[ARC5] A pair of questions

[Bob kb8tq]

Hi

If you are going to try to power essentially an entire airplane, you need to think pretty big
in terms of supplies. It’s a good bet that there *were* disconnects on the real plane for 
the various electrical bits and pieces. It’s not clear to me that they were intended for anything 
other than occasional use (as opposed to part of the normal startup procedure). 

Do you have (or can you get) a 240V circuit into the area the plane demo will be in?

I'm not brave enough to light the entire system up with a single switch....Now, the airplane may end up being different. I don't see any avionics switches on the callout that I have handy. I'll have to dig out the drawings for the power panels, as someone robbed the covers with all the switches long before I got the project.

I'll run over to my local Fastenal and get them to give me an estimate on putting it on one of their trucks.  One of the guys on another board, had some stuff palletized and it was about 75$ to send it across a couple of states on a Fastenal truck. Wasn't real fast...something on the order of a week, but got there fine. They do it space available and store to store only.
