GRT Mini

[lrgabriel]

Katie -

Thanks for looking into this, and for the amazingly rapid answer. You guys rock!

I'll get some data back to this thread after I can get a scope on the bus and put it through a few engine starts...just to be sure nothing overly sinister is reaching the Mini. I'm not expecting a huge voltage drop (due to having double the normal battery capacity during start), and I'm using high quality, diode-protected contactors...so we'll see.

Anyway, thanks again.

Any others get their mini X yet ? I know I'm close but it's harder to wait at the end.

This question will vary a lot DOE but how long are you guys taking to install this thing ?

It can be done in a day or less than an hour ... depends.

If you want to get it done the fastest, consider checking to see of you can get the harness for the magnetometer early. Then run that wiring and make the mounting mechanism for the box. The box is the same "standard little box" that GRT uses for a lot of stuff, BUT the connector on the Mini Mag is different (reverse sex of the standard magnetometer.)
<<This work is the largest time consumer.>>

Then if your plane is not flying already cut the hole in the panel and mount #4 (yes number FOUR) plate nuts. Suggest hex head socket screws.
<<This is probably second longest, unless you get someone like Stein to cut your panel in advance. :-) >>

If you don't have any and need them in a pinch, ACE Hardware probably has some (black anodized).

Make available power and ground wires for connection when device received.
<<Probably already available.>>

Make available a "T" for Pitot and Static.

If/when the above is done, it can easily be done in about 30 minutes.

If not, it *can* take a day. Interruptions, breaks for lunch, head scratching, putting plane back together etc. :-)

Interdisplay, autopilot etc connections and setup will add to the time.

It would be most helpful if those who have successfully sourced the necessary #4 nutplates to share their sources and part numbers. When I tried Spruce the only ones they had were p/n 04-02028 (F2000-4) floating anchor nut. These are too big for the job as the floating base of the nutplate is too large. I've since fabricated my own fasteners thanks to having a 4-40 tap on hand.

I just picked up some myself from another source of hard to find hardware: B & B Aircraft Supplies. 33 cents a pop.

These guys are always at Oshkosh in the Fly Market outside vendor area. Great booth to visit to pick up some interesting parts!

I ordered mine, a Mini X, at S&F. It has not arrived yet but I have already installed the wiring harnesses for the unit and the magnetometer as well as the GPS. The mounting hole is cut and covered with a blank so installation will be less than an hour when I get it. It is going on the right side of my panel to augment the dual HX's in my flying RV7A so I have something to look at when my wife is PIC. To bad it is not here yet since we leave for a one month flying trip this weekend!

Regarding the Mini X, is there any difference in the current draw when connected to the magnetometer vs not using the magnetometer?

Thanks in advance.

Yes, but it's tiny. The current draw from the magnetometer is around 50 milliamps, so it's not an appreciable difference.

I wonder, what are chances that a version of Mini would ever be certified under TSO C145/146 or C196? Combined with Trig TT22, which is certified under C166b, this would create a somewhat inexpensive ADS-B solution (under $3800 total). As I understand the situation, Mini already uses a 5Hz WAAS GPS, so precision requirements are met. It only needs to satisfy reliability requirements.
