I wheel the 'buddy board' out of the hangar again, in an ongoing effort to get T-motor's ESCs communicating with their U7s: currently (geddit?) about as easy as getting Presidents Trump and Zelensky talking.
Wheeled out of the hangar at the same time, however, is electronics guru Phil... who not only lives locally, but has also done sterling work on my drones in the recent past.
Should he not succeed in getting the rotors turning, I've a valid excuse to throw in the oily towel.
