Long Range Wing
A fixed-wing long-range build on an Explorer LR frame. ExpressLRS 868MHz, GPS rescue, INAV. Used for slow valley passes and waypoint flights in Graubünden.
Different discipline from the freestyle quad — this one is about distance, patience, and reading the terrain. The goal was something that could cover the valley floor from launch to a ridge and back on a single battery, with enough altitude margin to GPS-rescue if the link drops.
INAV for flight control rather than Betaflight. The autopilot features — RTH, cruise mode, waypoints — are the point.
Long range wing: tuning GPS rescue for mountain terrain
Default GPS rescue parameters are tuned for flat terrain. In a valley with ridges on three sides, they'll fly you into a hillside. Notes on what to change.
Long range wing: ExpressLRS 868MHz setup and binding
First flight on ELRS 868MHz. Replaced a 2.4GHz Crossfire setup — better penetration in the canyon sections, same telemetry quality.
