The inductric FPV Flight Controller and DSMX Receiver combo was the second FC on the Tiny Whoop Recipe, following the original Inductrix FC. It is famous for having a completely unique and very snappy angle mode, with incredible agility and accuracy. The flight characteristics of this FC are the reason Patrick J Clarke set out to create Project Mockingbirtd, which was created to emulate the angle mode in this FC.
Nowdays this FC is excinct and there are only a few corners of the internet where it can still be found. I've raised the price here just to try to keep a few around for a little longer.
