That's one insane servo, the Savox SB-2290SG!
A game changer? I'm guessing this thing will flip the Kraton over on it's back from a stand still!Can't wait to get my small 2s packs to power the servo. Should be a game changer on this truck.
Is there a reason why you are adding a 2s battery to power the servo instead of running an external BEC?Can't wait to get my small 2s packs to power the servo. Should be a game changer on this truck.

I might have to try that in the future sometime. I just added a Castle 20 amp external BEC and was curious as to your reasoning. May be a dumb question but is there a wiring diagram for using an external battery like you are doing?Actually, yes. I have learned from a large scale aircraft builder that servos will deliver better performance and last longer when directly powered off of a battery. This guy powers his servos in 5k to 20k airplanes with 2s lipo power. The power from a BEC is very dirty. Basically all it is, is a few FETs that are switched on and off very rapidly to give the effect of lower voltage output. BECs tend to get very dirty during peak amp draw. Voltage can sag and the square wave can get ugly. That can cause problems for the electronics onboard of the servos. A decent battery will eliminate all of those problems and should yield a long life for my servos.
The weight is negligable on the heavy kraton. I'm using a 2s 950 turnigy pack. Testing will tell me how much runtime I will get out of the rx pack.

Technically a 2s Lipo is a 7.4v battery. I am not 100% sure but I think that the batteries are rated nominally and not peak and I wonder if servos are rated the same way.Isn't that a 7.4V servo? I wouldn't dare to put 8 or more volts through a $160 servo..,
