Stupid Question: BEC sequential gears
Stupid Question for you:
How does the sequential shift on a BEC car work? I understand that it's not a case of...
N <Pull back> 1st <Pull back> 2nd ...
but does it go...
N <Push Fwd> 1st <Pull back> 2nd ...
or
N <Push Fwd> 1st <Pull back> N <Pull back> 2nd...
I hope that makes sense?

Why no longer considering a Mac 1, great kits?

Depends on how you make the linkage.
Push into first then pull back thereafter is a common setup.
I have also seen the opposite setup - which makes no sense to me.

Whichever way you set the levers up, N - 1st will be in the opposite direction to all other up-shifts.
You go through N to get from 1st to 2nd but it literally does go straight through.
Therefore 1st - N is acheived with a gentler push/pull and
1st - 2nd is acheived with a stronger push/pull.
Does that make sense?

Neutral is half-way between 1st and 2nd.

the gears go 1st-N-2nd-3rd-4th-5th-6th. 1st to 2nd or 2nd to 1st is a “double clunck” with neutral in the middle if you don’t push the lever as
far.
Most setups have forwards going down through the gears and backward up, though some are the other way round.

It's as close as I've seen to what I'm building (looks wise)

I guess the reason its arranged like this is so you can never "go off the end" of the gearbox and select neutral when you're
changing down, as you'll only ever get as low as first and as long as you shift properly, won't find neutral inbetween.
If you had neutral below first, then when shifting down you'd need to count the gears to ensure you got to first and didnt accidentally go one
further and drop into neutral, which could be dangerous as it leaves you with no engine braking, especially on a bike.

That, and so you can shift into neutral from second when aproaching traffic lights etc. It stops you having to go through first.

I prefer having down shift going forwards. Then under braking (when you'll be down shifting anyway), you're naturally pushing the stick
forwards..... On acceleration you're being pulled backwards as is the stick....
Makes more sense to me

So which way have people got thier paddle shifts. Mines up change on the right pull and down change on the left pull.

Mine's tuther way, which as another BEC owner said seemed correct to him. He has an S2 Lotus 7 with a 'Blade with the gearstick in the
conventional position, which meant with my paddle shift he'd just use his left hand, pulling back to go up and pushing forward to go down.
Not that I'm saying that this is correct - it was just the easiest option when I was making my linkage!
