RPM LIMITER

The Igniter Class uses an RPM Limiter to cap the speed of your motors to the ideal racing speed. Installing this RPM Limiter is necessary for your Igniters to be made legal. This is how you do it:

BEFORE YOU START

It is a good idea to start with a good CLI dump for your board from Betaflight 4.4.2, which may or may not be from Kaack. This can help prevent a bug, but it isn't always necessary.

FLASHING THE SL RPM LIMITER

We are now using the SL Limiter, which requires you to flash a new version of Betaflight.

RPM LIMITER CLI

These are the CLI commands you'll need to dump into your Betaflight build after you get it working properly. Without this CLI, your Igniter will not be legal!
