Eflite Opterra 1.2m Landing Gear addition.

thingiverse

This is an add-on for the E-flite 1.2 meter Opterra flying wing to enable ground takeoff and landing with landing gear. It's designed to require zero permanent modifications to the plane, utilizing 3m outdoor mounting tape to secure the mounts. To install this add-on, you will need: A 9 gram servo (metal gear is recommended) 3/32 piano wire Small screws A Hobbyzone steering arm (available on Amazon) A Parkzone T28 nose wheel (or create your own nose wheel gear) 3m outdoor mounting tape (also available on Amazon) The mini apprentice nose gear may also work, but it's shorter than the T-28 nose wheel and might not have enough height. For wheels, use 3 leftover parkzone wheels found on planes like the Trojan, Cub, and Mini Apprentice. To print the rear mount, use normal orientation without support. The nose wheel mount requires support everywhere and should be printed bottom-up. The rear wire should tilt slightly back so the wheels are just below the notch, allowing the plane to sit on all three wheels without a battery in place. Mount the nose gear so it's parallel with the top of the black "keel" of the plane. This can also work if mounted right at the start of the black keel. If adding this add-on to the "Safe+" model of the Opterra, you'll need to install a second receiver for the nose gear since the built-in receiver doesn't forward the rudder channel out of the flight controller. To install a second receiver: 1. Connect a servo jumper with signal wire removed from slot 4 or 5 on the flight controller to the elevator channel of the second receiver. 2. Plug the nose gear into the rudder channel of the second receiver. 3. Plug in both bind plugs and follow standard binding procedure. 4. Unplug both bind plugs once the binding process is complete. Note: If you're using a DSMX 22ms receiver, make sure it's connected to slot 4 or 5 on the flight controller for proper functionality.
