HobbyPlus Terranaut 8x8 Optional Metal Drive Shaft Set

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.

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.

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