We have also developped a 550 size version of our new VST2 Pro motor. There are four different winds available and a 4
poles 4000KV outlaw version. This is the motor to beat for short-course trucks and other oversized off-road cars.

Features
The Short Course category has become a very popular racing class. Thanks to this popu-
larity, the cars have evolved, increasing the performance levels and allowing the use of
more powerful motors and batteries. As with all Vortex racing brushless motors, the 550
size VST2 Pro has been extensively tested by our world championship winning team. This
ensures that you get a motor that has all the right characteristics to give you an edge over
the competition. This motor has the same features as our new 540 size VST2 Pro motors,
but it uses a longer can, longer magnet for extra torque and a 5mm shaft. Available in dif-
ferent winds from 4.5T to 7.5T
