R6-R5 Rotor Details and Uses
Rotor dimensions are critical to performance.
PLEASE NOTE: The number one discussion a racer has with me is the R5 or R6 running hot. A new racer to the R5 typically gears the same as their other motors without regard to what the R5 wants for gearing. EXPECT to reduce the teeth number on your pinion by at least three teeth (for example, if you typically run a 30 tooth pinion, use a 27 for your initial testing). Do this, and run a fan, you will see great performance from the R5. The following chart is a suggestion only!
KV Rating: Tested on Motolyser and will vary by rotor size and type installed (all motors tested with 12.5mm rotor diameter). These are actual average values as tested.
SUGGESTED MOTOR USE
*Timing/OAR: Suggested starting point (Monitor temp!). Use motor checker to confirm timing. Will depend on intended use, track size, and OAT!
