These are circular shaped so all the stress is placed on the small screw instead of on the actual driveshaft and then the screw just holding it.

Not d shaped
Because the ends are circular a not d shaped the torque all goes through the tiny little screw which broke easily. Don’t recommend if you like to crawl hard or go brushless. It’s a shame because the rest of the construction is solid enough to handle more power.

Metal driveshafts
They work as described. I wish they were stainless, but they work fine.
