You REALLY should just order one of CJB's 18v upgrade boards, they have a 12 tap to run accessories, but you'll probably have to trace the wiring down to see if you'll have to wire-in relays to handle the 18v to the motors! I've got 4 so far, and the turbo timer's also help to smooth the shock to the gearboxs.

why does everyone waste money and battery life with voltage regulators, when you can just wire a separate 12 volt circuit for your accessories from two of the 3 6 volt batteries?

Two reasons I would use a voltage regulator for this:
(A) You don't get uneven draining of the batteries. if you wire 3x 6V batteries in series and hook lights and relays up to the lower two, they will drain faster than the "top" one which is only used for the motor, and you'll be required to do individual (balance) charging every time, instead of just occasionally.
(B) You can get odd voltages (eg. you want your lights to run at 13.5V so they're brighter). And it will stay consistent even as the batteries drain down
(C) you can change the input-side topology (eg. from 3x6V to a 5S Lithium Ion battery) and it will still work.
The cons: They don't like getting wet (and/or you have to spend more money to get a waterproof one)... And they are money.
I think this is up to the user as to what they need it for, but your point is valid -- for a 3x6v setup there are other options.

Thanks. they are valid points, well said.
I guess as my plan is often to run 12 volt cars and add the 6 volt as a NOS boost on a relay, it doesn't occur to me to get a voltage regulator.
Cheers!

24v Plug and play module that will replace the 12v circuit board in Best Choice cars but will eliminate the RC funtions:
