RV-14 Pitot Tube/AOA lines
 
So I'm reading in my plans that if I want I can have a different pitot tube on my wing and AOA as well. I don't know the options for what is available or how to make the adjustments to install different things. What can I read and look at to make an educated decision/purchase?

Most other model builders install the plumbing and mast then decide on pitot/AOA later but if you plan on heated pitot, you also want to look at the placement of the heater controller now or for the future. Brand of avionics may also drive the decision.

I bought a Gretz pitot mast and Garmin heated regulated pitot for my -14A project. I also bought the Safe Air "Dynon tool kit" plumbing kit that contains all of the tubing and fittings you will need.

I moved the Vans supplied Pitot parts to the opposite wing as an unheated independent Pitot for my backup EFIS (small Dynon or GRT mini type). Then I installed a Gretz pitot mast near the proper location. Don't worry about the manufacturer of the pitot tube yet. The Gretz mast fits most of the major brands.

so you bought the following kit:

I assume that it is cheaper to buy as a kit than to buy stuff separately.

I also am at the point where I was making the decision about the pitot. Well actually i stopped thinking about it and purchased a Garmin heated pitot and the gretz mast.

I think that I will take the Tim Olson approach and mount the pitot in the last bay on the wing. I am concerned about having the pitot where Van's suggests, since it is right next to the tie down. http://www.myrv10.com/N104CD/wing/20050206/index.html

I am wondering if I should have a spare pitot. Put in the Vans on one side and the garmin on the other. Maybe this is overkill.

RV14 Pitot
 
To those building an RV14. Vans suggested to me the pitot tube will be included in the avionics kit. Other than installing a mast which is compatible with the avionics kit, it may be less expensive to wait for the avionics kit.

E's RV14 Blog
 
One of the builder sites I read. 'E" does a great job of documenting his build and has a section on the pitot mast and tubing installation...may be worth a look.

Felt like renewing this thread again.

I'm at the step where it is time to make the 7/16 hole for the little aluminum pitot tube. I would like a heated pitot option and the standard install does not provide for that.

If I don't want AOA, can I just get the Gretz mast and run the single line of tubing to that location? I'm not sure how the AOA works but it looks like people have two tubing runs for that? Having never used an AOA I don't know what I'm missing.

What is the least exciting, plain jane way to get a heated pitot going here? All I know about is the Gretz mast and the Garmin heated pitot.

Dudley, if you are not sure about wanting AOA you can just install the Gretz pitot mast and move on. You definitely want a mast mount type pitot instead of the stock hydraulic tubing pitot. The wing altready has extra holes that will allow you to run the AOA sense line later if you want. You can choose the pitot you want later when you start buying avionics.
