Default Dynon Pitot Heater Module

Just wondering for all those that installed the heated pitot from Dynon in their -9. Where did you mount the heater module? Any photos or advice is greatly appreciated.

Default On a rib accessible through the access panel

-7, not a -9, but the same idea... On a rib accessible through the access panel near the pitot.

Just like this, with the screw heads facing the inspection panel so you can remove it if needed.

On the outboard side of the end rib so it is easily accessible when the wing tip is removed.

Default nutplates

And add some nutplates to the back side while you still can do it easily. They are lighter than a nut and washer and they won't fall off and roll to the most inaccessible place in the wing like a nut and washer will...

And you can remove a screw from a nutplate with a long screwdriver and three fingers, while inventing new vocabulary, in a position where it would be absolutely hopeless to try to get to the backside with a wrench on the nut.

Save yourself maintenance effort during the build process, every chance you get.

Default Dynon pitot heater module

On my 7A I have installed it the same as Airguy except I have run all my earth wires back to the firewall earth block.

I put mine on the access panel itself that is right under the aileron bellcrank. Maintenance doesn't get any easier than that!

Just like Airguy recommended for easy removal should it need repairs. I also added a service loop for the dynamic/AOA feed should the pitot need to be sent in for repairs also. I would share pics but the Expercraft website has been down.

Jereme,
Have you got a photo you could share of what you did? I'm about to close up my left wing so timing of this thread is gold for me, and I was favouring putting the controller onto the access plate for maintenance reasons also. I could still modify the ribs easily enough (with nutplates etc as per others) as the skins aren't yet on my wings.
