AeroPod, PowerPod and Newton

Very happy owner of a brand new AP now, thanks!

Big list of thoughts and questions that are hopefully helpful to others as well.

1) Issac does not default to Profile 4 when I launch it, connect my AP, and select Device/Set Up Device. This is on the installed Issac software that I have used for a few years with my old PP. Which begs the question, should I reinstall Isaac and start clean with AP? The install I have is version 4.1.1

2) On my road bike I have machined a custom aluminum mount for a number of reasons. I wanted the AP a bit lower and centered for aerodynamic reasons. Also, I ride my road bike a lot in a pseudo-aero position. When the AP is mounted in either a bar, stem or front mount, my hands hang in front of the pitot tube. I had this problem with the PP and I'm not sure if I have solved yet. I've attached a few pics to clarify.

Some questions:

1) How stiff is stiff? If I push down on my mount at the AP location pretty hard it deflects maybe a mm at the most.
2) What's a good downward angle for the pitot tube. Mine is -1.4 degrees.
3) Regarding the hanging pseudo-aero hand position. Can you give me some guidelines for what will be problematic. Also could I extend the pitot tube to get out in front of my hands. OK, plenty too much for now. Hopefully I've started some useful thought and discussion.

OK, the post keeps dropping pics. Here are the ones related to hand vs AP pitot tube position.

Well this is frustrating. Now the side view

1) When you launch Isaac, what profile is shown when you go to Device/Setup device? It should be profile 4. If not, manually set it to profile 4.

2) Your "dangling hands" position MAY cause slight changes in CdA readings. It's hard to tell from the photos; a bit of experimentation will reveal the answer. In general, AP needs to see the same pattern of wind.

3) I'm a bit concerned about your mount. If it can bend 1 mm, then it may not be stiff enough. Please do a ride and post the file; I will be able to tell from that.
