That’s an achievement to get up with that low torque. What propeller did you end up using? And which foil do you have?
Did you at least ask for the screw shaft?
Nop…
i was thinking i will get threaded shaft becouse of this statement but no i got shaft with key…
Thare was no option to select witvh shaft to get.
Now i modified my 3d printed fliteboard copy propeller to fit this shaft and after summer is ower i will go to maschine shope to make me a tread on this shaft.
Just above:
FreeRChobby is a manufacturer, an advantage over Flipsky, Maytech, … who are trade companies.
So FreeRCH can launch the small batches they want.
@Larsb I’m using an 8’ paddle board, initially I tried a smaller board that wouldn’t work with the amount of power I have. A Gong Allvator Rise M70, 80cm mast, and an old 1950’s 2- blade 9-spline shaft propeller 7"x4 3/4" pitch that I found on eBay. I cut it down down to 6" (150mm) diameter. The motor came with the 7.5"x7" BA prop that I modified several times with no success. I have several videos with VESC data on my build thread if anyone is interested.
The side headless screws that secures the bottom cover, I advise you to replace it with ordinary screws, otherwise water may enter the motor.
Thanks i did that allredy.
Can you provide some pictures of the motor?
What exactly do you want to see in the photos?
Motor is exactly the same as in pictures on freerchobby website.
What part of motor do you want to see.

Especially for you, I disassembled the motor and took a photo from the inside so that you can see for yourself whether it differs from other motors. If you need another photo, then just tell me, I have another motor from freerchobby.

What is the diameter for this stator? Do you have photos of rotor?
Nice! What is the stator length? And rotor diametr? How many magnets have rotor? The winding is very interesting?
The rotor has 8 magnets, diameter 35 mm. Stator length 92 mm.
I actually disassembled the motor, as I got a short circuit on the windings. As a tow, I used a rifle case, the motor overheated and water also got into it. I’m going to rewind the stator for high currents.
12 slots stator and 10 or 14 magnets in rotor more better. But is Efoil we need minimum 100mm stator. I think from freehobby the best motor is 70141
I didn’t lack power. Despite the disgusting aerodynamic properties, when using a 16s battery, the rifle case literally jumped onto the foil. Also on a 12s battery I go pretty easy on the foil using the rifle case as a tow.
The main problem with this motor is waterproofing, and this problem is much more relevant for 70141, since it does not have a ceramic seal.
