I continued the installation of the Dynon Avionics heated agle of attack pitot. This has necessitated a number of changes to the original installation in the aircraft. I now have the basic wiring completed and tested. I think i will have to change out the circuit breaker for this unit, but I will check this first. Final installation awaits a few ordered parts. The initial test shows it gets good and hot.The controller unit is mounted where the 4 screws show behind the access panel.
