OpenPPG X4 Kit [V4]

OpenPPG X4 22 was an experimental paramotor platform. It featured a fast-folding frame that allowed for easy transportation, a truly zero-torque four motor design, and was the lightest paramotor on the market-

Discontinued

Note: Due to the high demand for the SP140 here, we are discontinuing the X4 system, so all effort and resources can go to the development of the SP140 system. The X4 had a smaller percentage of sales, and the SP140 was best for 95% of pilots, so it’s best that we consolidate our resources and focus on making the SP140 the best it can be.

The OpenPPG X4 22 was a revolutionary step forward in the sport of paramotoring. It featured a fast-folding frame for easy transportation, a truly zero motor torque design, and weighed only 21 lbs—making it one of the lightest paramotors on the market. Despite its many advantages, the OpenPPG X4 22 remained remarkably affordable, costing nearly half the price of other top-tier PPGs.

However, its flight time was limited due to the inherent inefficiency of the four-motor design, which made it better suited for short, low-altitude flights. Many of the insights and lessons learned from developing the X4 directly inspired the creation of the SP140—our best-selling single-motor electric paramotor. The SP140 offers greater efficiency, longer flight times, and improved performance to meet a broader range of pilot needs.

Features

Foldable – Quickly folds up into a compact size and easily fits into a small car’s seat or trunk.
Light Weight – The whole electric paramotor weighs in at only 21 lbs, it’s by far the lightest gas or electric paramotor on the market.
Maintenance free – While other internal combustion Paramotors require costly maintenance and rebuilds every so many hours, electric paramotors don’t.
Reliable – Fewer moving parts required to fly this EPPG makes it far more reliable, and does not need the constant tweaking gasoline engines require.
Zero Torque – OpenPPG 22 is truly a zero-torque paramotor. Two of its four motors spin clockwise, and the other two spin counterclockwise, which cancels out any torque effects.
Affordable – Costing nearly half of the closest PPG or EPPG on the market while being packed full of features it’s by far the most cost-effective paramotor right off the bat. Not to mention the thousands of dollars in maintenance cost that are saved.
Fast responsive throttle – Electric motors allow super responsive, precise control of the throttle and allows very linear throttle response which is not possible with two-stroke combustion motors.
Easy to start – Just push a button and you are ready to fly. No pull-starting struggle required, which is incredibly convenient when it’s on your back. Also when launching your wing the propellers don’t have to be spinning so it eliminates the chances of propeller tangling your lines.

Recent Improvements

Latest updates: Added full ESC amperage measurement for precise battery life estimation, designed for higher voltage 7S batteries

Redesigned Frame PCB (Hub)

ESC Telemetry Support — Captures RPM, voltage, amperage, internal temperatures for each ESC/motor
Barometer for altitude estimation
Ambient temperature sensor
Blackbox logging to MicroSD card
IMU for 3D position sensing
Two-way communication with hub
Electronics over voltage and reverse polarity protection

Controller

Improved top LED button
Easy updates from any computer without software or driver downloads
Adjustable elastic hand strap

Unlike a traditional two-stroke there is no engine to idle — throttling-off produces silence… That’s so cool.

X4 Kit- Included all necessary parts to build and fly except harness, batteries, and wing. Some basic soldering skills are required but the frame is easily snapped and bolted together with Allen wrenches. Netting is pre-stretched, riveted and installed on the tubing/frame. If you don't mind assembly and basic soldering the X4 kit will take about 6 hours to build. Batteries will need to be sourced by you, we do have recommended battery's on our site but they need to be ordered separately as they ship separately

SP140 - Requires no assembly or soldering, just plug in your batteries that are included in the box and you are ready to fly. If you don't like the DIY aspect and you just want to fly this is the option for you. We recommend the SP140 for 95% of pilots as it is simpler to operate and has close to twice the flight time of the X4.
