I’ve updated my spreadsheet, v1.9 on the tab title.
- Throttle-based HNOTCH section (added some time ago)
- RPM-based HNOTCH section
- New MOT_THST_EXPO calculation in the copter 4.0+ section
- Old MOT_THST_EXPO calc is still in the copter 3.6 section for comparison
- Added a couple of the newer Solid State batteries
Some of these calcs are approximations and will need adjustment based on real data in your logs.
The new MOT_THST_EXPO is based on some early/incomplete results from the expo LUA script, but a key feature is limiting the expo value more for very large props. The new value should be close enough and safe to use.
The old formula is in the 3.6 section for comparison. Keep in mind the old formula was somewhat arbitrary, so it wasnt necessarily “right” but just an approximation. This makes the new formula a slightly different approximation rather than right or wrong.

If this iteration proves useful, I’ll work on getting some of the updates into MissionPlanner Initial Params.
