TFX Typhoon Motors
Typhoon Motors were designed for our TFX Chassis. They are a direct replacement for all Aurora Thunderjet/AFX/MT chassis, .0635" shaft diameter. Similar aftermarket chassis may have smaller armature holes in the gearplate and may require reaming for proper fit. Checkout the Specs page below for more details. Only the 16.5, 18 and 20 Ohm motors are available in the RTR TFX Chassis. Checkout the TFX Upgrade page to see the entire lineup of Typhoon Motors.
Specs
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. It is NOT recommended to run any unbalanced motor, including Typhoons, with Black Dragon Magnets. 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.
Red Wire is for Hot Stock/Drag motors
Green Wire is for Super Stock racing
Clear (Copper) Wire is for motors whose ohms fall outside normal racing rules but still have their uses in panckae motored chassis.
16.5 Ohms - These motors are wrapped with Green Coated Wire and are equivalent to the Aurora Gray-Lam Thunderjet motor.
20.0 Ohms - These motors are wrapped with Clear (Copper) Coated Wire. They are intended for the TFX chassis to make the car extremely easy to drive. Great for very tight tracks, rough home tracks, novice drivers and tracks where the voltage is too high for 16.5 ohm arms to run without brakes.
