Are there any traxxas transmitters where you can change the throttle limits on the fly? I know most Spektrum transmitters have a 50/75/100 throttle switch.
I personally don't use a gyro as it creates more problems than it solves for me. Also, without a gyro, you can learn to control your RC better. The Flysky GT5 does have a gyro though, but it can be disabled or enabled easily.
