Endless Sphere

This guy, Kotaro Horiuchi, pretty much perfected the submerged two foil power setup, where well designed alignment of the thrust makes it naturally lean into the turns.

Nothing new under the sun as the saying goes...
Basic aftermarket surface piercing set up.

The Hobie version they made for a while.. The yellow L foils flip under the boat in use... You did NOT want to run that one aground!

It is an amazing feeling when you start sailing faster than the wind speed in smooth water... Magical. Some of the new boats can do 2.5 times the wind speed in perfect conditions... Going 20kts in 8kts of wind creates this weird sensory field that makes your brain reel. Just watch out for stumps and...

Some surface piercing type.... For a while Hydroptere held the outright sailing speed record and the measured mile speed record. 078f950f24518ebfcb689367d6449d43.jpg Large_2012lHydroptereDCNS9Copyrigh_Francis_Demange.jpeg That was an incredible feat, as most drag race sailboats are tiny and fragile,...

It could totally be that too...a quick continuity test should show what's up.

It might depend on your system, it needs 5 volts in... And its looking for something near 5v out as the cutoff, but not less than a volt or so, as zero makes it think the brake is disconnected.

More and more of the three wire ones are Hall sensor type, and won't work with cheap generic controllers looking for a two wire signal. The plus for manufacturers is they're harder to bypass...the whole system shuts down without the brake wires plugged in. The plus for users is nothing... It sucks i...

It turned like it was on rails regardless of tilt... You could feel the g forces trying to fling you out of the boat in high speed 180s. Edit... But if you meant did heeling induce a turn, not noticably, esp compared to a regular keelboat, where when you heel there's a big offset between the drag of...

Here's some pics of some test boats for the next Americas Cup.... When they change directions, all three are temporarily swung down, then back to two most of the time. T foils rock 👍 1552946497930.jpg vbXPwYRQyO0YJN0Lpvuw_Emirates-Team-New-Zealand-launch-AC75-America's-Cup-boat-in-Auckland-1280x720....

Surface piercing foils are usually designed for a narrower speed range, and flatish water conditions, which on say a powered ferry on a river is fine. Then you get major wake reduction, and relatively simple construction. They're usually are designed to self limit the ride height, with ever smaller ...

If you're just running the BMS for charging it's not an issue... But as people have said, starting with quality matching packs helps a lot. I ran matching packs in series for 20s, then paralleled them with roughly matching capacity packs for the range I needed for a particular ride. PSX_20200110_105...

I'm interested.. I'll pm you

It's close to this one, Futr Beta, but the seat tower is a little different.

Random Google ones...

I like to just jam my grip against the throttle when I want it to stay on... So great on cold mornings riding with your hands in your pockets 👍 If you tap where it's says KVID0020 it will take it to YouTube instead of the weird viewer here... It links to a couple of other vids too... Kvid0021 has a ...

It's not just metal pieces., It's magnets, alternating polarity in a pattern. Some discs won't work with some controllers, or need to be mounted reversed to the arrows on the disc, and you can't just hotwire it together as it wants the pulse pattern. Sometimes there's a plug coming out of the contro...

My bad..I meant backwards so the clutch is engaged..

It works with a gear motor also, as long as you spin it forwards.

A quick field test is to short two of the three phase wires together and hand spin the motor. The motor starts cogging when the windings aren't damaged... If the motor still spins freely the winding are damaged internally.

During testing I laced one motor up to a 24, a 26, and a 700c, and it got noticably worse in performance with each larger size wheel. I think you will notice a difference if you step down a size, as long as you're not dragging the cranks.

With the Motenergy type, another difference is they are typically inrunners, with the coils on the outer shell, where they cool better. Hub motor has to have the coils inside with the outside spinning, so the coils don't have as good a thermal path to the outside.

In my experience that's not the case. In power applications, esp where there's codes to follow, crimps are better. No solder wicking up the stands making the stands break at the flex point, no uncured flux eating at the wires, and no solder melting off during overheat situations, and full conductivi...

One thing about those blocks, some were comparing them to the bus strips in a house power hookup. It's totally not the same... You would have to override every circuit breaker and run everything at once in a house to get the bus to heat up at all. That's where the looseness over time comes from. In ...

It's better conductivity. That's what you don't really want to use If you can avoid it... Pure nickel is better. More conductive, no rust (the plated steel rusts thru from thin spots in the plating in wet conditions), less overheated strips melting thru the heatshrink on the cells.

Then you'll be getting lots of pedal strikes as the bottom bracket will be closer to the ground. Just wondering, are you actually going to be trail riding, or making a pavement burner?
