Not for racing, but for letting beginners get into 12th, I was considering running a airplane 1800 LiPo 7.4v with a Mabuchi - very cheap. Esentially the same set up as a M03 Mini Cooper but in a low CG, light weight, foam wheel car. Not rediculous high speed, but slower and light weight to save tires, cheap batteries, cheap speed contoller, emphasis on running good lines.
Any thoughts?

I think it needed some throttle or esc adjustments because just touching the throttle would cause the car to leap forward, slow corners required careful modulation to negotiate them. You could hit the straight and with less than half throttle go faster than anything else on the track, then half way down punch it and it would spin the tires until the shut off point. It was so much fun i almost peed my pants
7.4v would be a two cell lipo--they run 3.7v each.
My thinking for lipos was that a single cell would probably be close lap time wise to a "normal" 4-cell car, off-setting the reduced voltage with the substantially reduced weight allowing higher corner speeds and quicker acceleration/deceleration. Another field-leveler might be running the two cell lipo with a 55-65 turn lathe motor. Not surprising they're a rocket with a "normal" motor as you're pumping even more voltage into it than we had in the heyday of 6-cell 1/12 way back when...with a way better motor today.
That said, I'm opposed to lipo's in cars. There's WAY too much to go wrong (like burning down your house around them) for the "average" car racer to keep track of.

No need to worry about LiPo's these days. That was a concern maybe 10yrs ago, but today's LiPOs are high-tech purposely made with rc in mind. They are as safe as regular 6 cell, and will never get as hot as 6 cells, dont need to be discaharged, ever, and can be charged time after time. They have much lower resistance and will not catch on fire unless you BBQ them. Everyone is doing LIPO's, and according to ROAR staff, they will be mainstream within 2 yrs and make 6 cell racing a thing of the past. They are only working on reconfiguring the voltage from 7.4v to 7.2v or less.
