Pinions seem to mesh really well with my spur gears, but the screw and hex-driver are just too small. I stripped out the driver within one use and whenever I am actually able to screw it in enough to hold it still, I get about 3-seconds of run time before the screw loosens too much and looses all grip.
I am running a 2S lipo

Good pinions, bad choice of set screw size
Good assortment of pinions, however the set screws are so small they are extremely easy to strip out. I knew this going into the purchase though so I have been delicate when applying pressure, but they could have made the set screws bigger without impacting the gear. Without being able to apply enough pressure to lock it well, be prepared to lose a pinion now and then.

Good option for different set ups.
Normally pinions are $5 each. $12 for 4? Awesome! I'm using the 18 tooth right now. RC18T converted to RC18R. 5300kv, 25 amp esc, 7.4 lipo. Battery isn't doing so well right now. Can't get long enough runs to check temp. So for now I'll leave the 18 in. Seems to be built well. Have good gear mesh. No flaws in any of them. One grub screw each. Fast shipping. I love BTA-MALL!

Wouldn't recommend, wouldn't buy again
Set screws are too small and either strip the flats on the key or strip the threads before it's tight enough to be held to the motor shaft. Wouldn't recommend, wouldn't buy again.

thus it is easy for the pinion to be dislodged from the motor ...
They are legit Losi pinion gears. That's the only pro I have for this set.
The major con for these is the fact that the grub screws are extremely small. Smaller than the stock grub on the pinion. This makes it extremely difficult to tighten the grub screw, thus it is easy for the pinion to be dislodged from the motor shaft.
I bought these for my Losi mini 8ight T.

Losi Pinion Gear Set. Set Screws are Ridiculously Too Small to Hold Gear in Place.
The set screws are much smaller than stock and didn't tighten well. Had to drill and tap for a larger set screw. Now they work fine.

The hex screw to secure the gear to the motor ...
The hex screw to secure the gear to the motor is way smaller than the stock gear. It immediately stripped the supplied wrench without even securing the gear to the motor.

still works as long as you don't treat it like a 15mm allen wrench it should be fine
Just as advertised. Even got to use the wrench more than once, still works as long as you don't treat it like a 15mm allen wrench it should be fine.

your choice of four pinions with hex wrench made of durable alloy. These give you options and long lasting parts you can bash
