The BC-5R is a multifunction Data Recorder, designed to record data in five categories. The BC-5R is encased in a 3.80″ x 2.64″ x 1.6″ gold-plated enclosure. The BC-5R can be mounted under the instrument panel or in an equipment bay. It comes equipped with a USB cable and data stick for accessing stored data.
The BC-5R incorporates an internal clock that is used to Time Stamp each row of data as it is recorded.
The BC-5R is capable of monitoring up to three Event Lines. These Event Lines are normally used to mark data for flight testing.
The BC-5R monitors and records bus voltage to the instrument.
The first seven channels of the BC-5R are configured to interface with Electronics International’s (E.I.’s) engine/aircraft instruments.
The eighth channel of the BC-5R can be used to monitor GPS data. This is normally Moving Map, Aviation or NMEA data. The data records are Next Waypoint Name, Latitude, Longitude, Ground Speed, Altitude and Track. If this channel is not used to monitor GPS, it can be configured to monitor an additional E.I. instrument.

The Data Recorder is equipped with a multi-color LED designed to display the system’s operational status through various colors.

Excellent customer service. Without a doubt the best aviation part I have purchased.
My interactions with EI were all very positive. When I ordered the Dual CGR 30 instruments I was told there would be about a 6 week delivery time. It took a little less than 4 weeks. I am extremely happy with the service and product.
Excellent Service, superb product.
Your company shares a good reputation!
E.I. Always Exceeds Expectations!
The R-1-6 is a great instrument. [I chose EI because of] quality.
You folks do a great job. Keep up the good work.
This is the third EI instrument I am having installed in “Lillybelle .” I am impressed with the ease of operation, the affordability and the accuracy of each of these instruments. For years I trusted my life to 50+ year old gauges. Now I don’t have to. What a relief!
All looks very nice. [I chose E.I. because of] previous experience.
EI representatives… have been very helpful, truthful, and knowledgeable… We had no idea, that a few weeks later [after our purchase], we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.
I like how the kits ship with everything needed for install and the wire labeling was very helpful.
Awesome product. Fast easy installation.
