[NSRCA-discussion] Futaba Servos

[krishlan fitzsimmons]

Yep. I made my own though. Didn't know they were available anywhere. Thinking about it after I did it, we really only need the + and - coming out of the receiver from one lead, not both. Correct? Or no?  Obviously we need it split back out to two +'s and -'s back at the servo's though.

>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.
