It's a chip thinghie of some 2/2 mm . Will need a drop of glue to disable it but then 2 things will happen .One: the inertial system will be contradicted by the baro (accels and thr tells it that is going up , baro that is staying ) . Should generate autoland sequence if the divergence is too high.Second , the Baro will remain probably permanently disabled . Can be defeated by using a hacked firmware but the ideea was to eliminate the stupid casuals , the smart nuts will run one of these anyway :
