I’ve got a few geared motors to sell. The first 5 have a prop and aluminium duct. The last few are the motor, with no duct or propeller.
The built in mast clamp works with Slingshot, Gong aluminium, Takuma and the clones of these mast profiles. The motor is lubricated for life with the gearbox submerged in oil, the motor side of the pod runs dry. I have tested it up to 16S with a 1500cm2 slingshot Fsurf foil and got a speed of ~53kmh at around 7kw. 12S will get 40kmh with the duct and 44kmh without the duct. The motor is good for hundreds of hours of high performance operation without needing any maintenance. There is 1.8m of 8AWG silicone wire exiting the motor (much longer than needed).

Video with power data - no duct and Slingshot Fsurf 76 wing:
The aluminium duct resonates at certain speeds, it may annoy some people, to eliminate this I recommend using this duct. 3D print it at 100% infill and add a layer of fibreglass to the struts (4 or 6 oz is good).
This is a duct I never tried, it should enable sharper turns: Fusion
$1100 usd + shipping with duct & propeller
$950usd + shipping without duct & propeller
PM me for a shipping quote - first 5 are ready to go now. Shipping should be with with DHL or UPS depending on location.
Also, if you want all the components to build it up yourself or a PLE040 5:1 gearbox PM me as I’ve got a couple spares. If you have any questions comment below! I also have some spare brand new maytech v2 remotes - $110usd each. I have had a change of plans and therefore I am selling these motors at pretty much cost price of materials, give or take. There is no warranty offered for this reason and also due to the nature of DIY builds. The motor will not disappoint, it has great power, flawless reliability and is easy to open up to replace seals or bearings which may be the first components to wear out years ahead.
**In the current motors there is no cir-clip between the bearings and seals, there is instead a spacer ring.
