[NSRCA-discussion] Futaba Servos

[Ed Alt]

Sorry, I meant to say common power leads (+ and - ) for both servos.  The only unique lead is the signal lead.  Test it well before flying.

  You run 1 ground wire for both. If you do this, test it well for interaction between the two servos.

    What was the servo extension wire trick? Separate the power wires from signal or something?

    If you are not trying to be brand specific, and it's going in an electric, I have been using the Airtronics digital 94761's on ele's and aileron's for 2 or 3 seasons now. Not trying to sell you on the one's I use, but they are an option to save weight if you need it. I think they weight .80 ou. and have 66 ounces of torque at 6.0v.  I am also running the newer 746's though and they do feel a little different in a better way. The 761's had a great fast snap and a quick stop to the snap. Can't say I noticed any difference between the two on the snap. 

    Where else have you tried to save weight? 
    If you do the servo extension wire trick to the tail, you will save approximately 8 grams- .30 ou.. 

    Good luck with whatever you purchase.

    Thanks for the responses guys. I have a couple of JR 9411 SA for the
    ailerons to swap out but was looking for something even lighter if they
    would work. I need to get about 4-5 oz. Out of this bird.

    I've flown the same design plane, one with 9650's and the other with 9151's,
    and there was a difference. The one with the 51's was a 
    much better (predictable) snapping plane. The 50's were speed sensitive
    (downlines were never the same).

    Andrew is right about the low profile Futaba's. I was running the BL-551,
    1.6oz, 
    (http://www.futaba-rc.com/servos/brushlessservos.html) in my Integrals and
    now in my Valiant. The 9551, 1.6oz, 
    (http://www.futaba-rc.com/servos/digitalservos.html) is the non-brushless
    version (that Andrew was running in his Integrals). The JR 
    9411 will also work fine, I just don't have experience with them.
