Hey guys I just got a new servo for the steering and was wondering if any of you know what arm will work on it . It is 7.57 mm shaft thx for any help.
 
it's a off brand all metal gear 310 oz toque. I am trying to find a aluminum arm for them. here is the site he lives about 45 mins from me.

I bought one a year and a half ago and another 6 months after that. The first one just went out 2 weeks ago but the other is still running like new. Not bad for 45.00 shipped, the plastic arms that come with it are strong but would like to have aluminum arms.
 
If you measure the spleen with a micrometer and count the ribs, I will check the HiTec's I have and I'm sure someone can measure the Futaba spleen for you and count ribs...If you're lucky, it'll will be one of those sizes.


Since Futaba makes a lot of servo parts for other manufactures 1/8 1/10 etc.., there is a decent chance a Futaba AL one would fit but get a measurement/ count first....
 
I pulled the arm off one of my 5755's...


It has 15 ribs and is approx 7.85mm (its was tough to get the caliper in there, but this is pretty close)


Anyone have Futaba's they can measure for Forist?
 
OK...I went and checked out their website and called their phone #...(Owner sounds like he just woke up or was wacked at 11am..lol)


But....he said that he's not aware of any AL arms that fit and he's put those through some demanding driving this summer with No breaking or stripping of arms...


I must agree in a way...the HiTec's have thick plastic arms and I never really hear of anyone having problems...I think maybe Rob64n a while back...


Looks like for $45 you just buy a new one if it does ever break...
