A couple of years ago I ran in a 1000 lap race together with Jilles Groskamp, Markus Möbers and Peter Meurs. We ran a 15 turn motor and only had to change it once (after about 700 laps one of the brushes came unsoldered). Nowadays I would probably run about the same wind but then use a V2 style motor with endurance brushes so we could do the whole distance with one motor, or alternatively run a brushless. Make sure the motor is not too fast. It is all about consistency.

As to the batteries, you should look into building quick battery change system. We managed battery swaps in about 4-5 seconds with one super stop that only lost us 3.5 seconds on the track! We averaged about 10-11 minutes for each pack. Moreover Jilles did the fastest lap while running our last battery

About 13 or 14 years ago they ran an off road enduro at my local track. I think it was 2 hours or something. I didn't run in it but I remember seeing a couple guys test a quick change battery system in their RC10 Team Car. They setup stick packs with contact tabs instead of plugs and a spring loaded latch. The bottom of the chassis was cut out just smaller than the length of the battery pack and they had a latch on the side of the car that would slide the front battery tray forward to release the pack. They'd pull into the pit, grab the car and pull the lever, the old pack would drop out onto the ground, pick up the car and slide in a new one and off they went. 3 second pit stops. It was pretty cool to watch.

We used a quick release lever from Tamiya (not sure what part number it was). I built a box that the pack (6 cells side-by-side format as used in most of today's cars) slid into with the quick release mechanism at the top. We used Deans plugs that we simply soldered to the packs so we wouldn't have to change the packs from our usual race format. When the car pulled into the pits one of us picked it up with the battery pointing outwards and pulled the body up. Another guy would disconnect the Deans plug, push the quick release mechanism up and pulled the battery out using the plug. Then he would push the new battery in, drop the quick release and fasten the Deans plugs. All in all the Deans plugs cost the most time. If I ever get around to it I want to make a quick release system where no plugs are needed. Just slide it in and CONTACT. Battery changes should be possible in under 2 seconds if you can get it to work. Main problem is to get a good contact that can handle 100Amps plus without overheating and then keeping that contact through a 5 hour race changing batteries up to 30 times...

Back in the day running stock motors in off road I don't think they were pulling any where near the amperage you guys were pulling in a touring car. So the contact tabs were fine.

It is not allowed to use Brushless or Lipo power.

Is that new Orion head allready out?
It would be nice and easy to use those connectors or I could use some Kawada connectors on a classic motor head.

Orion:




Kawada:
This is the solder on tab version;



Or the brush holder version:

Thanks, I know this one but you can't use it on a modern TC with the battery on one side.
