cad- just get some small fuel tubing and mini zip ties... but even doing that it'll look sorta big

for a car cleaner use a mixture at a rate of 1:1 of denatured alcohol and water and if you have a metal chassis spray WD-40 on it and wipe off the excess. This coats the chassis in a thin film of oil and will prevent dirt buildup helping to speed up clean up time. The chassis won't feel very oily but rather how it feels when new from the box.

Also if you keep bending body clips due to flips just use some 22 or 24 awg wire and twist the ends together.

To thread the antenna through the tube faster and easier just wet your fingers and run them the length of the atenna and thread away!

On maxx trucks with plastic shock towers, if they break just zip tie the top part and bottom part together very tightly to keep driving, also you might just want to do this even if your tower isn't yet broken as it reinforces the tower, also good for when you're racing a maxx truck (yeah right )
