5Pack SG90 9g Servo Motor， Micro Servo Motor SG90 Mini 9 Gram Servo for Arduino RC Robot Helicopter Airplane Car Boat Controls

Basically the standard for servos is that the PWM will range from 1ms to 2ms. This one expects it to vary from 0ms to 2.5ms which is unheard of and so basically you will not have any luck getting it to do the full 180 degrees but only the 90 degrees that a typical PWM output is made to do. This is not normal and this is not a real SG90 which is only made my the TowerPro company.

Liked the prices, only been using for a short while, shipping as always superior.

I received the 5 servos undamaged and on time however, none work. I tested them on 2 known to be working Spektrum RC receivers but none of the servos work.I’ve been in the RC hobby for many decades and I’m very familiar with RC equipment.Thank you for your attention to this matter

These motors don’t work.
