So the T4 I bought to get back into racing came fitted with a Bruno servo

A BR1-T4 WC v1 to be exact.

I’ve tried searching on the site but can’t find much info on the servo.

The site lists the servo as having a Bec voltage and speed at 6.0v. Can I set this higher?

Also I’m running it with a NB4 Pro, it says it’s digital but nothing mentioned about optimal frequency/hz.

Any info or advice here would be appreciated.

Or do I just get a power hd s15
