of travel while maintaining the best mechanical advantage and servo resolution. Two control horns are provided for the rudder. The slots for these must be located and opened with a sharp hobby knife.
  • Page 11 Install the rudder servo and center the double servo arm. Assemble the ball links and the pull-wire ends as shown. Thread the pull-wire end in the ball links four to five turns. This will allow room to tighten the wires after pull-pull wire installation is complete.
  • Page 12 6. Next we will install the main landing gear, axles, tires, wheel pants and wheel cuffs. Use the provided bolts, washers and nuts from the main landing gear hardware kit to mount the carbon gear to the fuselage. 7. Install the landing gear plate cover over the mounting nuts. Glue in place with Goop style silicon glue.
  • Page 13 9. Next we will install the tailwheel. Locate the tailwheel hardware bag. Notice the included ball link. This will be installed in the bottom of the rudder for the tiller wire. It is good practice to remove all the set screws and bolts in the tailwheel assembly and reassemble using blue Loctite.
  • Page 14 10. Next we'll install the engine. There are laser marked locations to drill if using the DA-120. There is also a laser scribed cross to use a template for other engine makes. Drill for 1/4x20 mounting bolts at the proper locations. 11.
  • Page 15 12. The throttle servo is mounted to the bottom of the motorbox in the cutouts provided. Use a rotary tool the open the bottom of the cowl to fit the mufflers and to provide an exit for air. A pipe tunnel is provided along with vent covers for the bottom of the fuselage.
  • Page 16 Control Surface Throws High Rate: Ailerons – 40-42 degrees Elevator – 55-60 degrees Rudder – Maximum throw available without interference High rate controls typically use 50-75% exponential Low Rate: Ailerons – 15 degrees Elevator – 20 degrees Rudder – 30 degrees Center of Gravity The preferred CG for this plane is at 5.5”...
