Jomurema is an Austrian company that had a line of upgrades for mini-z as well. It comes with a 1S battery,

The Atomic and GL cars are basically miniature touring cars. Although GL just released a ball link 2wd chassis, which in my opinion is more carpet oriented than rcp oriented. These are all Lipo only designs, based on 2S and brushless. Like anything 2S in this scale, they have more power than really needed for good close racing.

EMU, don't forget about the PN king pins with the delrin ends to reduce unsprung weight.

It would be overkill even on a medium size track as well. This is the dilemma the scale is at right now. Many to guns pushing 2S at the competitive level, which are simply not usable on anything but regional sized layouts or larger with high flow.

I want to do some testing with 1S and see if its worth anything... but need a track for testing, which I currently don't have near me.

Emu you could try a 3000kv with 2s on smaller track. I have not done it but it might work out.

I get a lot of questions from non racers about how fast my little car can go. They really don't understand that faster cars doesn't mean better racing. We get some of the closest and most fun racing from Tamiya mini with silver can motors.

We run our mini z with they kyosho blue eco motor on a large rcp track an the racing is pretty darn good.

Advantage is that the knuckle no longer slides I the kingpin, reduces wear and binding of the knuckle as suspension loads. It also reduces slop especially due to wear.

The disadvantage is increased unsprung weight, and altered spring rate to the wheel. There is also less ability to dampen the front end.

The reversed kingpin overall is a large improvement, especially in box stock class where the stock spring is a little heavier than wanted.

The majority of my mr03 use stock reverse kingpin setups with reflex upper towers to adjust camber with stock knuckles. Cheap and effective.
