Guys...I am looking to get a new speedo for my T4 and B4. The T4 I am running mod class with a 7.5 LRP X-11 motor and B4 is stock class with 17.5 Tekin Redline motor.

What is the difference between the Tekin RS Pro and the RS ? The RS says it has a 5 turn limit for brushless and I doubt I would ever be able to run anything close to that due to my skills....probably 6.5 or 7.5 is the most and they are alot of me right now!
