6,5Ah doesnt sound like much, but it's really not a good number to compare. I really dont understand why everybody measures battery prices in price/Ah instead of price/Wh which is really what you want. Curiously I did refer to the watt hour capacity of these packs in my post, rather than just the A...

I wholeheartedly agree. An awful lot of people can get by with a relatively short range, compact, vehicle for day to day use, with a bigger car only being needed for occasional long journeys, holidays etc. Selling this idea is tough though, as people seem reluctant to accept that a two vehicle solut...

Thanks for that, Malcolm. I'd looked at that site a day or two ago, but couldn't really confirm what the pulleys were. They purport to be 5M series, which implies that they are HTD section, but they don't look like HTD pulleys in the pictures, they look more like H section. This may be just because ...

You might be right about the cooling. The radial array would be harder to fabricate, and wouldn't have the advantages the box section has of being both nice and cheap and providing a sealed plenum for the cooling system. It'd also be taller - for the application I have in mind, being short is a dist...

I've attached a sketch of the prototype "double motor module" that I'm building to test the feasibility of using these cheap brushless RC motors. http://farm4.static.flickr.com/3265/2833474101_6fc496a0e4.jpg I've tried to make it easy to manufacture, so the main body is just a length of 2&...

I'll try and post an update on the mechanics of the double motor module I'm working on in a few days time, but in the meantime I've been trying to resolve the controller availability problem. After a lot of digging around, it looks as if I may have found a possible solution. I've managed to track do...

Interesting stuff, I'd not realised quite so many cars had electric pumps. It makes me wonder why more manufacturers didn't opt for the same solution as the Toyota Prius, with an electric motor built in to the steering column and no hydraulics or other complications. It makes for a pretty easy syste...

A popular option (if you really must have power steering) seems to be to use the electric power steering pump from the Toyota MR2. These are usually fairly readily obtainable from scrapyards, I believe, although I have no direct experience of using one.

Albright are a British company, I believe, and I've noticed that some of the bigger 4x4 and goods vehicle specialist places seem to stock their contactors, presumably for winch control purposes. A quick Google on "Albright contactor" will throw up a few UK suppliers, or you can do a search...

How far would people be willing to travel for an evening, or perhaps weekend lunchtime, social meet?

Personally I think up to about 30 to 40 miles or so would suit me, but I doubt we'll get an ideal location for all of us in the South/South West.
