Solid Quality Gear
Seems like a solid product and it does what it's supposed to on my Redcat Blackout XTE, no big issues. Gave it 4 stars tho bc the gears from this brand tend to wear out a bit quicker than some other ones I've tried. It's not like they fall apart fast, but I had one gear get pretty worn after a few months, which messed up a spur gear. Probably my bad since I didn't check the gear assembly before a few runs. If I had, I would have seen the wear and fixed it. I use a bunch of gears from this maker and they all work well, wear out about the same. I guess every gear company has their own take on metal hardness. I'd def recommend these gears, just keep an eye on them bc they might wear out sooner than others and need a tweak now and then. But if you're into RC, you prob already know you gotta make adjustments sometimes.
