Prep the horns by lightly scuffing the gluing area (the part which will go into the control surface) with sandpaper or an emery board. Test fit the horn and cover plate without glue to make sure it goes all the way into the surface as shown.
- Page 4 Installing main landing gear: Attach the carbon landing gear to the fuselage with screws as shown, use blue Loctite (or other medium-strength threadlocker) on these screws. Note that there is a “front” to the landing gear and when installed, they sweep slightly forward. Locate the fairings, test fit them, and then premanently attach them to the landing gear (not the fuselage) using a generous amount of “Goop”...

- Page 10 Attach the cowl to the fuselage with screws, use loctite. Here we have added optional Extreme Flight decorative aluminum washers. Adjust and tighten the prop mount and make sure you have a small amount of clearance (approx 2mm) between the spinner backplate and cowl. NOTE: if you are new to high performance aerobatic aircraft, your motor points 2.5 degrees to the RIGHT to balance torque and prop forces.
- Page 11 Install your receiver in the position shown. If using the T-Motor power system, install the power capacitor into any open channel of your receiver as shown. We prefer to use dou- ble-sided foam tape and a zip-tie to mount our receivers. Install your lipo battery and two strong velcro straps as shown.
- Page 12 We prefer to use a cell phone with an angle-finder app as a control throw guage, but any accurate gauge is fine. Set your control throws as recommended below. We have recommended high expo for your maiden flight; if you have a favorite expo value you typically run on 3D aircraft, use it.
- Page 13 YouTube, which has a detailed section on covering maintenance and many other tips. If you need to repair your Extra 260, spare parts are available from your Extreme Flight dealer, and col- or-matched covering is available in either the Oracover or Ultracote systems.
