Mod 1 Pinion Gear 5mm Set Hardened 13T 14T 15T 16T, 4pcs Mod1 M1 Pitch Gears RC Upgrade Part with Hex Key

Good quality, fast delivery

They're serviceable. I've lost 2 now because of the soft cheap metal they're made out of.I honestly wouldn't be comfortable recommending these for anything more powerful than a 3s system. My 6s Arrma Notorious eats through these in 3-4 packs which is unacceptable really - but 3 stars for price and since they could be long lasting on less powerful systems.

Good value so far. Grub scews will require thread lock blue/medium or the lighter type might work. Be sure to use it, or lose it.

I have used the largest pinion for my Associated RC8.2. It has worked fine thus far. I would recommend using some type of thread locker on the allen screws. They loosen up pretty easily without thread locker. Quality wise they look fine, just keep in mind that not all the pinions are solid. They start coring them out as the sizes go up. These are cheap cost wise, so that is not surprising. Longevity is a question I can’t answer as of yet. If I can remember I will follow up this review after a fair amount of time and use.

I picked these up to have some options for a Tekno SCT410 - I'm not a racer, mostly just a backyard basher. So far they are working fine, despite not having the finish quality of some of the name brands. Overall good bang for the buck.

I picked these up just to test them. I didn't want to pay $10 - $12 a pinion for "name brand" gears. So far these have held up really well. They're quiet, and metal face of the tooth isn't pitting like some other pinions I've had. The only thing to be aware of: the set screw uses a 2mm wrench instead of the usual 2.5mm.

From what I've used they seem to be durable. Tend to be a little on the longer side. I've run this brand of pinions on a few of my cars and they've held up well. Haven't put them on a beast of a system on 6s but it handles the arrma blx185 without a problem. Great price, fit and finish are good. Won't win any beauty contests but they work.
