I was going s-can, but am now curious...

tbh the only reason i used that motor is because i already had the inline pod printed ( laziness)
the chassis design would take an IL or AW pod
was easier just use that and that Ninco NC6 motor was a spare
it was just a time thing , due to work commitments
actually the weight distribution has worked out well with that motor setup ( so haven't added any )and the whole thing comes in at 89g 'with' the original interior and glazing , so could be a lot lighter
went for 8 x 26 gearing a little bit more brake and grunt hopefully from a lack luster motor ( rally circuits in mind )
haven't had time to try it yet so this weekends B2JG will be its 1st outing as a bit of a side note , but feels smooth and is very quiet when powered

Aren't Rally Slot cars typically inline (in club and event rules) ?
If I made it anglewinder , I'd be up against the moslers Tappingfoot

I was thinking inline s-can. Just to spice things up, I think I will go that way!

edit...or is the long can option to maximise magnetic motor attraction?

This is where you have to go the way you want to go. Thumbup

There is no right answer.

Going long!

Oh crap... why did I have to find this thread *checks ebay*

Not going to fabricate the wheel arches after all.
I just don't have materials or the skills

Yes, the rally rules require in line. However, there are exceptions for some events.
The advantages of the Long Can vs the S Can are that the Long Can has almost twice the torque of the S Can, for the same rpm motor. And, the extra weight helps lower the centre of gravity. The Flat 6 is another option, has a bit more torque than the S, but not as much as a Long. It helps lower the centre of gravity and is shallower, so may be the only option in some cases.

My preference is to go for 21,500 -22,500rpm Long Can motors as these have 300-450gm.cm stall torque, gearing can give you the top end or bottom end performance you want, and, regenerative braking seems a lot better than on higher revving motors. I think this is probably due to the amount of rotational kinetic energy that is present in the higher revving motors at the top of their rpm range.

I've seen a Scaleauto Junior motor, which is 18,000rpm and 300gm.cm. This may be even better for acceleration and braking response, so am tempted to try one. I am just a bit nervous that it may not have the legs for our club track main straight, but should be good on all rally tracks.

I have a spare Scaleauto junior sprinter left over from my DiSCA GT3 builds, so that's the way I am going to go with my motor.
