ADVANCE have been involved with paramotoring since 1990. Back then we took to the air with a powered Alpha 1; in the intervening years our test pilots have spent many flying hours checking out the suitability of ADVANCE models for powered flight. ADVANCE is convinced that because of its user-friendly characteristics a good mountain glider also satisfies the demands of a good motor glider.
Therefore we offer the following models with convertible risers:
ALPHA 4 – Paramotor
The coordinated takeoff behaviour of the ALPHA 4 becomes evident from the wing’s easy pull-up in light wind, the little brake needed to stabilise it and no tendency to overshoot. The damped profile and compact shape of the glider make it particularly stable in the air and provide a high degree of passive safety for both the beginner and the leisure pilot – with or without the engine.
The ALPHA 4 has a DHV1 and EN certification. When fitted with paramotor risers sizes 25, 28, and 31 are certified for paramotoring by the German Ultralight Association DULV.
Convertible risers for the ALPHA 4
The optional motor risers for the ALPHA 4 are convertible, so they can be used for free flying as well. These risers have two hangpoints, about 10 cms apart. The higher ones are set up for motorised flight. (see picture)
The trimmers make it possible to get the best takeoff behaviour in light wind as well as compensate for the turning effect of the propeller. Cruising speed can also be trimmed out at any time. For free flight the trimmers can be led through the carabiners and secured out of the way.
The ALPHA 4 motor risers also have a traditional speed system, which provides for a useful speed 
increase. (see picture – Risers)
DULV-Certification
When fitted with the motor risers the DULV has certified the ALPHA 4 for unaccelerated flight in sizes 25, 28 and 31. The permitted weight ranges are shown below. The DULV standard requires a compatibility test for each model size. The DHV certificate and EN approval for the ALPHA 4 are also valid for free flight with motor risers provided that the lower hang points are used and the trimmers are stowed.
Permitted weight ranges
| DULV | DHV | |
| ALPHA 4/25 | 85 – 130 kg | 65 – 88 kg |
| ALPHA 4/28 | 100 – 149 kg | 78 – 106 kg |
| ALPHA 4/31 | 110 – 149 kg | 96 – 130 kg |
* Takeoff weight (pilot, glider, equipment and motor)
Motor compatibility
The necessary test flights were carried out with a standard engine. Other motors can be used after the manufacturer or the DULV have carried out a compatibility and handling test.
Tests are running with the following engines:
- PAP ROS 125
- Walkerjet XC W130
- Fresh Breeze Simonini
EPSILON 6 Paramotor
Because of its good takeoff qualities, high stability and perfect steering behaviour the EPSILON 6 is ideally suitable for paramotoring. The DULV/EN/LTF certified Hybrid-Risers, which can also be used for flight without the motor, are recommended.
Hybrid-Risers
The Hybrid-Risers are fitted with two different hang points, so that the best match of harness and motor system can be achieved without having to change the brake line length. With the trimmers the turning effect of the motor can be counteracted, and the airspeed be adjusted. For flight without a motor the trimmer loops can be hooked into the main carabiners, so as to keep the normal EN/LTF certification status.
The Hybrid-Risers have a speed system, which can be used when flying without the motor.
Approved weight ranges *
| DULV | EN/LTF | |
| EPSILON 6/23 | 85 – 130 kg | 60 – 80 kg |
| EPSILON 6/26 | 90 – 145 kg | 70 – 95 kg |
| EPSILON 6/28 | 100 – 145 kg | 85 – 110 kg |
| EPSILON 6/31 | 110 – 145 kg | 100 – 130 kg |
| * Takeoff weight (Pilot, glider, equipment and motor) |
Certification
When used with the Hybrid-Risers the EPSILON 6 has DULV approval for all sizes (without use of speed system) as well as the normal EN/LTF approval. The certified weight ranges are shown in the tables above.
Compatible motors
The certification test flights are carried out with a commercially available motor (Cosmo Infinity Biboxter). Other types of motor can be approved by the manufacturer or the DULV after carrying out an approved compatibility/handling test.
Tests are made with the following engines:
