My tachometer tells me this motor is 145 kv
Have you managed to get up on this motor?
I just received it, maybe Iāll try it this weekend.
N tacho = Xkv x (number of cells in series x indiv cell voltage) = Xkv x applied battery voltage
Xkv = N tacho / measured battery voltage
Not using the measured battery voltage could increase the motor kv by 24% (1/4.2)
Before measuring, I switched the battery to storage mode with a voltage of 3.8 v. per cell, 145 kv is the correct data.
So Iām getting 167Kvā¦
10S battery at 39.4V is getting 6614 RPM

my motor was doing this 6384 120kv. i used a slightly smaller prop with less pitch and i never saw it again. there must be too high a load on it, that causes the timing to desynchronize.
Latest feedback from customer, Maytech MTO6374-150-WPC waterproof motor: āat first I thought this doesnāt look like waterproof motor, NOW I see it is waterproof and so far the paint coatings on inside are better and very little rust formingā

This is where you show up and just make public you know absolutely nothing at allā¦
I can tell you right now that the coating on the maytech motor is weaker than the official foil drive motors and the motor has less power.
Simply put itās just an inferior product with a lack of thorough design and testing.
Nothing pisses me off more than companies making non data backed claimsā¦

Trying to find out where I can order a Saite motor. Please drop a link.
Google is your friend (thatās how I found it)ā¦
Alibaba will be your friend too 
Hello I bought a Maytech-Kit assistance aluminum DIY, motor 6374 waterproof 3.5 KW, controller VESC 100A V6, remote control waterproof MTSKR1905WF to make a copy of the foil drive assist.
i have a foil drive and want to make one for my daughter to ride together .
and when I connect it to an FDA 28-volt battery, the motor starts running at 50% and nothing before that. why?
it doesnāt seem very powerful I guess the FDA battery is not calibrated for this motor .
I saw in a video from the FDA team that their motor was limited to 1850 watts to preserve battery life.
Sounds like you need to calibrate the remote in vesctool. flipsky has a video for the vx3 not sure if maytec has any instructions but should be similar.
Can you tell us what mosfet is used? Thanks!
I am looking for the performance that is possible from this vesc
What motors do you like in which scenarios? Iām an experienced foiler but noob foil builder . Goal is a faux foil drive with a 12s pack
I havenāt got the maytech working yet. I have really efficient props coming this week so weāll see if it works with them.
I waterproofed a battlehardened flipsky 6384 140kv. Itās a very strong and capable motor. But I did need to cut and thread the rotor.
The waterproof saite 6384 120-140kv will work well with 11s and that means you donāt need to mess with epoxy.
