"Onan" did you happen upon anyone working on the Rosie Inverter ( formerly  Little Willie)  or the little sister?

Stopped by yesterday, Saturday. Weather was really nice so not too many MS folks around. I overheard that the final production castings/cases are done for Rose and Lil Rose. Sorry, no pics as they were nowhere to be found. Maybe next visit?

I did come across the 3D printed prototypes though and got a pic of them side by side to show the difference. These all black plastic versions do no justice to what the final machined aluminum ones will look like!

Also took some pics of what I believe are the production run versions of the meters for the B-17, and a quad meter set that "might" be found on an Epanel for the Rose/Lil Rose? Robin will have to verify that. I know the Quad meters will be on some Epanels for sure.

I've been kidding Midnite about putting an MP3 player in the Classics or B-17's. Maybe the "VU" meter is a hint?

The MNGP2 casting has been made, not the other die cast parts. I am waiting to see if all the parts fit. Those electrical engineers keep changing things on me. I suspect all die castings can be ordered within a month or two.
All the tooling for the custom plastic and rubber parts for the MNGP2 are also on order. We spent a lot of time Saturday with three East Coast tech support and sales people going over the menu structure for the MnGP2. We have them here for a week. By the time we were done, I cancelled the label for the MNGP2. We changed it quite a bit.

The VU meter is how we have been getting them. It takes about 1/2 hour to disassemble and rebuild each meter. We put our own lighting circuit board and back lighted meter face in them. There are 5 different meter faces on each B17. I hope to improve that time in the future.
The quad meter is indeed for a pre-wire system. I will include a CAD picture of one here.

Thanks for the update Robin!

Hmmm...maybe a Marine version? :)

Robin,

Can you narrow down the Beta timeline any yet with all the progress that has been made so far? 

Everything looks great, can't wait.

Give me another month and I should be able to nail down dates for the Rosie, B17, Comm box and Barcelona.
