DLG - Pro template for F3K
DLG is a competition-ready template for F3K discus launch gliders with 4 servos. It's based on the popular OpenTX version.
Enhancements in DLG 2.1
V 2.1 offers easier adjustment of pitch-trim and camber.
- The elevator trim is used for all pitch adjustments, including brake compensation.
- When deploying brakes, the elevator trim is repurposed to adjust the compensation curve. This means you can quickly optimise pitch trim across the full range of the brakes, whilst flying the model.
- Camber/reflex are quickly adjusted using the throttle trim. No need to dive into the menus!
At a glance:
- Quick setup
- Customisable layout for different tx's
- Launch height callout (vario rx required)
- New in 2.1: brake-aware adaptive elevator trim
- New in 2.1: easy camber adjustment via throttle trim, per flight mode
- In-flight adjustable diff
- Auto suppression of brakes when exiting Zoom, with sound alerts.
- Setup guide and programming reference
- Sound files in English and Italian.
The template includes a special 'CAL' mode for precise matching of control surface travels.
