My oldest setup is a flipsky 75100 v1 with the upgraded firmware, on 14s 80amp bms battery, and has been going strong for 3 years now and counting, motor serviced and cleaned once.

Great stuff and one of my favorite things about this forum is people adding new info when they have it event to old threads.

Interested to hear the specs of the vehicle with your flispky 75100 and kunray (general size, top speed, ride feel, etc.) I have the parts but have not had the time to mess with my flipsky 75100 very much after I got the upgraded firmware working.

Also, I find it kind of hilarious how frequently these chinese companies end up implementing an upgrade or software update once a passionate DIY group does the real world testing. The heat sink was shared several years ago in this forum or the Esk8 forum and was offered from a paint sprayer company for a motor of similar size, then Electro&Co got a hold of them and sold a lot while making improvements to their version of the my1020 motors. The Flipsky controller was effectively beta tested on the Esk8 forum and updates to the firmware as well as hardware design and even the "set up instructions" came not long after some posts confirmed certain improvements on the designs.

Good observations by reneclaus11 in post #100. These inexpensive motors are under appreciated for basic single stage chain drive conversions. I have 3 of the 72V models that have performed very well for thousands of miles running on 20s and 80 amps or so. Just be reasonable and don't run at WOT for more than 15 second bursts... they do get pretty warm without cooling fins. The beefier and better EC4P motors run cooler.

I'm tempted to hook up a Flipsky 75200 to one of these to feed it some real amps, but fairly high risk of toasting it...
