Tahmazo has developed a new Contra Rotating Motor and it was used at the F3A World Championship in Argentina 2007.
Flown in the model-Seduction WCR (designed by Tom Takamatsu from OK Model), the motor was powered by 2 packs of Tahmazo WC Series 6S 4000mAH lithium packs, Tahmazo M8132-3S speedcontroller and Custom 15x12 Contra-Rotating propellers.
With this new F3A contra rotating motor, the Seduction WCR weighing 4.78kg(including battery pack) was able to complete the FAI P-07 schedule with the 6S 4000mah WC series battery pack.
