Seiko vs. SWB 3 rudder tray w/ 5955TG's Help!

[PTS]

I am waiting on a New SD-MODELS 40% Extra 260HP to arrive. My original plan as far as a rudder power setup was to use the SWB Self Adjusting w/ 3 HITEC 5955TG Servo's. I have also been reading about the BIG Seiko as well. From what I gather is that the SEIKO is really not good for IMAC due to a centering issue. All threads seem to lean this way.

I would like to see if any updated information is available regarding the big SEIKO for precision flying. Also if the SEIKO is being used for IMAC, what voltage is recommended?

Please, any suggestions is greatly appreciated.

3 9152 Futaba's in line using the stock tray will work awesome. I'm building the yak right now and used this method. The 9152 works great as a rudder servo because the bigger gear train seems to hold up better.

Hi there PTS, I am not familair with the seiko driver, however I can give a thumbs up to the SWB tray and three 5955's. I have this setup in my super extra and it provides plently of rudder authority plus the rudder always centers in the same spot which is just what you want for IMAC.

The tray makes setting up the three servos so easy, they do not ever buzz when sitting idle which means they are not wasting power fighting each other.

A buddy of mine has had great luck with his Seiko Servo for IMAC use. Here's a link to some pictures.

He powers it with the Seiko Driver battery made by Fromeco. I think it's 11 volts, but not sure.

Thanks for the response(s) Garrett, Benny, and Dave.

Dave has Ralph ever complained of any centering issues or setup issues? The other thing that concerns me is the speed and power of the Seiko, I would assume on any plane. Garrett whats your input on the SD Rudder design? Can it take the constant abuse of the Seiko?

Hello Garrett.

What standoff length is appropriate for the 40% 260 running a DA-150? Also what cannister and header setup works for this plane?

Thanks,

Perry

Lets talk centering.. (just a thought)

On the SWB tray with the cables wouldn't the centering of the tiller arm inherit the bad centering characteristics of "X" servo times 3?

PTS, I am using 3 5955s in a non-self adjusting swb tray in my 42% Dalton, its more than plenty power and then some. Zero centering issues.

Pts, not sure what the right headers and pipes are for the DA 150. If you search on here Craig did a nice little build thread on this same exact plane with a DA 150. The rudder will be fine with whatever you choose. I have flown a few planes with the Seiko and prefer the digital coreless servo better. You don't need to run and extra battery and switch either. Ill take a shot of my Yaks setup using the stock tray built into the plane. Its in there solid and I don't think you will need anything else.

Thankyou!

well I am a seiko guy - why - value - ease of application- power - no centering problems with right setup - have it in 3 of my 40% planes - 46% ulti and SD yak and extra - i do imac and freestyle

I have the SWB self adjusting in a couple of plane and the device is outstanding. I run 3 5955 in my 40% 300 and it has alot of power and centering is always on the money. Give Scott a call at SWB and talk to hime. The Self adjusting set up is very overwhelming until you actually see it work. You do not need a matchbox and if for some reason a servo were to lock into a position you can still fly the plane with the other servo or servos. A buddy of mine just put the seiko in his 40 % SD Yak and Likes it but you do have to run a seperate battery for just the servo. Good luck with the 260 and chosing the servo set up. Tony

I've been running the Seiko for about 3 years and have no issues at all. IMO it's a great servo and simple to install and setup. I use dual batteries ( 5600ma li-ions ) - one battery is T-tapped and runs to the Seiko and the other lead goes to a Smart-fly regulator, the other battery goes directly to the regulator. Never had a power or battery issue with this setup. Tons of rudder power ( 40% Carden Edge ) and no centering issues - This is my primary Imac plane and I have the same setup in a 40% Carden Cap.

Ok, sounds like the are equal in performance, but how about a weight of each setup.

A pro about the SWB is you have tripple redudance against failure.

Just had a new seiko out of the box with an intermintant problem of not working. Opened it up and found 25% of the pins on the IC chip to be "solder-less".

The guys with the SEIKOS, how are the rudder hinges holding up to the speed and power?
