Yes, I have the single fastest CO27 in existence.









Come on guys, seriously.

I got my first APS charger to try it out. Now I have 2. If you get at the right time, you can get them for 100 bucks or less on rctech or ebay

I think something's wrong with my APS..

I plugged in a 2400 pack to charge, came back 15 mins later and it was displaying "Low Voltage". I have a 20A PS, so it couldn't have been that..

I shut it down, tried charging again, and it said "Check connection".. opened'er up, the 20A fuse blew.. strange..

I replaced it, and tried a motor test. As soon as it give it a bit of voltage, the power supply light starts dimming, I hear a low squeal coming from the APS I think, and it stops, saying low voltage. I haven't tried another battery pack yet, but I can imagine it just might blow a fuse again. The 15A fuse looks fine.

I have a second APS, hooked it up and it works fine with the motor run, so it can't be my power supply.

Time to send it in for repairs?

Got a question about the APS, just purchased it and was wondering what I should be setting my peak mv at for my IB4200 matched cells...Also what should I set it at for my spec battery packs (1600mah nicds) thanks in advance Jeff

can any give me an email address or web site address for aps or its maker

i was charging a battery the other day and my APS shat itself
the battery was an 4200 ib and i was charging at 6amps with a 25mv cut off using a 13v 15 amp powersupply
when it fininshed charging i couldnt change the preference to any thing and when i turned the bloody thing off and then back on the screen just had a line of white squares on the top line
i replaced the fuses to no avail

if any one can help it would be much apprieciated

Hi All,
Just wondering how to analyse the “dyno” results.
I put some well used motor on the dyno last night and here are my results:

Epic X
Max rpm @ 7v 6.5 amps 34000
Max amp @ 6.8v 7.06 amps 33000
CO27
Max rpm @ 7v 7.75 amps 32000
Max amp @ 5.56v 10.83 30000

When I start tuning what is the best to look for, do you just want to see increases in both amps and rpm? How do you read the Max amp figures, is max amp at lower voltage a good thing?

Thanks

Wayne

Hey Guys,

I know it's been over 2 years since this charger has been discussed but I have some questions on this charger. I race mini-z so I will only charge AAA batt. at .8 to 1.4 amps and test 130 motor on it. I have read all 18 pages and still have some questions.
1. I have a 10 amp power supply, will it work?(please remember I'm only charging at the most 1.4 amps.)
2. Will the RPM sensor fit onto a 130 motor?
3. Will a 130 motor fit into the motor stand?

I like to buy this charge because you can charge, test motor, and it is small in size. I have used my friends Much More Motor Master and I like it but it doesn't charge batt.

Thank you for your help.

i have this charger one of the best it think. I wish they had a lipo upgrade.
your power supply will work fine but you will not be able to use the rpm sensor. it is ment for a 540.

you can spin the motors up to break them in but that is it

I would keep mine in a heart beat if then would make a lipo update.

We Need to e-mail them everday to get the lipo upgrade. If they would but in in there their new charger i might buy one more.
