[NSRCA-discussion] Rudder servo arm

[rcmaster199 at aol.com]

Thanks Vince,

Didn't realize that JR offers the carbon composite heavy duty large arms. The price is actually lower than the DuBro. I'll have to get some of these next time I order

JR has something similar.  It is HD 2" also.  Here is the reference:

I have been using this one for years with good results.

Derek,
I always found that the extra large, round black servo wheel that comes with Futaba servos would give me 35+ degrees of throw. For JR servos, I cut a round phenolic disk and screw it to the top of their round servo horn to make it the same size as the big Futaba horn. As I recall, the large Futaba horn is approximately 2” od.

Does anyone have a preference as to which servo arm one should use to enhance the throw for rudder?  I've seen different types - some that are made out of PCB material and bolted/screwed to a round servo wheel so that the arm is about 2" - 2 1/2" long... I've also seen the metal ones that replace the servo wheel/arm that comes with the servo.

 

BTW, these need to be for Futaba... and should weigh as little as possible.
