User questions & answers

Question:	How much power can each of the four motors in the diy kit produce
Answer:	Not much as they are small cheap 6V, common DC motors. Moreover, they are not throwing the same output although feeding them with the same input.
Question:	How to connect the wires with 4 motors
Answer:	Our product videos have tutorials.
Question:	The chasis is made of what
Answer:	The chasis is made of plastic, we use the box packaging, do not worry about being crushed
Question:	Can you replace the 4aa battery holder with a 6v solar panel? and is there a maximum voltage/amp rate, e.g 9v, 10v, or 12v? thank you
Answer:	Solar cells also need a charge controller. currently to large to be installed unless you build a scaled 48/53 foot semi trailer to mount it in} The controller provides a study, consistent voltage/wattage to your batteries. Cause you can not do so from the sun. Clouds, time of day, panel angle extra will alert your output. But the controller maintains your batteries with a consistent enough charge as to not damage them. See some solar charging units, also be sure if using lithium batteries you get a compatible controller.
