Hex Nut One Way Bearing, 12mm Hex Nut One Way Bearing Compatible with HSP VX 1/10 Nitro Engine Car Buggy Monster Truck, RC Pull Start Part

RC guys know what they do . Listed as for up to a .21 engine but using on my OFNA .26 - works as expected

Everything was great thx

Well they are the exact same dimensions as the ones for the Traxxas TRX.15 starter. However...... I tried using one of these brand new out of the package to start my nitro 4tec with the .15 and it worked for about 3 seconds. Swapped it with the starter bearing in my nitro rustler .15 and it started right up. Put the now "used" bearing in my nitro rustler .15 and it starts it albeit with a little help. Not the greatest quality which is a shame. I was hoping they would work good and be the replacements I was looking for. My Nitro 4tec is still in need of tuning however my Rustler is very reliable and starts up every time so I would say if your nitro motor is tuned and reliable when starting use these at your own peril.

Well if came and gone they did not last long bearings sprung all over the place. Nice price though wish they would have just been a little more durable

It works.

As long as your engine is tuned and usually starts right off the bat, excessive starting eventually kills the bearing. I think that's why you get 2 lol

Had to return these. Both bearings fell apart before I could even get the nitro car started.

Started my nitro engine 1 time per bearing and the needle cage shattered and the needles fell out. DO NOT BUY THESE

This product didn't last pqst 2 engine starts and the bearings fell out and it was useless
