Attaching LW20 leg to PRISM Sky

THIS IS A ROUGH DRAFT

Watts Innovations sells a long leg set + external LW20 setup to allow stock PRISM Sky machines to perform deliveries with REEL! Below are the steps to install the LW20 mount and connect it to PRISM Sky

Step 1: Remove the M2 screws highlighted in blue and the Philips head screw highlighted in red. Then remove the front FPV cover by gently pulling on it.

Remove these 3 bolts.

Step 2: Remove the right rubber seal highlighted in green and cut an X pattern in it using a knife. This will allow it to still be relatively water tight however it will let a cable pass through it. Replace it back in its original location marked in orange.

Cut an X in the rubber gromment and re-install it.

Step 3: Run the LW20 cable through the hole on the rubber grommet and then plug it into I2C on the front auxiliary board marked in red. This port is located right beneath where the FPV camera is plugged into.

Plug the LW20 cable into the I2C port.

Step 4: Reinstall the FPV Camera housing and tigthen the M2 bolts to a torque of 5.7in-lbs. Carefully tighten the philips head screw until it is snug and tight.

Step 5: Organize the LW20 cables on the payload rails as shown below. You can use velcro or electrical tape to secure the wires to the rails. This step is very important, if done improperly the cables can get cut by the propellers or become unplugged in flight!

Step 6: Slide the LW20 itself down on the leg until it is well out of the way of any box that could be attached to it. We advise to twist the LW20 around the leg to take up the wire slack. The LW20 should be about 7.5" away from the ground to allow for optimal clearance from any payloads attached to REEL. Make sure the M3 bolts for the LW20 mount are properly tighten so that it can not move on the leg itself.
