I don't own a Epoch yet but I was surfing around this part of tiny r/c .I do know slot cars that were my name slotsurfer came from.
I would not use the motor on the right it is a cheap tyco can motor used in the HP7 slotcar.Their is a company called scaleauto that make high performance can motor the same as the can motor in the epoch I have used this one personally
145 - SRT / Turbo "High Power©" Can Motor cost $10.00 very fast motor and I think the epoch could handle this one. The least amount of voltage I have run this motor at was about 8 VDC.The stock Epoch I have run at 6 VDC I own a MG variable power supply.Now Gary Beedle who own Scale auto is one of the finest armature builder around he make 4 really hot can motors
BSRT "Spud Power©" Can Motors Cost $28.00 each I really dont think the epoch could handle this because we usally ran this type of arm at about 22 VDC 10 amps per lane.We still would burn the motors up if you ran your car to long. You can buy the standard motor for $4.00
Model #8807 Have fun don't smoke your motor
