haha we all talk about temps and temps and temps but honestly after two years of racing 1/8th electrics and building/setting up over 14 1/8th scale cars the BIGGEST varition ive seen in temps is just handing the remote to someone different....

GREAT example, i setup a Losi8 the other weekend with a MMM, $40 ezrun 2350kv motor, and 4s 5350 pack geared for over 40mph, and the ezrun motors have those HUGE fans on it, i let the guy drive it around for 10 minutes and he never broke 120 on that cheap motor or 100 on the speedo and it was 95 degrees out side, he gave me the remote for 2 mins i had the temps up to 165 on the motor, 145 on the esc, and 125 on the lipo...... in 2 mins! i gave the remote back to him and he ran 5 more mins before it started to slow and when he pulled it off the temps were back down at 125 motor, under 100 esc, and right at 100 lipo......

i personally run 5s in my truggy and after a 6 mins race im at 160-170 on the 1515 2.5d motor and 140 on the mmm and 110 on my rcm lipo, so if a setup works for you doesnt mean itll work for someone else, i drive the hell out of my truck every time it touches the track, i have the track record at 3 tracks in the state with it and run those kinda times every race, but when i hand my radio off to others they could run it for over 20mins and temps would be low, with me driving i cant run more than 10 at my race pace....i can also tell a HUGE difference in runtimes my gf drivng my truck can run it for over 25mins on the track while i can dump the pack in under 14 now....

what im getting at is yea you could make a 3s setup work, but if your buying a system... go low kv and high voltage their are no down falls. if you already had a mmm and 2650 motor laying around im sure you could run that in a truggy fine on a PAIR of 3s in paralell with fairly low gearing.... but dont purchase a system with the intention of running 3s...
