SS + ZZMT = SZMT, My SuperZip MT

I've always had a soft spot for the ZZMT. I've made a few quad cells but could never harness the speed very well. I decided that extending the chasis a bit would probably give it more leverage.

Before this project I had a quad cell with a 10 tooth pinion and orange motor and gears. This had a gear ration of 11.78:1.

I tested a ZZMT orange motor with 4V stalled and it drew around 1.4 amps. My quad cell with 5V then would probably draw around 1.6-1.7amps.

I had an idea to use a pair of SS motors for more power. I opted for the orange 22k. At 4V stalled, these draw just about 1 amp. I decided that I shouldn't go over 3 cells with a pair of these for fear of frying some FETs, which is still a risk at this level.
