3.3v TTL to control PSC?

I understand that the PSC requires a 5v TTL signal for serial communication, but would anything wierd happen if I use a 3.3v TTL serial signal to control it? I seem to be able to control the servos at low speeds fine, but what about high speed?

    Hello,

    ·· Regardless of how fast the servos are moving the PSC communicates using serial, and the rate of communication will remain consistent unless you change the baud rate.
