## Questions & Answers

**Q: Does the pulse width need to vary beyond the range produced by a typical hobby receiver to get the full 270 degree rotation?**
A: Yes,you're right! Generally speaking, the output pulse width of the remote control is in the range of 1000-2000,so the displayed angle is 135 degrees;To get the full 270 degrees rotation, the output pulse width should be 500-2500.  :)

**Q: Will this servo fit a traxxas rustler?**
A: Yes,this rc servo can fit traxxas rustler

**Q: What are the motor arm dimensions? What size are the holes in the arm? Are they clearance holes or threaded? Where are the wires located on the back?**
A: Thanks for your question.Servo Arm is 25Tooth,they are threaded.More info please contact with seller.

**Q: my esc has output voltage of 12v can work with 12v?**
A: It's not ok cause the voltage is too high
