Seems like it should be strong, all metal. But its apparently junk metal. The pin in the yoke and the material around it broke. Shaft fell out, started spinning wildly. Could have done a lot more damage.It did survive a few batteries for me, but that doesn't seem acceptable.

Been thru two now in less than a week running standard 2s batteries. The weak point in the center pin that rotates the shaft on both ball joints. The center pin has bent and failed on two separate units. One lasted 3 batteries and the second lasted 1. Going to a junfac 82mm and hoping it lasts.

This may work ok for the stock wltoys 12428. With a 3s upgrade it didnt even last for 5 minutes.

Surface rust started just hours after the first run through dew saturated grass. Would need sealing paint before installing.

It came apart after 5 minutes of run time and in doing so the drive shaft flailed around causing severe damage to my truck.Cost me a new drive shaft a new rear and new sway arms to rebuild.
