Introduction

Think of it as the only autopilot that comes with a COMPLETE set of primary flight instruments for free! Adding servos to any Dynon SkyView System or D10/D100 Series EFIS turns it into a full-featured dual-axis autopilot at a total cost that is comparable to other autopilot-only solutions.

Every Dynon autopilot can fly magnetic heading, GPS ground track, and horizontal NAV from any connected compatible radio* or GPS. In addition to being able to hold altitude, even the least expensive Dynon autopilot can fly to a new altitude and level off once it arrives. Additional standard features include emergency 180-degree turn capability, control wheel steering, and standard trim sensing and annunciation on all servos used on the pitch axis. And because Dynon’s autopilot is built on its best-selling EFIS systems, it can respect bank angle, airspeed, and G limitations too.

If you are seeking a redundant solution, consider this: our products are priced so well that two EFISs, one of which is a two-axis autopilot, start at just $5900 with servos. Compare that to the cost of outfitting your aircraft with just a single set of flight instruments and an autopilot from anyone else. An EFIS-D10A plus two servos is only $3700.

Servos - $750 Each

Dynon Avionics servos are dimensionally identical to other leading servos for drop-in upgradability. Behind the scenes, though, the SV line of servos are all-new. A lightweight aluminum case houses a stainless steel gear train to optimize weight while not sacrificing strength. The servo control arm is captured by a castellated nut and secured by a cotter pin, just like other critical interfaces in your aircraft. Each servo is managed by its own microprocessor, making the servo an active, smart extension of the autopilot. This simplifies the control-surface-to-servo calibration, and prevents the servo from driving itself endlessly like other servos can. As an ultimate mechanical failsafe, a simple and effective shear pin is employed to let you break the servo free of the aircraft control surface in an emergency.

Multiple servos models are available to suit different aircraft control force requirements. The SV32 is rated at 36 in-lb of torque, the SV42 at 55 in-lb, and the SV52 at 72 in lb. Servos are also available with with capstan drives for use in aircraft with cable-driven controls.

Mounting kits for popular aircraft models are being developed on an ongoing basis, with kits for most of Van’s RV series available now.

For aircraft that Dynon has not yet developed a mounting kit, but which definitely use a servo with output arm (as compared to a cable / capstan drive servo), Dynon has developed a generic kit that includes rod ends and other servo attachment hardware. Note that if you use this kit, you will need to determine an adequate location and mounting method for installing your servos.

D10/D100 Series
AP74 Dedicated Autopilot Interface Module - $450

The AP74 Dedicated Autopilot Interface Module adds panel-mounted controls and LED light status indicators to your autopilot. A multi-purpose value knob allows quick adjustment of the BARO setting and the bugs used with the Autopilot. The AP74 adds the abilities to pre-arm which modes will be flown upon autopilot engagement and pre-select the target altitude and heading/track. Additional features include a built-in light level sensor to automatically adjust the screen brightness, and synthetic voice alerts when connected to an auxiliary input on your intercom.
