stupid question on servo

[buggy0001]

I started collecting parts to build a sportsman style crawler and ordered this servo. I then realized that it says its designed to run on a 2 cell lipo. I already ordered a 3s lipo's so will this work?

You will burn it up if you connect it to a 3 cell. Only way is to use a BEC or go to a 2 cell.

ok, that's what I was wondering. I always run a BEC. Do you have to do anything special with the BEC as far as settings?

 

[GodSpeed999]

Yes, program it to run at 7.4v "thumbsup"

Yea, run at 7.4 put in splitter/ bypass to run servo directly off bec.

 

[DRTMI]

If you are going to run 3s, you can up the voltage to the servo to 8v. Just use bypass like JW said above.

Awesome, that's what I needed to know. Thanks guys
