New Direct Drive Inrunner 65150

Yes 12s. To be honest the previous log were not that bad. 50A-60A cruising at 20-25kmh, 70-80A at 32kmh with a big draggy Gong L and 90kg. Temp never going past 43deg. The ARC200 is supposed to be 200A continuous, it really seems to be a starting issue to me. Really hard to know what happened.

At this stage I can only advise to use the 300A seal also sold by reacher and Flipsky. It is in fact a ZTW 300A seal, not sure if they modified the software so best to get it from Flipsky or Reacher. I would still have an ARC200 I wouldn’t use it with this motor but use it on a geared setup

A little package was delivered today…

Quick comparison with my 3d printed prop:

Testing soon…

Looks like low pitch and much area.
Seems to be a thrust monster

Jezza · October 22, 2019, 2:11pm

6 inch pitch, so will be interesting to see how it runs in comparison to the solas prop.

Jezza · October 22, 2019, 5:31pm

65161 on left. Flying Rodeo on right.
Going to be very interesting to see the difference in power usage now!

I thought David made the prop a 7 inch pitch.

Is your FR setup the same?

Jezza · October 23, 2019, 6:06am

Maybe it’s 7, looks like 6. The FR prop is the same except for where it fits the shaft.

michion · October 23, 2019, 6:41am

As long as its the same pitch, the difference between them will be really interesting.

Jezza · October 23, 2019, 7:31am

Yeah it’s the same. I measured it with calipers just to be sure!

@Jezza Do you have any photos of how you connected the 65161 motor to the FR mast clamp.

I got the FR mast clamp with the two 5mm alloy rods but I’m a bit lost as to how this is going to work.
I feel like I’m missing a back plate or something.

Alexandre · October 24, 2019, 11:05pm

Yes, not easy to understand at first you have to make that « plate » , it is part of the FR motor

michion · October 24, 2019, 11:39pm

Thanks Alexandre, I thought that might be but was hoping I was wrong.

This is so nice !
2 questions:

what is the mold made of
does the blade have a profile or is it flat ?

Thanks
Hovav.

I made an extra adaptor for it from delrin. Works really well! If you have a cnc or milling machine it is pretty easy.

beonwater · October 25, 2019, 9:09am

Do you make the motor mount waterproof so the water can not reach the back plate or cables? I mean do you trust on that the motor itself is waterproof around the area where cables comes out from the backplate?

Jezza · October 25, 2019, 9:27am

No the mount does not add any waterproofing. If the motor leaks then the manufacturer should replace it.

Toto44 · October 25, 2019, 9:33am

Maytech? Replace?

Jezza · October 25, 2019, 10:01am

Haha, they’ll offer another one at “cost price”…

Toto44 · October 25, 2019, 10:50am

Yeah. 5% off.

„That’s our margin, believe me“

New FR prop data:

Wing: Slingshot Space Skate 65
Battery: 12s
Max Speed: 38.6kph (average max speed was around 36kph)
Max RPM: 4184
Battery Current Values
50% Throttle (foiling): ±50A
100% Throttle: ±75A
Phase Current Values
50% Throttle (foiling): ±75A
100% Throttle: ±110A

The Slingshot space skate is meant to be a lower speed wing than the Gamma 68, but I found it faster with a higher top speed and also needed more speed to foil. What I found really strange was how much I had to adjust my stance when I changed wings.
Unfortunately I did not have the correct bolt sizes to try my small 56cm unifoil wing. I think it may have been pretty quick…
