Airtronics will work great. They are one of the best servos on the market. Alot of guys use KO which is pretty similar to the JR.

Stay away from the Hitec line and the cheaper servos...

the airtronics servos are great, but I have had the same two hitec 925's since 1999 and they still work flawless. not too impressed with the lower line hitecs but the 925 and 945 are very reliable.

Cool Little help please...........

I've been raceing (around the yards and feilds) Nitro 1/8th scale buggy for a few years, But I had to pick up the T-4, and I love it. I am not very up to date with all the ins and outs of battery care. Is there a fast, ( and SAFE ) way of cooling them down for the next charge, after a hard run. I've got Orion 3300 matched packs
Thanks for your time

I'm not an expert, but every book, and web page I have been to says no more than 4.0 volts, and just till the pack gets warm, unless you have a peak charger that takes care of that.
Some one will have more info I'm sure.

Default Charging

You probobly ment 4amps. Your power supply (even if it's a car battery) puts at at LEAST 12 volts. If you have matched packs, they say what the charge rate for the batteries were when they were matched. I'd go w/what the label says. Otherwise, 5A is a pretty safe number. Your right about the temperature. Keep an eye on that. One thing to keep in mind..generally, higher amp charge = more punch, lower amp charge = more run time. HOpe this helps.

You could check-out www.promatchracing.com. They have some charging tips there.

HeY!!!


When it's all done charging and you pull the pack off it shouldn't be no hotter then about 125 degrees. Most 3300 packs they recommend to charge at 6.0 amps.

Sounds like I have been charging my packs at too low of amperage. When its done they are barely warm. They are a matched set 0f 3300's and you say that it will say on them what they were matched at......I will try that and or adjust to 6amp because I dont have the punch and thats what i'm looking for. I am not getting over the double jumps like everyone else! Good some thing to try for Friday night. I have too much juice left after a run so that should have told me something!

Most labels have a section w/ "CHG" then 5.0A or whatever value.

browndawg and others, you need to know the peak detection of your charger in order to be safe. that is the amount of fall the charger allows after the pack is charged before shut off. older nicad chargers allowed around 0.10 fall in volts before they quit. the newer nimh cells will vent or explode with this much over charging. in order to be safe your charger should stop with around 0.04 to 0.06 volt decline. that is why with an older charger you must charge your packs at such a low amperage so they don't overheat your cells to quickly. most good chargers allow you to set the peak detection for each charge application. the millenium/pro, lrp pulsars, reedy quasars,ce turbos all have this function. if you get one of these then you can charge at 5 or 6 amps no problem.
