Sounds like it landed the little jump on the throttle and stripped the rear diff. Gotta let go of that trigger before it touches down. You'll need to pull the rear diff and have a look. Spares I found: https://a.co/d/02AOOQS3 https://a.aliexpress.com/_m0Ds84L Edit: Just saw the bit about the metal connecting shaft. Is that the axle that goes from the differential to the wheel? Without the pins it definitely won't work. The second link I posted has some CVD axles as well. You'll definitely need to pull things apart and have a look. Check motor pinion and spur gear, front and rear diffs, and drive axles.
