Questions on heat

You can only descide for yourself what the ideal gearing is.

If i was put in your place, i would just try it and ask a person who had a lathe, to drill out a 3.2 bore to 5mm on different pinions. (or you could order a few from Mike) Just measure the temps on the speedo, motor and batteries.

Just measure the temps, that is a very important value. Also look at the temp on your batteries, because their lifetime will be shortened when constantly pushed to their max.

Do you think you need both gears (1st and 2nd?) i personally really fancy the G-maxx 1 speed conversion. It would shave of a little weight as well (shiftingservo, gears, one piece of the gearbox)

4.5kg RTR is very light! (9.9 lbs, for the non european.. ;) )
