Designed specifically for smooth power delivery for all track sizes and conditions, these rotors will work in R4 and R5 Team Power Products motors. Comes in protected tube with extra shims. If you buy a new R5 motor, and choose the 'Extra Rotor' option, the rotor price is discounted at time of purchase! NOTE: These rotors require experienced motor build skills to install correctly. As with all competition components, there is no warranty!
I now have five sizes of rotors available for the modified winds (12.0mm, 12.3mm, 12.5mm, 13.0mm, and 13.5mm). Each have a purpose:
| Rotor |
Description |
| 12.0mm TPP55120 |
-
12.0mm - The smallest option rotor I have. It has a specific purpose: high speed on large smooth tracks. Can work with low wind motors to reduce torque but have high top end. The acceleration out of corners will feel 'very soft'. Requires re-gearing and re-timing to assure motor cooling.
|
| 12.3mm TPP55123 |
-
12.3mm - More traditional of the smaller option rotors, more torque than the 12.0mm rotor. If you need the high speed of 7.0, 7.5, 6.5, 6.0, and 5.5 motors but need lower torque to keep from blowing tires away during cornering, then this rotor is the ticket. Top end will be increased and torque will be reduced, compared to a 12.5 rotor. Acceleration, especially low speed corner, will be 'soft'. Requires re-gearing and re-timing to assure motor cooling.
|
| 12.5mm TPP55125 |
-
12.5mm - The most drivable modified rotor with good torque for most tracks and conditions. The 'standard' ROAR rotor size. Recommended starting point for ALL motors except the 25.5 wind.
|
| 12.5mm TPP57125 |
-
12.5mmStk - Standard rotor for 'Stock Spec' motors to exact ROAR rules for use in classes specifying 21.5, 17.5, 13.5, &10.5 'ROAR Stock Spec' motors. Shorter than the modified TPP55125 rotor above used in modified classes and less magnetic field.
|
| 13.0mm TPP55130 |
-
13.0mm - Option rotor best used in 5.0, 4.5, 4.0, 3.5, and 3.0 drag motors. Have tested them in higher wind modified motors (7.0, 7.5, 6.0, 6.5) on oval tracks with good results; top end will suffer but pulls hard out of corner with an amp draw increase. This rotor out torques the 12.5mm rotor by a large margin, will need to use the ESC to add timing as the car speeds up for best results. Careful monitoring of temperature is important. Requires re-gearing and re-timing to assure motor cooling.
|
| 13.5mm TPP55135 |
-
13.5mm - Monster torque in option rotors! The airgap is just .5mm (about 0.020"), which really puts the torque to the road! Definite loss of top end unless you use the ESC to bring timing in as RPM increases as well as a major leap in amp draw. Use this rotor for drag racing in 4.5, 4.0, 3.5, and 3.0 motors. Requires re-gearing and re-timing to assure motor cooling.

I have a couple of R4 5.5 motors that absolute beasts in my foam tired cars and was looking for a way to tame them a bit. I was thinking a weaker rotor but not sure if it would be the right thing to do. After reading the descriptions of all the rotors I decided to try a couple of 12.0 rotors. After the install I have run a couple of races now with my mod wedge car, and this is the most driveable it has ever been! The rotor change worked much better than I expected!

I ordered a 13.5 mm rotor. There was a problem with a defect and they replaced it no questons asked and i received it in a coule days. Definitely a place that stands behind their product. A very rare thing these days. I will defenitely be purchasing from them again for next seasons motor. Very happy customer here. Thanks again for the great expirience.
