I own both of them
2500km on Maytech 6374 - replaced the bearings, but magnets and everything else was fine
500km on Flipsky battle hardened - still performing good, can’t say anything bad about them
So, I think, it’s only about the price and availability
No complaints about them. The strain relief on the sensor connectors are quite bad, but it’s nothing important.
You can find the motors for pretty cheap on AliExpress btw, looks like as low as $66 each. Shipping adds an extra $18 each though. This was the HGLRCTech storefront, which seemed to be the parent company of Flipsky or something like that.
so what you’re saying is you thought about a motor everyone has known and loved and considered buying some crap with loose magnets that required this whole battle hardening thing to happen in the first place?
+1 to this.
The FS battle hardened seem promising but why risk it when you can pay a couple extra bucks for the Maytechs which are renowned for their quality.
This isn’t necessarily true for everyone. I had just as good luck with old flipsky motors as I did with TB motors.
Either way tho, the “battle hardened” line is flipsky’s first motor’s designed and produced in house. The other were all a diff OE. Does that mean it’s better or worse? Could be either really, but personally I’ve heard near zero complaints about the new motors, non the contrary mostly positive remarks.
And on the flip side, not the flipsky, maytechs reputation has fallen quite a b with all the overheating issues. Especially the 96’s which were supposed to be the best motor ever, but the 74’s definitely suffered from the same issues.
Had this weird issue occur today while messing with my motors, they seem to gain resistance and clicking at certain angles.
Both are brand new motors.
Anyone have an idea?
sounds like something scraping on your stator. probably a loose magnet.
Fucking bitch lasanga.
Is there anything I can do? Or should I just return them.
take it apart and see what’s in there.
any signs of rubbing or wear on the stator, sensor plate, or windings? Check the stator for broken wires.
Don’t want to buy crap at all!! Thus, the reason for my post. Just want to get the best motors for my build. I will spend top dollar if need be. I want the best
turn the bearings with your finger and see if any of them feel gritty.
Actual top dollar? There are $200, 300 motors that are more reliable?
