In the "touring scoop" section of the RC Car Action's latest Touring Car magazine, they have shown the new Futaba S9550 Digital Servo. They state that Futaba claims this is the ultimate touring-car servo for nitro and electric applications. They also wrote that it was the same servo used by Surikarn Chaidajsuriya to win the recent IFMAR ISTC World Championships in South Africa.
I think this servo will be great for my Reflex since the servo in the Reflex (and many other 3-Belt nitro touring cars) has a direct steering system that is mounted to the upper-deck and the very low-profile design of this servo will really lower the car's overall CG.
This servo is rated at:
Speed- 0.11/60 degrees at 6 volts
Torque: 80.5 oz.-in
(5.8kg/cm) at 6 volts)
But I have a few questions though. Will this servo be powerful enough for a 4WD nitro touring car? It seems like a great idea but I don't want to put an under-powered servo in my car. The Reflex like I previously stated has a direct steering system so when the car hits any bump in the road the force is directly transmitted to the servo. Will this servo be able to handle this abuse without failing or breaking?
Does anyone have any experience or know anyone who has had experience with this servo? How is its performance in an nitro touring car? Will it provide an ample amount of torque or is it kind of on the short side of power?
I looked on Futaba's website about this servo and their description of it has no mentioning of any particular use for RC cars. In fact, here is the exact description:
"Low profile design allows the servo to fit into wings and lay down down in car chassis for less obstruction."
This is what is kind of confusing me. Could this servo be used effectively in a nitro touring car like RC Car Action stated?
I use a JR-R1 PCM Radio with the R330S 75MHZ 3-Channel SPCM Reciever. Will this servo be compatible with my radio system? Also, Futaba uses a "different" shape wire plug. It has a little "ear" on it that the JR plugs don't have. In my experience Futaba plugs don't fit into JR receivers. So I think I am going to have to change the plug or cut the "ear" off. Does Futaba make a version of this servo to fit JR recievers? I use a Futaba switch with my R330S receiver, and in order to make it fit in the receiver slot I had to cut the little "ear" off the Futaba plug to make the plug perfectly sqaure (the reciever slot on JR recievers is perfectly square). I am thinking I might have to do that with this servo if I purchase it. Only problem is, if I screw up a switch costs $6 and a new servo costs $90! Would you advise to do that to make the Futaba plug fit to my R300S receiver?
Thanks in advance!
