Nobody has given him an exact response for what to buy, so...

I have ordered from these links before, both work as expected.

18 AWG wire (Black and red): http://www.ebay.com....BMAAOSw-7RVFTk4

18AWG is all you need. The resistance wont worry you anyway, no point wasting that extra money and space inside your blaster.

Microswitch: http://www.ebay.com....m//321705842639

The microswitch is rated high enough for the job. Ive used higher rated switches before, no noticeable difference between them.

EDIT: Somebody has given him links, but from manufacturers websites. These links have free shipping aswell.

 I would guesstimate that the startup draw from those motors (MTB RHINOS) at 14-15 volts will be about 12-15 amps, at least. Someone can correct me if I'm wrong.

A bit late of a response, but heres a spec sheet (again) for more precise specification

Yes, in theory, it makes little sense that a 6 cell nickel chemistry battery pack would work just fine with a stock Rapidstrike, but a 2S LiPo pack will not. However, I have only used the former in multliple Rapidstrikes with no problem, but have never tried the latter myself. I have been corrected that a 2S LiPo will not work in  stock diddlerrike. Again, I am skeptical, but I wanted to inform the OP of what I had heard. Perhaps there are loose tolerances with Rapidstrike wiring and electronics.

Yeah sorry, forgot about the higher amperage, etc. and stress on the low quality wiring, a lipo at 7.4v, depending on its output, would most definitely not work.

Rugerroo,

 

Are you saying that if the OP runs a 10 cell NiMH with MTB Rhino motors he will get the same motor life as if he ran an 8 cell NiMH pack? And whether he does or doesn't, is it your position that running MTB Rhinos with a 10 cell NiMH pack will give better performance than with an 8 cell NiMH pack?

No,

What I am saying is depending on your use, using a lower voltage isn't necessary (most cases). It would be common sense (I hope) that using slower motors isnt better, that is, unless you want superior lifetime. Im sure running rhinos on 10 cell wouldnt break them so suddenly and last long enough for the average user.

A 10 cell NiMH battery pack hot off the charger will probably be around 14-15 volts, which is probably a few volts higher than a 3 S LiPo hot off the charger.

Partly true, but as stated here, Cells HOT (and I mean burning hot) off the charger will be at max 1.49v, meaning that your cell (unless charged with a specialised charger) will charge up to around 1.3v before the charger turns off (All of my chargers do this, some old ones might not cut off power?). But MTB Rhinos should be able to take the 13-15 volts because they have a nominal voltage of 12v.

Spoiler

The nominal voltage is 12Volts so it would be able to handle 13v-15v easily because, in theory, a nominal voltage is a safe to handle voltage for each motor. The motor life will decrease slightly if it happens a few times (over charged) but could impact the lifespan of the motors terribly.

Also for futher reference for commonly used Motors from this hobby, the 'database' most people refer to is here: https://docs.google....AwW7vg/htmlview
