Our Story Expect more from your 9g servos!
9 gram servos are used in a wide swath of RC devices. The can be found in RC planes from 600mm to 2400mm. In the past few years we’ve asked for more from these planes, loading them up with Lithium Ion batteries and sending them out great distances. We’re adding extra weight and or asking the control surfaces to be pushed to their limits. This is especially true when dealing with elevators, and elevons. And though your plane may weigh nowhere near the 2.6 kilos these servos are rated for, when you factor in the G-force of a dive and the weight of your craft, you’ll want plenty of overhead. You don’t want your servos giving up just when you need them most. Why 7.4 volts?
There is a relationship between power, speed and torque. If you’re running your plane from the 5v BEC from your ESC you’re drawing 5 volts for your servo. If you can step up to 6V, you’ll get a bit more speed and torque from your servo. That may mean that you should supply a seperate 6V power supply. When you do this, you not only get more power, but you’ll get more amps. The BEC in most power supplies are linear and only provide around 1 amp of power. Not only are your servos drawing from this 5v/1amp power supply, but so is your receiver, LED and anything else hooked up on the 5V BEC. What this also means is if you draw too much power all at once and kill the BEC, you’ll have no control. Thus, a better BEC is often needed. Especially if you have 3 or more servos. A suggested UBEC is the Henge UBEC, it puts out 7.4v at 8 amps. Please make sure your receiver accepts 7.4 volts, and DO NOT power your receiver with both 5v and 7.4V. If you need more information about this, please message us.
What you’ll pick up with 7.4 volts is a servo that is at peak performance for it’s class. It’s rediculously responsive, with ultra smooth control. If you’re aiming to build a top notch plane, you’ll love 7.4 volts! INAV/Ardupilot Matek Wing Flight Controllers
If you’re working with INAV/Adrupilot Matek Wing Boards, many of them have 7.4 HV (High Voltage) options. The following flight controllers have 7.4V (marked as 7.2V) built in.
Matek F405-Wing (EOL)
Matek F722-Wing (Discontinued)
Matek F765-Wing (Discontinued)
Matek F765-WSE
Matek H743-Wing (Versions 1 and 2)
Matek FCHUB-W (Used with F405-STD, F722-STD-both EOL)
Note: The default voltage for the above is 5V. To get to 7.2v out you will need to solder a bridge. Go to Matek’s website for more information. But the bottom line is, if you have one of these flight controllers, why not upgrade your servos to maximize performance? Why the terms “Metal Gears” and “Digital” make a difference. Metal Gears
– The term “Metal gears” gets thrown around loosely. There are plastic gear servos which are fine for very lightweight aircraft and rc cars. But once speed and weight become a factor, the plastic gears can easily strip, leaving a plane unflyable or a car undriveable. Metal gear servos are a step up. But, there are different levels of metal gear servos. Sometimes not all the gears in metal gear servos are metal. There are different types of metals and weights to the metals. Getting a good metal gear servo is important for planes that are performance based and for longevity of a servo, especially if it’s going to be put to the test. Digital
refers to how the servo takes a signal from something like a receiver or flight controller and turns it into servo movement. An analog servo gets its information 60 times in a second, while digital servos get it 300 times in a second. This leads to smoother servo movement which you will feel while flying or driving, and it adds to more torque and more holding power. It seems silly to think that things like higher voltage, metal gears and digital make a difference. But, once you try these servos, you’ll be hooked. Authentic JX Servo
-JX Servos have their own factory and produce $30 million worth of servos a year for a variety of applications including the automotive, healthcare and industrial segments.
Names like Hitec, EMAX and other are more familiar because they manufacture other things such as motors, electronics and sometimes cars and aircraft. JX only makes servos. But, for those in the know, it’s a well regarded, well respected name. As an authorized dealer, we are providing you with the legitimate product straight from the factory, at reasonable rates, without having to wait.
