I'm building a new Pattern plane for next season and have been trying to figure out the data on the new 3 pole digital servos. The deadband on the both the cheap 3 pole digital servos and the coreless digital servos is 1 usec while the deadband on an expensive coreless analog servo is 4 usec. The update frequency of the digital servo is 300 hz while the update frequency of the analog is 50 hz. Doesn't this mean that the digital servo with the 3 pole motor is going to center better and have more holding power than an expensive coreless analog servo? What advantage does a coreless digital have over a 3 pole digital?

(Specs are from Futaba 9402 analog and Hitec 5475hb digital servos) Couldn't find any info on JR servos.

Thanks

A lot of the experts will be responding to this one but from what I have found out and from my questions to Hitec, the higher update of the digital will make the 3 pole digital respond faster and have a stiffer feel than the analogs. Away from deadband, it takes more error for the analog servo to come up to full power compared to the digital servos.

That is such a good question= am am waiting to hear more from the experts!

Maybe in the radio forum you'll get more answers.

Thanks Robert. I just posted the question on "RC Radios - Receivers - Servos" Forum. Maybe I can find an expert or two there.
