Q0. How fast will my R/C vehicle go?

A0. To find out how fast your vehicle will theoretically go with a certain esc, motor, battery and other factors, visit the R/C Calculations web site >> http://scriptasylum.com/rc_speed/_top_speed.html

Q1. What's the proper gearing for my Tekin Redline Motor?

A1. That depends on a few factors. Track size, traction and track layout all play a part in optimal gearing for any motor. We do not recommend running the Tekin Redline motors over 180 degrees(f). Optimal motor performance is found between 125-160.

Q2. What's the difference between the RS Pro and RS?

A2. The RS Pro has twice the fet's than the RS does. This provides it with more power handling abilities for lower turn modified motors. We recommend the RS in all applications that use a motor 6.5 and higher. We recommend the RS Pro for 4wd modified and Mod TC applications.

Q3. What's the difference between D2 Dual Mode and Sensored only?

A3. D2 dual mode utilizes the Sensors to provide the RS with exact rotor position for starting and rolls into Sensored operation providing smoother and more efficient operation. We recommend this drive type for modified racing. Sensored only mode relies completely on the sensors for rotor position and bases timing off of the sensor feedback. This mode is most helpful in spec class racing where adding extra timing is beneficial for maximum performance.

Q4. Will the current limiter effect top speed?

A4. No, the current limiter or LM setting on the RS only limits the amount of power reaching the motor on low throttle inputs. It does not affect top speed.

Q5. How do I change between D2 dual mode and Sensored only?

A5. Currently you must have the Hotwire USB interface device to change between the two drive modes. We are going to add another throttle profile to allow this change to occur on the esc's own interface in the future.

Q6. How hot is too hot for the Tekin Redline Motor?

A6. We do not recommend running the Tekin Redline motors over 180 degrees(f). Optimal motor performance is found between 125-160.

Q7. How do I know if my motor sensors are good?

A7. Simple, the RS and RS Pro have a sensor checker feature built right in. Simply rotate the motor slowly by hand while the RS is on and receiving no throttle input. You will than see the last 3 led's toggle on and off while each of the 3 motor sensor report in.

Q8. Do I have to run the silver cap that came with my Tekin ESC?

A8. Yes, we always recommend using the included silver capacitor that was supplied.

Q9. Does Tekin offer replacement rotors for the Redline motors?

A9. Yes, we offer a 12.3mm(tt2271), 12.5mm(tt2272), and 13mm(tt2273) replacement rotors. click here to view rotors.

Q10. What is the difference between a Pro Crawler Motor and regular Crawler Motor?

A10. The Pro motors are hand wound, have diamond trued comms, and come with our own brush and spring combo. The non pro versions are machine wound and come with standard brushes and springs.

Q11. Why does my Tekin esc flash between led's 1 and 4?

A11. Your Tekin esc is showing you the internal temperature of the unit. Led 4 is displaying neutral throttle while the esc is showing you the temperature in led's on the display. More led's means hotter internal temperature. 1 led being the minimum and 7 led's being the maximum.

Q12. Can I use other companies USB adapters on a Tekin Esc?

A12. No

Q13. What do I need to do to the ESC if I'm using a separate BEC?

A13. You must remove the red wire from the esc's receiver wire harness. Make sure to tape it securely to the harness to prevent shorts.

Q14. My Tekin speed controller won't find neutral during the radio calibration, what do I do?

A14. If you're running a Futaba, KO, or Multiple radio you will need to reverse your throttle channel.

Q15. Do I need to run the capacitor that came with my Tekin speedcontroller?

A15. Yes, not doing so will void your warranty. However, we have special instructions for the G11 esc click here to view G11 instructions.

Q16. Are the Tekin speed controllers waterproof?

A16. No. Water damage is not covered under warranty.

Q17. How do I get a Tekin product repaired?

A17. Check out the Service Request page. You can find information there on how to get your products repaired.

Q18. Where can I find product specifications?

A18. Product specifications can be found on each product page. For older products you can view our product archive specs at this link.
