JS-2 Analog Build Guide

Note: the Bolt sizes used on the frame and in particular the 6 bolts that lock in the roll cage in conjunction with the standoffs. At either end you use 6mm bolts and in the mid section you use 8mm bolts which allows for the TPU VTX antenna mount.

When installing the TPU VTX antenna mount, the 8mm only need to be just nipped up. Do not over tighten them as they TPU will make sure they don’t come loose.

Note: ESC is secured using 4 Nylon M3 Nuts.
