I tested out the falcon drives and they seem pretty nice. They are quiet and smooth. Freeroll is ok. Ripping around the neighborhood clocked in at 26wh/mile.
I don’t like the 4.2 ratio on them and overall I think bn drives made several better design choices. I also don’t need to go 40mph+, so I’m swapping these out for 5.5 straight cuts.
I disassembled them the other night to put them up for sale.
Right but shouldn’t the wheel and axle nut plus spacers push everything up in alignment, is that other bearing just a way to enclose it all…. questions….
The case bearing holds the rotating part that screws into the adapter, so i assume you would destroy the inner bearing much faster if you didnt use the case.
I had a marathon build weekend. Like 20+ hours working on 2 of my 3 boards. But I got done everything I wanted to.
5.5 boardnamic straight cuts on hypertrucks are on. One of the 89 tooth gears was too big for case and the other one was terrifyingly close to the edge. Dremel time. Apart from the currently questionable battery, this board is almost done.
Demonseed got a makeover. @zero_ads let me borrow his Hoyt 5” wheels and bn270’s to see what would work well on the demonseed. I can’t wait to test ride these and see how everything feels. I got the wheels to work with my bn220 hangers and there’s no chance of wheelbite with the paris plates.
My 2 lacroix builds ride surprisingly different so I set out to figure out why.
First up - flex test.
The old 7 segment enclosure results in a more trampoline like spring vs the deck with the newer 4 segment enclosure. They are pretty close and I’m not sure I prefer one over the other, but the old one is bouncier.
Next observation - ride height is the same on both boards, but I’m on 175mm tires on the naz ss and 200mm on the jaws. That seems odd. I want lowwwww on the naz.
The ride height of the m2 and hypertrucks is very similar, so it’s not that. But, looking at the offset of the truck, the m2 extend the wheelbase significantly compared to the hypertrucks. This longer wheelbase lowers the ride height.
I guess there is nothing I can do about that but I wish the HTs had a similar offset like the m2.
I just realized hypertruck baseplates are not symmetrical front to back. I think I can flip the baseplate around and extend the wheelbase slightly on the naz ss. This will lower the ride height. Stoked.
I added up how much the 18s Naz upgrade cost me, now that I have bought and sold all the parts that were going to get swapped out, and sold my old Jaws.
This doesn’t count the many hours I’ve spent on this rebuild, but it has been a fun project. Definitely worth it.
Using the new ultimate esk8 calculator to check the force and speed of various setups for my Nazare.
I want to be able to swap between the 165mm xcell RS tires and 200mm tires, and maintain >500 Newtons of force. 500 Newtons is the stock force of a lacroix naz ss with falcon drives, so that is why I chose 500 as the number to beat.
With my current 151kv motors, I am not sure if I’ll be happy with the top speed on 165mm. It might be ok. I’ll have to ride and see if I hate it toward the end of a ride.
The next ideal scenario looks like the one below. Switch to 127kv and 4.24 ratio gets me 3mph more speed, and force is very good for both wheel sizes. 32mph is where I start feeling spooky, so this could work.
I could also do 5.5 ratio on 173/175kv, and that would be perfect for both wheel sets. I like the 4.24 ratio because it growls and the 5.5 ratio screams
questions….
