These are the new HQ Prop 9 x 5 high RPM props (31 Aug 2013) - a matching set of 1 x CW(R) and 1 x CCW(standard) low pitched multicopter props. These are specifically matched to 1175kv CarbonBird motors on 4S 16.8v or the 888kv CarbonBirds. We have tested them to 10,500 RPM and amazingly - They require almost NO balancing - They are tough and quite. they are amazingly similar to the Graupner E-Props in that they have a strong centre airflow and good motor cooling.
