I always charge outdoor, yesterday a friend of mine charged his pack (same than mine) in home, only 20mV and the charging finished with the pack at 140F

If i'm running 19 turn I charge at 6 amps. 5 amps if I'm running modified. Like I said. It depends on the conditions where I set the delta peak. Anywhere in the range of 45 to 55. The colder it is or the more wind there is, the higher I go. Even if it's warm, if it's windy out, the breese can cool things down. Indoors, 50 should be about right I'd guess.

HEre we switched to 19T because some drivers are still runnign nicd packs.....the we decided to run only 19T to keep a reasonable race level......

I went to the track today to test my packs, but my speed had problems and I don't know how long can I run with these packs, anyway, it's much moooooooooore than 5 minutes, obviously I can charge at 6 amps....

i'll try 40~50mV next race.....

thanks for helpin Jon.....

I went to the tri-state 200 and finished 3rd this weekend for nitro sedan. I took 3rd in the first main, after an early flameout, and took home the win in the second main by 4 laps. It was a total laps and time event, so the flameout cost me the overall win.

I ran a club race at Hobbytown Newark, 19T. Had some problems in qualifying (still trying to figure out how to make the reedy quad mag go fast and last for 5 min). Ended up qualifying 3rd overall. In the main first and second both crashed in separate mistakes in the first lap, so I was out in front and ahead of the carnage and was able to cruise to the win.

Next week is the REVO race, a yearly memorial race for a local racer/announcer who passed away a few years ago. I'll be running 19T and mini. It should be a great race.

James - I tried the "polarity brush" trick mentioned by Barry Baker and it really woke my Reedy Quad Mag up.

So far i've tried running 767's both full face and with a cavity. They both make good power (i'm running 36* of timing), but i'm just having trouble getting the brushes to last for a run without burning up and making the motor lose a signifigant amount of power. I haven't been running a fan but i'm going to try the associated heatsink fan this weekend.

Thanks for the suggestions about the polarized brush trick, i'll have to try that.

Try the 766's (quasars) when running 36 deg timing in the 19T's. I did alot of testing over the winter and they seemed to be the best overall brush when your running alot of timing in the 19T's.

I liked the 767's in the chameleons, seemed to give the motor alittle more torque.
