Anyone have experience with the Injora portal axels for SCX10II?

They look enticing. All metal, $100, and no offset pumpkin so I won’t have to mirror my forward motor mount. Injora has been good to me with my SCX24 build, but I wonder if they’ll hold up with something as complex as 1:10 scale portal axels.

I used those axles on my Baja Bug build (until I replaced them with Capra axles). See my build thread in this forum. They are great axles, but if you're using a powerful motor (brushless fusion) and have a 3-gear transmission that doesn't have a slipper plate, expect to start stripping gears. I've broken and/or stripped a couple sets of portal gears.



Most recently, I stripped the front ring & pinion, which is what made me decide to switch to using Capra axles. The replacement internal parts (gears) you can buy are not great quality.

So it really comes down to usage, and how powerful your motor is, and whether you have a "fuse" in the system that will let go before it starts stripping teeth. If you can live within those parameters, then they are a great option.

Get some name brand internals and should be good!

You can probably use "name brand" ring & pinion gears, but the portal gears (top and bottom) are the same size (1:1 ratio), and all the name brand portal gears I've seen are for axial-type portals, where the top gear is much smaller.

I'm going to be using my Injora portal axles on a Jeep Wrangler build I'm doing, but I'm also replacing the all-metal amazon 3-gear with a normal plastic 3-gear transmission, because it includes a slipper clutch. Hopefully that will reduce the tendancy to strip gears.
