what is the torque in usa.
 Jay D 30 points
Multiply the KG by 13.887 to get the torque in ounces. So 8 x 13.887 = 111.096 ounces of torque.

Hi I bought this servo and the truth came I was very unhappy that did not work, at no cn beware this servo WORKS

depends what you use it for. The stall torque is very low, so cannot be used for 1/8 SC truck steering applications.

Hi, eluminous did you find the working frequency? how did you set up yours?, I'm about to install mine on a hk600, any suggestions?
 eluminous 24 points
Sorry Alagam, I only noticed your question chance. I'll answer just for future reference if people are wondering as I'm sure you have figured it out by now. My 4008 has been running fine along with my Quark but I set it to 1520/250 just to be on the safe side. Anyone else can chime in of they know this servo can handle 333?

eluminous  24 points - 5/11/2012
 
Hi all. Can this servo run at 1520/333 on a Spartan Quark? I am assuming it would at least run 1520/250.. Some info about this on the product listing would be nice.

Is the spline the same as futaba, i just don´*t get why they don´*t ALWAYS print that out in the spec!?

can it run with 7.4v?
 Straight Up 743 points
I would strongly believe that should be OK. Servo voltages are generally "nominal", so specification to accept 7.2V should also be OK on 7.4V. Be careful that a freshly charged 2S Lipo is at 8.4V, which could be pushing it a bit, but even then I'd expect it would hold up OK.
 rydfree 28 points
You could always put a simple diode inline on the red wire and that would reduce the voltage the servo gets by .7 volt. A fully charged 2 cell Lipo is 8.4V so the servo would see 7.7 max . At 7.4 it would still see 6.7v
 Straight Up 743 points
I agree with rydfree's recommendation - a diode takes away all concern.

1N5343BG This is a 5w Zener diode 7,5v. You must know the current draw to know the power needed.

its works great, its fast and strong. Only 1 thing the gears need a bit more grease,it wil run even smoother. I'm verry happy with the servo

First bad servo I've had from Hobby King, with MANY different types purchased. Initial run on the servo tester was very "jittery" indicating a dirty servo pot. I cleaned out the pot (previously done this on other servos without trouble, so I knew what I was doing), reassembled it and it worked OK for about 10 cycles, then the motor seized. Game over.

Well there you go... Not a servo to go the distance that's for sure! This servo lasted for approximately 25 flights on my TZ Frenzy after stripping one of the metal gears which resulted in a total loss of tail control and almost costing me a decent heli crash. After this episode it has lead me to conclude what I first believed to be a radio blackout that caused my first crash 2 months ago in the TZ 50 was in fact more than likely this servo that failed initially. The first crash was a total loss of tail control which resulted in an out of control heli until it hit the deck. It had me absolutely baffled when it happened, but I think it's all just become much clearer now in hind sight. Really disappointing. But a reality none the less.

A great servo. I use them for steering on a couple of my 1/10 cars. Super quick, precise, and decent torque. For the features and speed these are pretty hard to beat at this price. They are also a good height, and fit easly in most 1/10 scale cars.
