    • Works on hobbywing mini 24
Why did you pick this product vs others?: Put this on the hobbywing mini 24 motor. Works great. Don’t forget the thread lock

    • Works like a charm!
I purchased this for a HobbyWing Mini24 set up as there are not many pinion gears with grub screws available. Worked perfectly! Fits like a glove on the HW 1621 motor. I paired it with an Injora aluminum transmission and Meus 9.69:1 for a prerunner build and it is fast! Thanks Injora!

Awful product as usual. Doesnt matter where injora comes from, amazon, ali express, dh gate, temu, etc., and direct shipping is the absolute worst. Ive bought RC parts for 25 years and injora was top notch equipment across the board. I have bought many injora parts over the years and i mean alot and it all started with their electronics , specifically the brushless esc and motor combo. I have several rc that are 95% injora from years back and have narrowed injora to buying only when injora brings out a new esc and motor. This is not a good product anymore. Quality Control i guess only happens in America. This company is very hard to do anything with on the phone or emails also. Most likely because INJORA is a chinese word from a chinese product , that just might possibly reside in china. If you were to order direct , you wont get what you were even paying for, and if its electronic ,America is stuck with it without possibility of refund or replacement. No one should just accept anything anyone says so please , its amazon , always refundable , so check ... show more
