  • Retract servo with adjustable endpoints
  • High-voltage compatible
  • Slow transit speed of 1.39 sec/160° at 7.4V for realistic landing gear operation


The A7040’s wide stance and low profile design along with its heavy duty metal gears, cored motor and class leading, 266 oz.-in. of torque, is ideal for mechanical retract systems. Its ability to accept a higher voltage from a 2S Li-Po battery makes setup simpler and operation more efficient. Fully proportional with endpoint adjustable, when paired with a servo speed function, the landing gear movement can be adjusted to simulate scale applications.
