Jumping servo - available?

[mefistotelis]

All the jumping drones are ultra easy to repair. I really love it. And it's easy to do it with kids - they can help ie. by inserting the rear leg pull lever while you are forcing the springs into correct positions.

But I haven't seen all the parts in "repair kits". In particular, I'm missing the jumping servo. Whole mechanical part is easily available, but not the servo.
I already have two drones which can't jump because the gears inside the servo are damaged.
(I bought a pack of damaged ones, and am slowly repairing them)

Looks like I'm not the only one having trouble with this gear:
