Hi Guys,
The servos perform reasonably well. Our tests were relatively simple,
just a set of 3d printed control wheels of 1, 1.5, and 2 cm diameter, fishing line, and calibrated masses.
We tested the servos at 50% and 75% their rated torque for 100 hour, and both the plastic and metal frame servos survived.
The also seem to be physically interchangable with Hobby King TGY-S712G servos for which we already have custom CNC milled frames.
Based on these results, I am going to recommend using Feetech servos for our production aircaft.
You also can try.

The advantage of Serial bus servo scs15:
1.Beautiful wiring structure,
2.Easy to control signal,
3.real-time feedback of position,tempreture,speed,voltage,Current data,
4.Less occupied port.
5.Digital transmission signal is
Flexible, convenient, reliable and good compatibility
Now PWM is Simulate Transmission,Pulse width variation stand for control vector,so easily interfered by the outside world.
Minimalist wiring / occupied port less / more precise control / feedback position, temperature, load, speed and voltage data / support TTL/485 protocol / interface / protocol development mode (multi support mode and servo motor mode) / double link easy wiring / bus connection group of chrysanthemum theory can be up to 253 ID / high precision metal gear group / baud rate up to 1M. Customizable magnetic coding / high precision (4096 bit)

FEETECH New Humanoid Robot Profile
Feetech Robot FT ROBOT Show Motion Group Control (3 min 51 sec)

The FT-17DOF-SC-RTP is a ready to play humanoid robot which comes fully assembled & completed from our team at FEETECH.

This humanoid robot uses 17PCS FT-SCServo (SCS15).
SCS15 is all metal gear and uses TTL level Half Duplex Asynchronous UART BUS Communication Protocol. It gives the feedback of the data relevant to position, voltage temperature, load and speed.

This humanoid robot uses all aluminum alloy parts, anodized color (red, blue, white for optional) or an assortment.It is simple wiring and makes assembly and disassembly fast and convenient.

It is easy to use "MOTION" editing software for Windows system. As long as you use a computer you will love playing with this humanoid robot, even if you do not have any programming knowledge, you can edit the humanoid robot actions within ‘MOTION’ editing software.
Robot hobbyist can move the robot in a variety of different poses by hand, then read in and save data from robot joint SCServo via software, moving through the posture sequences from one by one will complete the program of series motion or dance. The data of dance or motion group can be saved into your local computer for use the next time, or download into the robot control board for offline operation.

The 2.4G remote control system is based on Arduino open source, users can freely modify according to our Arduino source and...Continue Reading

Another good option of 1/10 off road?

FEETECH servo company have annouced that they have newly developed a specially-made high voltage digital servo FT5610M for 1/10 nitro.

Here below is the specification:

Low Profile 300 Degree Rotation Digital Servo FT5610M
Dead band: 2μs
Control System: +Pulse Width Control
Working frequency: 1520μs / 250hz
Operating Voltage: DC4.8~7.4 V
Operating Temperature Range: -10 to + 60°
Operating Speed (6V): 0.11sec/60°
Operating Speed (7.4V): 0.08 sec/60°
Stall Torque (6V) (125.2oz/in)
Stall Torque (7.4V): 11.8 kg-cm (164.2oz/in)
Potentiometer Drive: Direct Drive (300 Degree) (180 degree Coming soon)
Dimensions: 40.5X20.1X28.7 mm
Weight: 49 g (1.73oz)
Connector Wire Length: JR 300 mm

Digital servos features: Support high voltage;Waterproof; Plastic case, resist heat and corrosion; Aluminium middle hull, easy to eliminate heat;Adopt high quality coreless motor.

It would be another good option for 1/10 buggy, LOL.
But since the torque is only 11.8kg maximum,installed as the throttle could be perfect
