Default RE: New Servo - Futaba BLS171HV


ORIGINAL: atul


Jim,

How bad is the centering problem with the S9070SB? I've just purchased some HV Servos for my first Futaba 18MZ project (a Naruke Aries, which I've just completed). Naruke's suggestion was to use the BLS 174HVs for Ailerons, BLS 175HV for rudder (though, IMHO, the BLS 171HV will be more than sufficient for the rudder as well) and S9070SBs for the elevators. I was planning on using a BLS 171HV for the throttle but decided to switch to an S9020SB for the throttle instead. If there's a centering problem with this servo, do you think its better to switch to the BLS 153 instead? I'm not sure whether the BLS153 can handle 7.4V though and all the other servos (BLS 174/175) required 7.4V.

Thanks,

Atul




The centering was bad enough that I decided not to use them for elevators. I selected the JR 3711HV for elevators as I couldn't find a small Futaba HV servo. I used the BLS171HVs on rudder and ailerons. The throttle servo is probably not critical.
