#1AliExpress/BDUAV 6384 120KV~50 usersPositive

The most popular motor for DIY foil assist. Sold under the brand name BDUAV on AliExpress and eBay for ~$50. Also referred to as "Ali 6384", "cheap 6384", "generic 6384", "noname 6384", or "the $50 motor". The naming fragmentation is why this motor appears undercounted in keyword searches — people use dozens of names for the same motor.

Size: 63x84mm
Stator: 50mm
KV: 120 (also 150, 170)
Price: ~$50
Waterproof: No (DIY)
Mounting: M4, FD-compatible
6384 is prob the best, cheap aliexpress BDUAV works great, if not the Flipsky is great too. @patfoil
I find that the cheap 6384 120kv does the job both for foil drive and efoil, and since it is cheap, it is not a big deal if it breaks under heavy load. @bbe
Those mounts are designed around the M4 thread placements on the BDUAV generic 6384 from our friend Ali. @seagull_nz
They are the same mate. I have a FD hub fitted to a cheap BDUAV 6384. @cephalofoil
Pros
~$50 vs $130+ for Flipsky or $170+ for Saite
Adequate power for foil assist (50mm stator enough for most riders)
M4 mounting pattern matches FD accessories
If it breaks, just buy another one
Cons
Requires DIY waterproofing (epoxy coating, Corrosion-X)
Bearings need upgrading to stainless/ceramic
Phase wires need upgrade from 16AWG to 12AWG
50mm stator = ~2/3 power of a true 55mm stator
Noname 45$ '6384' is 50mm wide. @Larsb
#2Flipsky 6384 140KV Waterproof69 usersPositive

The premium mainstream choice. Flipsky's newer waterproof version with a proper 55mm stator, ceramic bearing option, and factory waterproofing.

Flipsky dropped price for $30 on their new 6374/6384. @Vitalii
I use the Flipsky 6384, there is quite a different sound and vibration to the generic 6384. Think bearings as cause of a lot of vibration and noise. Good motors. @marcoz
Pros
55mm stator (more power than BDUAV)
Factory waterproofing
Ceramic bearings available
Better phase wires out of the box
Cons
~$130, 2.5x the price of the BDUAV
#3Flipsky 65161 100/120KV42 users in assist contextPositive

The dominant efoil motor (1,334 total posts on the forum). Discussed in assist context by 42 users, typically for dual-purpose builds.

Most people use outrunners for their foil assist. @yannpom
I am exploring options for a Foil Drive-ish e-assist option... effectively a half power efoil. @juandesooka
Pros
Massive thrust for dual-purpose efoil+assist
Well-proven in hundreds of efoil builds
Cons
Too heavy for lightweight bolt-on assist
Requires proper pod/nacelle (not simple mast clamp)
Overkill for pump-assist use case
#4Maytech 638440 usersMixed

Widely available through Maytech and resellers. Older versions had quality issues; newer versions improved. Stator on older versions was only 50mm.

Maytech has a better build quality than regular Ali 6384. (Phase wires, waterproofing...) But power not enough for most e-foil systems. @Bzhwindtalker
I just tested the Maytech 6384 motor. I can fly with this wing without any problems, there is enough power, the speed is high, I am very pleased with the motor. @rttn
#5Maytech/Michobby 637435 usersNegative

The most criticized motor on the forum. Sold by Maytech directly and through Michobby (a Maytech reseller). Despite criticism, 35 users mention it because it was one of the first cheap complete kits available.

The Maytech assist motors are absolute junk. They have a lower longevity than a cardboard box in water. They are underpowered for what they are as their stator size is small. @Jezza
The last foil kit I got from Maytech was absolute garbage — controller cooked multiple motors before I gave up and switched to Flipsky. @Ewheeler
#6Saite 638423 usersPositive

Saite is the OEM factory behind Foil Drive motors. Their 6384 is the premium choice — filled with thermal epoxy from the factory, proper 56mm stator, high-quality windings. ~$170-200.

I know Saite is a great motor and in another class then the generic BDUAV 6384. @gazlinux
Foil.Drive or the Saite motors are also completely filled with thermal epoxy and have no problems! @hangloose
#7Flipsky 6374 140KV Waterproof18 usersPositive

Flipsky's smaller outrunner. Most community members recommend the 6384 over the 6374 for the ~20% extra torque margin.

Flipsky 6374 or 6384 140kv motor is easier to source. @JonathanC
#8Saite 6374 130KV14 users · Foil Drive OEMPositive

The EXACT Foil Drive Gen 2 motor. The gold standard for replicating a Foil Drive at lower cost.

The EXACT genuine Foil Drive motor is Saite 6374, you can buy it waterproofed from Saite. No magic with Foil Drive Gen2 components. @JonathanC
On original FD Assist (+, max, slim), Foildrive use 6374 130 KV 3200 W 5.6N.m to have 25kg of thrust at 3000 rpm on the propeller. @Etiennebzh
#9Flipsky 6511111 usersNegative

Flipsky's smaller inrunner. Universally negative feedback for foil assist. Zero positive opinions found. Users who tried it wished they had chosen a 6384.

Can't really get enough power without pushing the current pretty high. @Naterivera

APS 631007Quality big outrunner. Requires DIY waterproofing
Maytech/Michobby 6579 110KV7Newer motor in Michobby kits. "Cheap, powerful, works well in saltwater"
Michobby 6374 (waterproof)7Factory waterproofed Maytech 6374. Better than bare Maytech but limited
Flipsky 651216Between 65111 and 65161. Few builds
Flipsky 661126Discussed as "half power efoil" option
Flipsky 651505Mainly efoil. Rarely used for assist
6354 (eskate motor)4Ultralight. "Works well as assist... will not allow you to foil around in between waves"
5065 (eskate motor)10"Pretty amazed that it worked. Not as efficient as the 6362 but not bad."

Ultralight Assist
6354 or 5065
Only for experienced foilers who barely need assist.
Avoid
Maytech 6374 / Flipsky 65111
Underpowered stator, poor waterproofing, widely criticized. Zero positive feedback (65111).
There are differences in what is called 6384 motor, the cheapest ones have 10-15mm shorter stator and can therefore not produce the same power or torque. My advice to anyone buying a 6384 motor is to ask for the stator width. @Larsb
