    I am having trouble soldering a spektrum 4649t serial rd to a sp racing f3 deluxe fc. I have it all wired to uart3 but the rx will not power up. This rx requires 5volts. Is uart3 5volts? I do not have a multimeter to test

    The simple answer is to get a multimeter and make sure.

    It's nearly impossible to do any work on a PC board without a multimeter , double checking is always best don't with the right tools, sometimes the obvious answers is the right only one. But a pic might help.
