Hi Guys,
The Spirit Pro can have an input up to 15v on AUX1.
Is this regulated down to 5v or 6v before going to the servos?
Or is it just passed thru untouched?

The input is on the same bus as the servo's, so 12v in, 12v out...

It has built-in regulator, but not for the servos.

that's not a bummer, is a flybarless
what you are looking for is called BEC/SBEC/UBEC :-)

What I mean no point having a 15v input if it is just going to burn out the servos

At least it won't burn the unit at the same time :lol:

there are good tests out there regarding reverse current generated by servos... induction voltage being up to almost 15v... so good to be safe on Spirit side. the unit is protected of being damaged (less likely - short peaks only) but most important: protected of malfunction (crash/reboot in flight?) as it is proof against peaks of up to 15v. brownouts / malfunction due to reverse current is a well documented problem...

... and maybe some day in the future we will see shv-servos (Super HV)... i.e. 12V or even 15V ;) great to be prepared!
cheers

What would be the advantage of a HV Power supply for a Spirit unit with 6V Servos connected to it, protected by a regulator?

For scale helicopter I need to configure my system the other way around.
I'm using 8.4V HV Servos for swash plate and tail rotor, but for a retractable landing gear I want to use 6V standard servos.
A Y-connetor and a BEC takes care of the 6V servos in an extra voltage branch.
