Hi,

I'm running Futaba BLS servos on my 2m bipe. BLS153 on aileron and elevator, and BLS 451 on rudder. The Emcotech regulator switch is adjustable 5.9V or 7.2V.

These servos are not HV servos. Looking at the Futaba website they are rated for a voltage of 6V.

I'm aware that several pilots are running these servos at 7.2V which significantly increases their speed and torque. The difference is noticable.

I can appreciate that it would not be good to run these servos off an unregulated 2cell lipo as I expect that the full charge of 8.4V would be a problem. For that you would need to use a HV rated servo.

What are the experiences of running these BLS servos off regulated 7.2V? Any failures or issues that could have been associated with running at this voltage?

Regards
Clint

I have been running the BLS153 servos at 7.0v this year without any problems yet. Maybe around 100 flights so far.

Thanks Chad. That's good to know.

Clint
