Yep, gyros are fantastic for use in speed run cars...though only a few people used them last year for some reason. If everyone used one, I bet the number of crashes would have been a whole lot less. I'm looking at getting a Futaba GY401 unit. I need a gyro for my heli anyway, so I'll be killing two birds with one stone. It's a very decent unit, so should keep LiteSpeed in check. :) They're dynamite for racing with though, like you say! Just hide it well, lol

Othello...I see what you mean, and thanks for finding those graphs. At the end of the day, I can never be sure exactly how much power will be needed to get this car up to 150, but it's gonna be quite a lot...so I guess it's better to have the betteries able to supply more power than is needed in the end. I've heard several different opinions on how much power is needed to get past 150 (some say 6hp, some 4, etc) but it all depends on vehicle weight and other stuff. I reckon the MMM will be alright, though. It's rated at 200A constant, so some bursts above that hopefully won't be a problem. :)

Brushlessboy, I'm probably going to use my Nomadio React as long as it has the range.

Anyhoo, since I'm still waiting on a quote and can't afford the other bits yet, I just bought some pipe unblocker to de-anodise the ali bits. I'll put up some pics when that and hacking-up the battery stay bits are done.

You could try and make a pack(s) using A123 2300mAh cells and if that's not enough voltage, go with as many 1100mAh cells as you can. The cells in Bosch's 36 volts power tool packs seems to have a 60A fuse and I'm wondering if it can actually handle 60A discharge. I might have to try it out and see how well they do.

Nice little pack . I have attached the graph of some little bursts. This also shows the best regen braking action as well at around 12 seconds I hit the brakes.
