Povd next time you hear someone complaining about how banggood scammed them out of thier hard earned money just remember there's people many more people just like this guy out there.

Povd I had the same issue when I received my l8s. to fix this issue you need to turn the power up to 100% in the p settings using the screen by the throttle

Povd you most likely ordered option 2 witch doesn't come with any electronics, just the the truck frame and body. option 1 comes with the electronics but it's more expensive, maybe you can contact banggood customer service and tell them you made a mistake ordering and see if they will let you purchase the electronics for the difference in price from option 2 and option 1. not sure if they will do it but its worth a try if you want to spend the extra money for them

Povd MG chemicals makes a much better product for waterproofing electronics then liquid electrical tape, its called silicone modified conformal coating and its specifically made to waterproof electrical components. its more expensive then liquid electrical tape at around $15 for 55ml but it takes alot less product to cover the components, the layering is thin enough that you could waterproof under heatsinks and it won't lower the affectiveness, it glowa under uv light so you can check to be sure you have your components are have been fully coated too.

Povd I had the same issue on my artillery sidewinder x1 then I noticed the ends top was a bit out of line so I moved it back and tightened it up and the issue was resolved

Povd Rixxxxx has it correct, the switch on the esc it to turn brake on or off according to the product description on this item.
