How to assemble
The frame structure is assembled from paired carbon plates which are bolted together using standoffs between the plates and bolts from each side into the standoffs. The parts key together at the edges and thus lock together.
Assemble lower frame and legs
- Assemble one leg using an inner and an outer leg piece, nine 20mm standoffs and 18 N3 bolts.
- Assemble a second leg per step 1 using remaining inner and outer leg pieces. Be sure to assemble it as a mirror to the first so a left and a right leg are created.
Assemble arms and motors
Assemble gooseneck bars
Instructions for assembling the kit can be found here.
One possible layout for motor rotation:
OpenPPG can be folded up for easier transport. To make it flight ready:
- Lock arms and baseplate with hinges
- Attached hoop pieces with plastic spacers to arms
- Secure netting (?)
Suggested batteries: https://openppg.com/shop/batteries/bonka-22000mah-6s-lipo-battery/
OpenPPG requires 48 volts. Batteries must be installed in series to obtain 48 volts. Additional batteries must be installed in parallel.
Batteries may be attached to frame using a large strap: [PIC NEEDED]
Or with a DIY box: [PIC NEEDED]
How to charge:
Always inspect your batteries for dents, tears, or other damage before each use.
What is balance charging?
What NOT to do when charging:
- Do NOT overcharge! This may cause fire.
- Do NOT leave your batteries charging unsupervised.
- Propeller arms locked open
- Cage and netting secure
- Batteries securely attached to frame
- Battery connections in correct setup (parallel & series) and connections secure and away from props
- Harness secure and no loose straps
- Turn on power switch
To arm the motors for flight:
Double click the flashing button on the top of the controller. You will then hear a tone confirming the system is armed.
To disarm/turn off:
Double click the solid red button. You will then hear a tone confirming the system is disarmed.
When flying with only 2 bonka batteries, batteries may overheat. It is suggested to fly with a minimum of 4 bonka batteries (or equivalent).
When flying with 2 batteries it drains a lot of current from the two packs. Flying with 4 batteries will drain 2 times less current (amps) from each pack, resulting in less heat generated at the battery pack level and the connections.
