Re: Hubmonster 94% efficient 7kw rated $519 Holiday Special

I weigh 200lbs. I'll have to weigh the scooter, but I can lift it myself squatting to pick it up so my guess is around 200lbs for the scooter too. Looking at gearing it for 50-55 then as around town speeds are 45, but people drive 50-55. Probably a jackshaft at the swingarm pivot point and I can red...

Looking to electrify a 150cc Chinese scooter I bought. After welding up a new swing arm, this looks like it would work well.

Re: Autocraft Lithium batteries @ Advance Auto Parts

Excuse me if I'm getting this wrong, but 3s 8ah for $299 doesn't seem to be that good of a deal for EV use.

Wouldn't this be much better than 2 of those?

Re: Looki for XR50 head tube specs.

Awesome, thanks for that link.

It looks like the race comes with it and is not part of the tube, so I'll just need to make a step just a hair shorter than the bearing height to position it correctly.

Thanks.

Looki for XR50 head tube specs.

I picked this front suspension up cheap: http://m.ebay.com/itm?itemId=251566450323 I've done some quick searches for head tube dimensions and can't seem to find any. I know I can measure when it gets here, but does anybody know of a good link to specs on these pit bikes? Specifically looking for hea...

Well the mill isn't up and running yet, but there is an excuse.

A Boxford lathe is getting upgraded with a freq drive and new controls.

Re: Time to learn how to run a mill.

Mill was $600. A lot better than the average around here ($1000-1500+). The guy we picked it up from had a chain fall to load it with and a cherry picker was used to unload. A few pieces of blackpipe made rolling it around a bit easier, hey it worked on the pyramids. I may take a community collage c...

Re: Time to learn how to run a mill.

This one is my buddies, I just picked up a CNC sherline lathe a couple months ago. We sort of have a community workshop going on between us. It did come with a shoebox full of tooling and eBay provided 3 servo motors / drivers. He also has a freq drive for it. Looks fairly tight, but he's grabbing a...

Re: Big 80-100 RC options

180KV is 26mm shorter.

Looks like the 130KV is better overall then. More motor, mass, surface area for heat dissipation, and more gearing friendly.

Thanks Guys.

Big 80-100 RC options

Is the 130kv going to be the best choice for us (vs. the 180kv) in most cases? I see the 180kv is rated for aprox .75 HP more than the 130KV, or is that just because of the RPM increase?

Thinking of picking up one of these, do these need bearing upgrades yet? I know I should add glue to the magnets.

Re: Using supercaps to support/replace battery pack

What about a couple of them in combination with LiPo to help hold the "hot off the charger voltage", or let someone regen on a fresh battery sooner, or just soak up the regen faster and lessen stress on the battery? If you put a couple in series with the batt would that help? or is a little bit or c...

Re: ES T shirt

As a continuation of Sheriff Jon's idea, What about a picture of the Earth generated by a bike wheel POV kit. That should meet the geeky factor.

Rim and tire could be captured still and Earth overlaid inside.......go to youtube and search POV or LED wheel.

Re: astro motor battery

Voltage is voltage, just check the motor and controller you plan on using for the correct amount, or others projects as some can handle more than they are rated.
