Typhoon motors are wrapped on Green-Coated 3-Lam Blanks.  Axle and Lamination ODs match the Aurora Gray-Lam motors.  They can be substitued in any Aurora or similar pancake motored car.  The balance on these motors is very good but is not guaranteed. Most will be well balanced but a small percentage will be out slightly.  All Typhoon motors will run TFX chassis well without balancing.  If the TFX magnets are upgraded the balancing becomes more important. The ohms are very well matched pole to pole.  Our testing showed that on a random batch of (20) 16.5 ohm motors the measured resistance at 70F was between 16.4 to 16.6 with only one reading 16.7. Pole to pole variation was 0-.1 ohms on all motors.  Typhoons are wrapped with color coded wire to make it easier to identify them and assist in determine legality for certain classes.
