OPENPPG: AN OPEN-SOURCE ELECTRIC PARAMOTOR

An electric paramotor you wear like a backpack and take to the sky — near-silent flight, a battery pack, and open CAD. Serious flying gear.

COMPAREE VERDICT

OpenPPG is genuinely wild: an electric paramotor you strap on like a backpack and fly with — quieter than a two-stroke, batteries instead of fuel, and published CAD. The team has even posted a long uncut flight it calls a world-record electric flight-time attempt. We're flagging this hard, though, because it's not a maker novelty — it's aviation. You're leaving the ground under a large spinning propeller carried on your back, powered by a high-voltage pack. That demands proper paramotor training, not a weekend of tinkering. On top of that, this repo is CAD only — the frame, power-pack and hand-controller files — while the controller firmware sits in other OpenPPG repositories and openppg.com sells the finished paramotor; there is no published BOM or build guide. Admire the engineering; pursue it only within proper flight training and safety.

GOOD TO KNOW

  • —This repo is CAD only — STEP models of the SP140 frame, the electric and petrol power packs, plus STL/3MF files for the hand controller case and net rods
  • —No BOM or step-by-step build guide in this repo. The controller firmware is in other repositories of the OpenPPG GitHub organisation; openppg.com sells complete SP140 paramotors rather than DIY kits.
  • —No license file in this repo
  • —This is real aviation gear: flight plus a large spinning propeller — trained certification required

BUILDS OF THE WEEK

Five open-source builds worth your weekend, every week.

Checked like this one: what’s really in the repo, what it costs, how hard it is. One email, unsubscribe anytime.

Can I build this?

Printreference the CAD (STEP) for the frame and power pack
BuyIn practice a complete SP140 from openppg.com plus a paramotor wing; the CAD here is a reference, not a parts list
Toolsaviation-grade assembly, electrical work, and proper training
Skillsexpert: paramotor/paragliding certification plus high-voltage electric
Timea serious project — plus flight training
Costband $$$ — motor, ESC and a large battery pack; current prices: openppg.com
SafetyHIGH: flight, a large spinning propeller worn on your back, and a high-voltage battery — trained certification required, not a casual build

Build at your own risk. Projects involve tools, electronics and sometimes mains voltage — follow the creator’s safety notes.

Start here

Navigation into the creator’s own docs — we don’t rewrite the guide, we route you to the source.

  1. 1.Understand it's aviation first (training and certification before anything)
  2. 2.Watch a flight test (launch, cruise, glide)
  3. 3.Review the CAD (frame + power pack (STEP))
  4. 4.Get parts and full docs (openppg.com sells complete SP140 paramotors; the firmware is in the OpenPPG GitHub organisation)

KNOWN ISSUES

  • This repo is CAD only (mostly STEP). The firmware lives in other OpenPPG repositories and the SP140 owner's manual covers assembling a purchased unit, but there is no published BOM or DIY build guide.
  • No license file in this repo — check before reusing the CAD
  • It's aviation: flight plus a large spinning propeller on your back and a high-voltage pack — trained paramotor certification is required, not optional

You really wear it and fly?

Yes — a paramotor is a backpack propulsion unit flown under a paraglider wing. OpenPPG makes an electric one: near-silent, battery-powered, with open CAD.

Why the heavy safety flag?

Because it's genuine aviation. You leave the ground under a large spinning propeller worn on your back, powered by a high-voltage battery. It requires paramotor/paragliding training and certification.

Is the whole thing in this repo?

No — this repo is the frame, power-pack and hand-controller CAD (mostly STEP, with some STL/3MF print files). The controller firmware is in other OpenPPG GitHub repositories, and openppg.com sells complete SP140 paramotors; there is no published full BOM.

What does it cost?

Band $$$ — the motor, ESC and a large battery pack are the main costs. openppg.com has current prices.

FROM THE COMPAREE TEAM

Electric paramotors trade engine roar for near-silence but carry battery limits on flight time. For something strapped to your back in the sky, which propulsion would you rather trust?

Correction (4 October 2026): we re-checked this page line by line against the project's own repository, documentation and videos, and fixed errors in earlier versions.

OpenPPG

OpenPPG builds the SP140 electric paramotor and publishes its frame and power-pack CAD and its controller firmware; the team has also posted a full uncut flight with a modified SP140 that it presents as a world-record electric paramotor flight time.
