Introduction
Combining the compact size of a classic balsa free-
flight model with full 4-channel control, the Piper L-4
Grasshopper 250 is an exciting alternative to the usual
park flyer experience. Its exceptionally low parts count
and time saving features like the magnetically-secured
plug-in wings make assembly about as easy as it gets
for an ARF.
In the air, its docile flight characteristics and gorgeous
scale appearance will reward you with one of the most
enjoyable park flying experiences available. Plus, it’s
small enough and slow enough to fly in a large indoor
venue whenever the park isn’t an option.
