P.Y.Tang have recently tested another Orca range motor, this time the Orca RX-2 6.5T Professional Brushless Motor. The Orca RX2 6.5T was equipped in the Xray T3 for the Racecraft Infinity track in Singapore. A comparison was also tested to the Orca RX2 5.5T, both motors with turbo boost on. The Orca RX2 5.5T was definitely faster on the long straight but the Orca RX2 6.5T was a little easier to drive in the in-field with more consistent and tighter driving lines. The powerband on the 6.5T was much nicer to drive at a small size track. Both fastest laptime were recorded at the 14.2sec on a hot sunny day. The top end speed of the Orca RX2 6.5T was also slightly faster than any 4.5T motor on the long straight. The Orca electronics were running very cool where the Orca Vritra ESC was recording at about 50degC, Orca RX2 5.5T at 65degC, while the Orca RX2 6.5T barely reaching 55degC. A motor fan was mounted during the race. The Orca engineers did a great job in the development of these Orca combinations providing a more efficient and lower operating temperature electronics.
