Used this in a brushless Traxxas blast build to replace the awful plastic coupler. Held up great until the boat caught on fire, was one of the few parts that remained intact.

Well made... I ordered the wrong size, but you never know when I might use it!

Worked perfect for my application. Connecting drive shafts on a small motor.Used to connect 2mm shaft to 1/8 shaft. I had to bore out one end to .125 to adapt the product. Simple fix to get my unit going.

Do not buy this. This is a plastic piece AND the dimensions are NOT accurate. The 5 mm side is actually 4.8 mm so a 5 mm rod does not fit. Chineseum typical.

i drilled the shaft hole to 1/8 all the way thru coupler .I connected one end to a dremel tool grinding stone and tightened set screw. I used a 1/8 hardened wire stock from hardware store a made a perfect extension that i needed to get inside a gun magazine to get rid of a ruff spot .

Perfect fit for the cost. I used it to connect prop shaft and motor for my Billing model boat.

Using this for a Proboat Jet Jam brushless motor mod, it's a drop in replacement for the stock part. Fitment was perfect.
