Voltage for gyro??

[Bone]

Hi. I am wondering if I will have to have a voltage reg. to put a futaba 401 on a blade. Also, would I have to for a trex 450se? I think I may trade the blade on the trex, and will want to take the 401 with.

The internal BEC on the Rex's ESC will do it all... No voltage reg. required.
