Revell 24084 Control - remote controlled RC airplanes - Micro Heli "prion" RTF / GSY / GHz / 3CH (Toys)
Unfortunately, I must add my voice to previous speakers in part, have something of Revell expect else! For me, the top rotor is after 10-12 boots also completely failed (without major crashes), he allowed himself to push again, then he ran no longer.
