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
