Just peak charged a ZipZap SE, and sure enough, 20+ minutes of run time, included in that was 1.2Km on a Tamiya speed checker, then another 10 mins around the kitchen and dining room.
There is no problem at all with the cells in these cars, just the controller desnt fill them anywhere near enough.
Might be another mod idea.:smiley2:
:)uASee I told you he was a normal person.
:smiley2:uAI last saw surfy on about 2 weeks ago, but I havent seen Mcoupe for a while :question:
:)uAAhhhh, cool.
Like you said LeonLi17, rc slot cars.
What kind of top speed do these things get up to?
:)uA
P.S. I put a friends slot car on the speed checker (with a short piece of track to keep the power on) and it ran at 43kmh.Edited by – micro_Amps on 28 October 2003 10:00:59
Quote:What peak charger are you using for your cars?I have 2 of them, a Pirahna charger, and an SJ Swallow charger.
Both will charge as low as 100mA, (pirahna does 50mA) this is important as you need this low for small cells.
The Pirahna does NiCd and NiMh, the Swallow does NiCd, NiMh, LiPo and Pb.
Stores like Jaycar and Dickies sell peak chargers but check on the minimum charging current, many dont go down to as low as 100mA.
I got the Swallow recently for LiPo cells from a place in Tassie (online) um, ozeflight.com.au here’s a link to the chargers page, they can get pricey but if you buy a good one it will do all your models and anything else that has rechargable cells as well.ZZs dont look too ugly if you lower the body on them. Thats my only gripe on them.

Interesting, no steering though. They seem kind of like larger versions of bit racers being track runners, but with an rc on/off.
I’ve been using a mini 4wd speed checker, and didnt even know about the mini 4wd cars.

A delta peak charger feeds a constant current into a cell, whilst monitoring the voltage accross the cell. As the cell charges the voltage will increase to maintain the constant current input.
As the cell comes up to “full” the voltage will start to drop, at this point the charger switches off, or goes to trickle charge because the cell is full.
“Delta peak” is the ‘rate of change’ (or delta) of the maximum (or peak) voltage that happens when the cell is full.
This kind of charger is usually automatic and fills a cell to 100%, or close to it.
Very handy thing to have if you have rc toys with nicads or Nimhs in them.
A must I would say.
Makes a BCG standard 50mAH cell run 20 minutes.
So there you go, another midnight microamps charging lesson.:)uA
Almost forgot, yes there are several different Zipzap SE models, but you will have to do a net search for them. Probably start at the Radio Shack site I suppose

Something like that, or, I imagine him to be like a ‘gollum’ type of character.
:)uAHi Val,
these can be tricky to set up, the problem is most likely in the fuel delivery somewhere.
If it slows down, sputtering and stops, its too rich. Wind the fuel needle valve in 1/4 of a turn and try again. Repeat until it improves.
OR,
If it revs high and then dies (and probably has trouble re-starting too) its too lean, try turning the needle valve out 1/4 turn and try again.
Also check the end stop on the throttle, it maybe closing off too far, causing the motor to stop.This is just my 2 cents worth, my nitro car days are ancient history, any one with more recent nitro car experience, feel free to add thoughts.
:)uAWhy kill a watch to do this.
Once you open it, you will find exactly the same as what you can buy anyway, tiny bright leds.
No mystery there, just a dead watch.
:)uAYes of course, as always, the controller only puts in tiny bit of power into the cells.
Peak chargers take a bit longer, but do the job properly.

:)uAThe front springs do work well. By the way, the new ZipZaps (1.0 and SE) are now being sold with spring front ends.
I think ph2t had a thread in ‘For Sale’ re the front suspension springs.
:)uAB.K., I’m not sure there is any more to life than the internet and toy cars any way.
What, you mean there is life outside of the house too……nnaaaahhhh.:D
Never
:)uANah, c’mon that would take away all the mystery.
I’m sure ‘admin’ whoever that person might be, much prefers to lurk in dark corners and narrow alleyways, leave him alone, he’s just shy thats all.:smiley2:
:)uAThats true. Lowering is possible, bdebde’s car (my website) has been lowered, which looks great.
Battery run time will be a challenge because there is just no extra room in there. I’m working on a LiPo cell which will give 3.7v and 150mAH, should be faster and run longer, but they are “hassle” cells with charging and all. Wait and see I suppose.
Any other battery ideas would be appreciated.

:)uAYes me too on this one. If anyone has had success finding something suitable please post it here.
The sponge will be the best tyre for these cars (just like the larger cars)but I dont know of anything that will fit….yet.:)uA
I’ll let ph2t answer this one, he is the spring king. If you ask nicely he might even fix you up a deal as well.
:)uAQuote:Is all of this true? proportional steering and throtle control. Front and back lights. Any thing else I am missing? I didn’t pick one up this go but may next time:)Its all true Imprez. Also a choice of 6 channels that can be selected and changed on the cars when they are charging up. One car is capable of any of the 6, it just depends which you select when you charge.
A little dissapointing on speed, but once they are fet modded they fly too.:smiley2:

:)uASurely there is a GMT+/- adjustment that can keep us on track. I havent noticed this time difference in the past when this changed.
:)uAI have used 2 pairs of needle nose pliers.
Or if you turn it over and hold it (like in a small vice), you can tap the pin out from the knuckle side.
Goodluck
