For those of you who have installed (or are considering  the installation of) a  12 volt heated Pitot tube in your aircraft, could  you please provide me with an indication of what is being installed/considered  out there.

  

 I am considering either  the Gretz Aero GA-1000 or the Falcon (12-AN5812) Pitot tubes or equivalent and  would appreciate any feedback please.

  

 Has anyone installed and flown their aircraft with an  angle of attack probe, if so which one and your thoughts regarding the device  please.

  

 Regards

It’ll be hard to beat the Gretz for price and performance.  It’s an experimental only pitot, but it’s a “smart” pitot tube.  Other pitots throw raw amperage to the tube, which after a while wastes the energy on heat and can overheat if forgotten in dry, VMC air.  For a very comparable price, the Gretz warms the pitot to about 100 degrees F, and then through a circuit board reduces the energy to maintain the temp at about 100.  There is an LED board to let you know status of the tube at any time, and the instructions are about middle of the road for simplicity.  Of course, I like things spelled out very simply though.  

   

Read more about it on Gretz’s and Tim O’s sites.

Along that same theme....what type of tubing should we (or can we) use 

with the Gretz?

It's in the instructions, not sure if they're available on Gretz's site.

You can use either aluminum or "plastic" tubing, a la SafeAir.  Instructions

say that if you use the plastic-type tubing to use a short run of metal

tubing before changing to the plastic.  I used the 6" metal run built into

the Gretz pitot before I connected the plastic tubing.

From the Gretz Instructions (thanks to those that sent them to me):

To plumb the tubing to the airspeed indicator to the pitot tube, the 

builder can use either the plastic type of instrument tube or aluminum 

tube.  If the aluminum tube is used, not the "additional parts needed" 

list at the top of this sheet.  The builder will need to flair both the 

tube from the pitot and the tube coming from the panel.  Connect these 

together by using the parts listed.



Additional parts needed from another source (for attaching pitot tube to 

aluminum line

1 each AN 815-4D union for flared tubes

2 each AN 818-4D nut

2 each AN 819-4D sleeve



As you would expect builders are using both aluminum tube (as per the 

plans) and plastic tubing.

Patrick,

  

 I started with the Falcon  because of a long track record of reliability, but they did not have a mount  that would work with the RV-10. I returned it and bought the Gretz. Falcon now  has a new mount for the 10 and you may want to consider it. The Gretz has a  really cool temp control function that will save power but I have not heard of  any reliability data on it. Would love to hear from those flying is the Gretz is  working OK in IMC.

I use the Gretz mount for the Falcon pitot.  Works great.  I would also like to hear how the Gretz pitot is working out for people.

I don't know what criteria would be ultra valuable regarding the

pitot tube, but the indicated airspeed is good and close, there's

no worry about rust with the Gretz, and I've been in soggy IMC

at 0 degrees C, and not had it ice up.   The thing is, until

someone actually has a problem with it, I wouldn't expect anything

but ordinary "it works fine" reports.  Before completion I had

worried that perhaps some day I may regret my choice.  At 177

hours, I don't have any regrets, for what it's worth.

Thanks Tim and Jesse, looks like the Gretz is the go.
