Endless Sphere

Point a house fan at it when charging until you get the internal fan fixed?

It's a different track, but maybe an air powered tool to avoid the water electricity combo. But if you stick with electric, most rc type out runner motors will work under water without sealing. A geared motor technically has a rotor spinning on the axle inside the case. With direct drive the stator ...

Your basic Dr Bass style would work machined to the right size... But it prob won't be found in an off the shelf solution.

Ballistic parachute?

I was trying to picture it's dead stick glide. I don't think it's going thermal up anytime soon.

Ok.. Time to go dig them out and get some pictures...

How much are you offering for them?

I've got 3 or 4...

It probably sounds like a swarm of giant flies in flight also... Not like a falcon.

You might have it.. But the high brake/ low brake usually just refers to the voltage input to trigger the motor cutoff.

It connects to battery positive... Either directly or thru a switch. It's already going to ground inside the controller... The skinny black and red is usually full voltage out for a DC/DC converter. DON'T HOOK A SWITCH TO THIS! The high and low brake doesn't refer to low or high power braking.. They...

Like Heinzmann brushed hub motors like on a EV Global, or the big non hub motor ones?

Or, if you like Sevcon controllers....

"I too have witnessed a B-1 full afterburner takeoff, and really enjoyed the incredible noise, totally awesome, but I bet when it flies low over cattle they drop dead, my plane, they don't even look up! " I wouldn't describe it as "enjoyed"... It was more of a what hath man wrought feeling... Not aw...

We're all straying off topic, but if you want to talk noise, wait till you're living on a base under a B1 bomber takeoff path... I've been around a lot of military aircraft, but nothing matched its shattering earthquake-like roar. The Concorde was loud, but the main reason it was banned after a whil...

For me personally, the pleasure wasn't worth it in the long run. I was a glider instructor, and spent lots of time at attitude on glider flights. After flying up into enough inversion layers where the pollution is trapped in a purple layer you can't see when you return to the ground, and looking out...

So lets just shrug our shoulders and do nothing while the planet spirals into uninhabitability? The US is the second highest producer of CO2 in the world, and the highest by far per capita, and one of the richest countries in the world. Our actions as citizens of this country have outsized impacts o...

Or a 52v (58.8 fully charged) one.

You might be disappointed in the swap, as part of the difference is the wheel size... 29er lags going uphill compared to a similar power 26".

17s 1p sounds pretty weak for ebike level amp draws.

There's a bunch of way better explanations how to test it than I can give, but the point of the mosfets is to chop up the voltage between the battery and the motor at partial throttle, and switching between energising the phases instead of mechanical commutation like a brushed motor. Quick motor tes...

Another advantage of a battery in the system in addition to the stuff Chalo listed is some redundancy if the generator cuts out, or just some silent running time with the generator off.

As a flight enthusiast myself, I actually came to read about a cool electric aircraft... In the electric aircraft section... In a forum generally focused on electric alternative transportation. Your drivel was just an annoying delusional sidenote. Anyways, back o.t... that Blackfly does seem pretty ...

..... And while radically increasing the amount of CO2 in one generation might help some land plants grow where it used to be cold.... ....yada, yada,yada.! :roll: I think you are posting in the wrong thread ! ....go try one where someone might be interested in misguided ideology. Says the guy who ...

Fertilizer is plant food too... doesn't mean dumping so much of it into the environment that every waterway in Florida turns into turns into stinking toxic algae sludge is a good thing. Water is pretty essential for plants too... until its flooding from abnormal storms that crush the crops and leave...

pictures would help a lot...

Just passing on a coincidental sighting of one reference... This is not a personal recommendation.
