Viper R/C enters the 550 motor game with the all new VST 4.5XL and 5.5XL 550 class motors. The VST-XL series coupled with the powerful VTX10R esc makes an optimum setup for your 4×4 short course.
The VST-XL series have been in testing and development stages for many months with top level drivers such as Billy Fischer. Billy’s power systems have been both extremely powerful and reliable even under the toughest racing conditions at the Silverstate and Cactus Classic.
The shipment is expected to arrive in mid-June, 2011.
