Pioneer 4
High-Level A with B-Upgrade
The Pioneer 4 stands for the High-Level A segment: lots of performance, generous safety reserves and precise, balanced handling.
The special feature: With the Speed Limiter, which can be installed or removed in a few simple steps, the accelerator travel can be adjusted. With Speed Limiter, the setup remains clearly A-oriented. Without Speed Limiter, the Pioneer 4 unfolds noticeably more speed and dynamism in accelerated flight – positioning itself as a basic intermediate in EN/LTF B.
Thus, the Pioneer 4 combines two setups in one wing:
A-setup for safe entry and comfortable feeling - B-setup for more performance, whenever the pilot is ready for the next step.
Pioneer 4: Fly EN A - then unlock EN B
- High-level EN A with a B-boost: In A configuration, strong performance with plenty in reserve; without a speed limiter, accelerated flight delivers noticeably more speed and dynamism
- Mini-ribs for extra performance: a perfectly finished trailing edge for clearly improved glide and speed
- Extremely durable fabric: PU-coated on the inside, silicone-coated lightweight 20D fabric on the outside
- Precision diagonal ribs for excellent profile fidelity
- Easy-to-sort line layout with clearly labelled risers
- Shark-nose design: shape-stable leading edge with robust, replaceable plastic rods
- High-quality, low-friction pulleys; brake-line pulley is ball-bearing mounted
- Precision manufacturing at one of the world’s most advanced production facilities
