Default Servo question

having the tt01 model, if you upgrade all the plastics with alloy hop ups, and insert a new faster turn motor, does the servo and receiver need changing as online i have seen 27 mhz and 40 mhz was wondering what the different in mhz does, is it better and control with faster response???

any light shon will be greatly appreciated

The 27MHz and 40MHz only applies to transmitters and receivers, and you simply have to have a matching transmitter and receiver, no need to change if you just want to hop-up your car. The only time you would need to change receiver is if you get a new transmitter.

Your servo will operate fine with a faster motor and some hop-ups but with everything, some are better than others. In touring cars you should look for how fast the servo turns through 60 degrees, anything faster than 0.10 seconds is a very nice servo. Fast is good, but by no means necessary if you are just hopping up a TT-01.

For a TT-01 don't worry about upgrading the servo unless you are putting down serious power.
The radio frequency doesn't make the car faster or slower in response by itself. The modulation makes a big difference for interference. With AM, you will get interference and twitching from all slorts of things around you, with FM hardly any interference (I get zero and race next to a highway and airport), and 2.4Ghz (DSM) is almost faultless.
If you are doing fine with the 27AM radio, keep using it. If you get a high power brushed motor or anything brushless, you will need either FM or DSM, the AM will play up bad.
