Re: Li-Po setups

[ph2t]

Hey Klims. Here’s some pointers mate.

1) Mini-z’s will work out of the box with lithiums but the steering will be a bit jittery. This is due to the increase voltage driving the steering motor and the eletronics not conditioned to control it at this speed.

2) Polyquest 600mAh lipos fit into a mr-02 with no problems. Hell you don’t even have to remove the battery prongs. Only need to trim the underside of the battery holders so to not damage the lipos. (see my templestowe vid just posted)

3) AAA 300mAh liths are not bad, just don’t run any motors less then 35 turns (approx) with them. This is just to ensure the longevity of the liths. Even at 35 turns you’re still most likely to draw more than the rated current.

4) atomicmods.com has 450mAh lipo cells that should fit fine as well. I say this since the polyquests are bloody rare to come buy.

5) be carefull running turbos on higher voltages. This isn’t a limitation in the turbo so to speak (nelly EVO & Spider 2.x) but a limitation on how the MOSFETS are driven by the ‘Z PCB. you should be OK, just keep above 35 turns as a starting point.

6) traction traction traction! Get foams on the rear dude. Otherwise don’t even bother with an upgrade. (pm me if you want custom foams made to a special offset, otherwise get the gandini’s from the ausmicro shop, bloody great RTR foams, betty and I used them for ages before I spent too much $$ on the tyre truer).

7) Using the AAA li-ions will require the wiring on the battery layout to be changed to make it into a 2s2p arrangement. That makes the setup 7.2V @ 700mAh. Given this, you then can’t (easily) change back to 4 cell nimh if you wanted to.

I’ve listed a lot of points but I’m sure it’s not too hard to go through.

cheers,
