3D printed parts, 2ea nails diameter 2mm, servo and associated link/rods etc, tie wraps and double tape, metal ring, long lane, 1 free channel on the receiver/radio
Step 1: Step1: Printing 3D
Base Plate volume: 21986.54 cube millimeter
Hook part1 volume: 2557.12 cube millimeter
Hook part2 volume: 3461.60 cube millimeter
The pictures do not show the servo arm and servo rod.
You don't own a 3D printer? No problem: go to http://www.3dhubs.com/ , register and select a 3D printer in your neighborhood. Pay online and grab it later. Works fantastic.
Step 2: Step2: Surface Treat Your Parts
Step 3: Step3: Assembly and Installation
Now you have two configuration options: place the base plate so the hook is right under the rotor shaft or turn it around by 180 degrees like shown on the pictures. The base plate is attached to the heli frame with double tape as well and secured with tie wraps.
The long lane needs to be at least 1.5meters long.
Step 4: Step4: Testing and Lift-off
PRECAUTION: Be aware an oscillating, heavy load on a short lane can have a severe impact on the stability of your heli. Perform your first flight with an empty tin or light weight object. Depending on your installation configuration: Keep in mind the center of gravity CG of the heli itself and the potential eccentric force from the cargo hook.
BEST PRACTICE: Do not hover too long on the spot. Take off and fly forward slowly but constantly. This can avoid oscillation of the load. Like controlling a crane, placing a cargo needs some practice. Enjoy!
Step 5: UPDATE
Note: two parts need to be glued together with acetone. The upper part (grey) will be screwed together. The two cylindrical parts should be printed in the same orientation to match best! The curved hook part should be printed horizontally.
