Ok, so I did some research just now and the two versions that are included in the RM kit, 17955, and 17978 (Rapid Rabit, named after the Playboy Bunny carried on its rudders most of its service) had nothing to do with drones. the 7978 bird was lost late July during a landing accident, but the right rudder of 7978 is being used as a left rudder for some other Blackbird.
I did a search for D-21 drones, but the ones included in the kit might be dif. i need to check.
so I'm halting everything going on with the drone and I'm starting the cockpit of the SR-71 now.
