Spektrum A7040 HV Retract Servo

Looking for a retract servo for your giant-scale aircraft? The A7040 is just the ticket.  A high-voltage, fully proportional servo, the Spektrum A7040 is perfect for pilots who want a retract servo that can be powered by a 2S battery without a voltage regulator.  The A7040’s fully proportional design allows for end point adjustment and speed adjustment for scale-like gear movement.

  • Low-profile design is ideal for larger aircraft
  • The A7040 will draw low current, saving battery power
  • 270 oz.-in. of torque is great for models with heavy wheels and gear

It costs $35.99.
