I bought one of those batteries everyone here recommends and it works just fine. $20 on Amazon. I should have bought two of them as sometimes the one almost runs out after 3-4 hours of flying.

My challenge was keeping the Stratux and battery together in flight while getting bounced around.

I added some Velcro to both the battery and Stratux and now they are much more stable.

I also have another piece of Velcro on the "dash" to hold it all down.  This becomes important if you want to use the AHRS function for synthetic vision and want all three axis working on the synthetic display - pitch, yaw and roll, otherwise the device bounces around adn it really throws off the roll and pitch indications quite a bit.  No big deal, but can be distracting at times if it is not secured well.

My 2 cents.

Michael,  you might find you will need to stiffen your glareshield, and to fashion two strips of aluminum bolted to the glareshield over the Stratux.  That is what I did to the 340's glareshield and now the ADAHR is rock steady even in light turbulence. Velcro didn't do the trick for me.

Excellent suggestion Dick! I will see about doing just that...

You must fly in some wicked turbulence out west in the REAL mountains !

Geez, if it is THAT bumpy, maybe I am picking the wrong day to fly for my $100 Crab Cake around here!

As I got/get older, I am less apt to fly on days where I might encounter that sort of turbulence, especially in my humble stock Cessna 150.

Tried flying in the LOW mountains around here one time a few years ago in "light" turb and almost landed the plane on a open field or road as I was getting tossed around so bad.  Lesson to self: flying the C-150 in ANY turb is not anything like the HERK I was used to flying...so I don't do it anymore - once was too much.

Still, I like your idea of BOLTING DOWN the system to keep the AHRS level through the flight. Thanks!

Michael, with the light wing loading of a 150, even very light bumps will move the ADHAR and SV around.  I assume you are instrument rated and might occasionally shoot approaches in the 150.  In that case you will want it rock steady. I riveted two small 90 degree stringers 10 inches long under the glareshield to stiffen it.  I find I have to keep the props in sync or I get a little jiggle in the ADHAR and SV. You probably flew the Hercs before the J model so you never saw any of this high tech stuff before.  B-727s and 720s were my previous rides and all they had were two VORs and one ADF.

Thanks Dick, this makes perfect sense!

Indeed, it's a bumpy ride in the tiny 150 on gusty days...your mounting idea is very good.

I was on H models and then the AC-130H Gunships, mostly.

You flew some great aircraft and I bet flying those NDB approaches had to drive you nuts -- compared to what we have now it is just amazing.  Ha Ha, crossing VOR radials to find fixes, VOR-A approaches, arcing approaches, dialing up the ADF....all things of the past and frankly, good riddance!

I welcome the digital age with open arms!
