Standard version (Model name – Excalibur):

• 7 flight modes (6 effective) accessed by a combination of switch SE (Takeoff, Acro and Thermal), switch SA (Acro-hi, Acro-med and Acro-low) and RS slider (Landing; overrides all other flight modes):

  • Throttle management by flight mode (max throttle = 75% in Takeoff, 90% in Thermal and Landing, 100% in Acro modes).

  • Triple rates in Acro on switch SA; all other flight modes have a single rate.

• Custom throttle curves (Curves 1, 4) to remove non-linear ESC response (will need to be tuned).

• Differential 15% (needed to eradicate negative differential associated with mechanical setup).

• Landing mode (activated by RS):

  • Custom curve (5) gives throttle from 0-90% in top half of throttle stick throw only.

  • Bottom half of throttle stick throw reflexes ailerons as spoilerons (curve 6).

  • Beep at mid throttle (transition point)

  • Coupled aileron to rudder mix activated automatically (30%).

  • Differential suppression in landing mode (negative diff applied gradually as spoilers deployed; curve 7)

• Ailerons droop 15% in thermal mode.

• Adjustable snapflap (elevator to flap) mixing:

  • Snapflap volume adjustment on S2.

  • Snapflap off when SG↑.

• Sticky throttle cut (Thr at zero AND switch SF↓) with pre-flight check reminder.

• Max power warning after 25 seconds at full throttle to avoid motor overheating.

• Flight countdown timer (reset by throttle kill on switch SF) and total model time timer

  • Timer set at 3.30 of throttle on time.

• Flight time remaining called out by short press of switch SH.

• RSSI called out by long press of switch SH.

• Speaker volume adjustable via pot S1.

• Model name announcement on start-up/selection.

Optimised Mode 1 version (Model name – ExclbrMd1):

This has all the same features as the standard version, but with a few tweaks to allow right handed mode 1 pilots whose throttle is on the right hand stick to launch the model more easily. Changes vs. the standard version:

• Adjusted sticky throttle cut incorporates 4 checks before throttle activated (activation only if Thr at zero AND Switch SE↑ AND slider LS -90 AND switchSF↓)

• Throttle up for launch on LS (Takeoff flight mode):

  • Takeoff mode automatically selected and called out when throttle activated.

  • Throttle stick has no effect below ¾ travel in Takeoff mode, but throttle can be added via slider LS to 75% for launch.

  • After launch moving the throttle stick above ¾ travel automatically selects Acro flight mode and disables throttle on LS.

  • Takeoff mode cannot be reselected in flight - only by activating the throttle cut and setting the throttle stick to zero AND switch SE↑ AND slider LS -90 AND switchSF↓ is it re-enabled.

 Audio callouts and model image - both versions

All changes are confirmed verbally when activated, and the sound files used are attached with the EEPE – simply paste them into the Sounds folder on your Taranis. A model image for the Excalibur is also included in the ZIP file to copy into the BMP folder on your SD card. Happy flying!
