The Electronic Flap Actuator (2071/2072) is an electronic module designed to automatically control an electrical flap actuator and provide visual readout of 3 or 4 flap positions. The device can be used with any electrical actuator providing the operating current is less than 8 amps at 12 volts. A 5K or 10K resistive sensor is required to provide a voltage readout of the actuator position. The control unit incorporates push button switches with built in LED lights. The system can be easily calibrated to your flap system. This involves first placing the actuator in the manual mode then manually moving the flaps to a desired position by pushing one of the switches. Once the flaps are positioned correctly, a combination of switch actions will record that flap position in the onboard memory in the actuator. This process is repeated until the values for all four positions have been stored in the memory.

Once calibrated, pushing any of the switches will activate the actuator and drive the flaps to the correct pre-defined position. When the flaps are at the correct position, the actuator will stop, and the LED in the correct switch will illuminate indicating that the flaps are in the correct position.

The LED lights in the display can be dimmed by hooking the dimmer output to an external dimming voltage. The Flap actuator also incorporates an electrical flap position interface for use with the Aircraft Components P/N 2070 Gear Position Warning System eliminating the need to install the external flap switch.

Note: This system is not FAA approved. It is intended for installation in Experimental category aircraft only.

The Electronic Flap Actuator is available with 3 flap position switches (full up, takeoff position, and full down) or 4 flap position switches (full up, 20 degrees, 40 degrees, and full down).

I installed this flap controller in my Lancair 360, works very nicely. I also installed a speed sensor that prevents accidental actuation the flap control above 125 kts, unlike someone else describes it above, easy fix of that problem. The manufacturer is, however, not something I would recommend to be used or ordered from. I contacted them several times, they did not answer, ever. I even doubt that they are a real company. Hence only the 4 stars.

I did the same thing Erno did. I put a speed sensor in line with the power supply which is set for 120 knots on my Lancair 360. Now it works great. No accidental activations. Being able to program the flap angles is a real plus - you can customize to your flying techniques.

The push buttons are micro switches and only require a slight tap to accuate. I recomend placing this control unit where you will not accidentially touch the push buttons. Yesterday I accidentally tapped button #2 while traveling at 170 knots which put the plane into a nose dive and tripped the breaker. I recommend a redesign with real push buttons. Until then, this is a dangerous product.

Q: Do you have any wiring diagrams available for these Electronic Flap Actuator / Indicators?

Yes, we have added the Installation and User Manuals for both models to the "Documents" tab of the web page.

Q: For the experimental market you'll need to show some dimensional information so we can understand where it will fit in the cockpit.

The dimensions and wiring diagrams can be found under the documents tab.
