Title: question about miniz speeds
Post by: Ian on September 25, 2007, 01:49:31 AM
silly question, but how slow can you make a miniz go?
I want to get one for my 3 year old and slow it way down.
Or does anyone have a suggestion..
Then she won't want to drive my 1/12 scale so much

Hi, Ian.

I'd say that your best way to slow it down is to do a couple of things: leave the kit stock motor in and use the included 6 tooth pinion. You can also purchase some inexpensive GP950 (or better) cells which are quite soft but have lots of run time. And last, but certainly not least, turn the throttle end point way down on the radio since you can't do it on the inboard speedo.

Good luck!
Phil

You can also make a fake AAA battery for one of the slots, we did this with our Mini-z's and it slows the car down. Our fake battery was a piece of aluminum stock with one end machined with a bump to resemble a battery.

A current limiting resistor in series with the motor might also be a good idea.

Although this will decrease the top speed somewhat, it will also protect the motor from damage when it is stalled, and will in general decrease the performance of the car, all the while increasing run-time.

Thanks Phil and Dave..
The next logic question is where is the best place to get a RTR kit. Does anyone have one they want to sell..
Batteries are the best from ebay, correct?
Thanks again..

Thanks

After some testing, Barry, Adam and myself, determined that the Energizer AAA NiMH batteries that London Drugs and others carry had a excellent run time. We purchased known brands from Asia and the US such as GP and Sanyo. For us, the Energizer beat the other brands in run time and life span.

I use the Energizer quick charger that can charge both AA and AAA. It charges in about 25 minutes, the batteries get very hot but they seem to like that, Barry used the slow Energizer charger and my batteries had as long run time or longer.

hey Ian, if radioshack has any Xmods left they were down to 15 bucks or something! They work pretty good, not as good as a Mini-Z but depending on the application (playing with kids) they are pretty darn close.
