"Excellent set of gears, super quiet if you have a gearbox with bearings, and they spin super fast.
by Andrew T. on 08/18/2019
"works great with m120 and 30k motor shooting 410s with no problem.

"these are good gears if you shim them properly and what i found to work best for shimming my CYMA m-4 is to have one on each side of every gear and then they worked fine.

if you have a CYMA get a faster gear set cause i think these are just as fast as the stock ones

pros good gears as a replacement
even after binding them up several time trying to shim them right they still run smoothly

cons
didnt know they were going to be as fast as my stock gears

"the gears are sturdy and have withstood abuse from an 11.1v lipo+g&p120 turbo motor+m120 spring combo but the reason that im giving it a 4 star is because you have to shim the sector gear higher than normal from the spur gear or else the gears bind up and wont spin. im not sure if its a defect on the set that i bought or if it happens with all cnc gear sets matrix sells.
