The theory is right.
Then again plywood is not light. For better utilization of thickness use foam.
Either way don’t forget about localized stresses/buckling with too thin layer.

this has 18 18650s in it. 10 pounds or less is totally possible, might be able to get two more cells if some other weight was shaved somehow.

How much does the rona roller weigh in at, for reference?

Just to be pedantic, that’s a picture of a split scimitar winglet on a 737. Not a normal wingtip

Coincidentally winglet is a great choice for this project as winglets like the one in the photo are predominantly used by short haul airliners as they improve climb performance at the expense of induced drag. This trade off is only worth it for the really short routes. And that’s why larger airliners use raked wingtips.

Been busy this week, so wanna share some thoughts.

Currently watching videos about stm32 programming, bc I wanna move further then good old avr thingies. So yeah, the brains and remote of the wingtip will be stm32-based. The data transmission will be organized on the HC-12 modules, that work flawlessly for me for a long time with no issues.

The antispark and receiver are going to be on the same PCB, which connects directly to the rear of the VESC. This design leads to a good space-management, very clean look and the wires floating around minimized.

Could you make like a balsa or foam mount, and then just skin it in CF?

That seems like it might be a pretty easy DIY.

It does look awesome.

Do a kick flip.

Are those the ride unlimited hub wheels?

Do they sell them separately?

Yes, here you go:


Not cheap tho. 220 euros per wheel.

Wow.
Thanks.
That is pricey as hell.

I will keep waiting for you to post a video of the kick flip :wink:

Guys, i need suggestion on the battery connector. Xt60 seems an overkill for 1p p42a, so… Deans or xt30?

I would use XT30 over a Deans connector but if 10 lbs is the goal, you better just solder and heatshrink and seal because it’s less metal. And I’d run 16AWG

PSA:
When soldering on a live battery, remember to completely finish, wrap, and seal, one wire before taking the tape & insulation off the other wire.

And oh yeah tape the ends of EVERY wire that you’re not CURRENTLY working on.

It’s not overkill, it’s being smart.
