The stock Hornet had plastic head a little brushed motor with 8 ni-mh battery (9.6v). It had not the autorotation system. So the performance were low. Then with brushless motor and lipo battery (3s) all changed with full 3D capability. Lots of upgraded then were released by mscomposit and other little company.
They flew very well, and now i have to restore them for a new life.
