Spent the day working out the final details of the AOA/Pitot mount. The issues were: a) How to connect the 1/4" Tygon tubing to the 3/16 aluminum tubing on the AOA/Pitot tube? b) Once the means of connection is determined, how to route and secure the connection? c) Where to mount the Dynon AOA/Pitot controller? Solved each one of these questions after first doing a little research. I used an old computer power supply to operate the Pitot Heat and determined this Dynon AOA and Heated Pitot with temperature control only gets 120F - 125F degrees at the tip. It gets this hot in just a minute or two and never exceeds that even after an hour of straight operation. Also the base of the unit does an excellent job of localizing the heat and dissipating it quickly. Even after an hour, the 3/16 inch tubing (where it leaves the base) only gained about 5F degrees and remained about 85F degrees (about 80F outside today). As far as serviceability, each tube has a 90 degree bend (to meet up with the service loop of rubber tubing) and extends only 1 and 1/2 inches away from the main portion. This allows for removing the rubber line, disconnecting the wires and pulling the AOA/Pitot mast free through the mounting base. All of this can be done via the access panel in the wing.
