COMMENTS The BLS256HV is designed only for gyro rudder control. Dead band is

servo may jitter. This condition is normal.
Very high current drain is normal at startup. Always use a 6V - 7.4V
battery.

That's not the servo he asked about.

Center pulse is 1.52ms. As for frequency I know for a fact the servo will tolerate 285Hz.

Thank you both for the reply!

Futaba finally called me back but i wasnt happy about the service. Guy was a total jerk off and rude, and took a while to respond.

Anyways, yeah he told me 270 and 1520. Seems pretty close to what you mentioned so i will go with it!

Thanks again!
