Davtron Inc. recommends that you purchase our products through your local avionics shop and have them do your installation. They know how to handle all the log book entries you need for FAA approval.
Overall appearance is nice, appears well made. Complaints are - 1) the probe is hard wired to the instrument and about 1/2 in diameter, so hopefully you have the room to run the probe where you need it otherwise you will be cutting and splicing the probe wire. 2) The mounting screws are 4-40 which is fine for a new install but if replacing an existing instrument you will be finding yourself retapping the threads in the gauge to 6-32.
