Fantastic servo, been running them on the ailerons since September. Very tight gears (virtually no slop when new), and very smooth and accurate.

I noticed that Akiba was running them on elevator and rudder at the Worlds, so they would be good as an all purpose servo. I would choose these over anything else Futaba has at the moment.

I have some BLS 351's on the way but I doubt I will get to try them until spring now
