I like this forum already - you guys are quick! I haven't tried any other batteries for an extended time because I get lazy and don't want to swap the pinions around when I stick the 2s lipo pack in there. I've stuck to the 3s a123 because that is what I want to use long term due to ability to quick charge. If I were just racing at the track with two 7 min qualifiers and a 10 minute main with an hour between each session I'd be ok with 2s lipo. But when I get out to the track I usually run for a couple hours solid and need the 3s a123 ability to quick charge using a standard 12v supply.

I can run the car onroad with top speeds around 40 (not sure if that is with 13t or 16t, forgot what is in there at the moment), but it was clocked by someone with a radar. Onroad the motor will not get nearly as hot as it does at the track.

20/86 is the tallest combo I've got to try I believe. Thats got to be well over 50 mph at 10v. I'll have to set my epa at 70% if I am going to use the full trigger.

Is there a motor heat sink without a fan that is going to fit with the rustler transmission... and actually work to bring the temps down? I like the 16t speed and feel - just don't want to ruin my motor or have to constantly check the temp.

Oh, timing is set to minimum, punch control at 50%, no drag braking.

Thanks - Chad
