Hello Brian,
Thanks for posting the pictures.
Please answer a couple of questions for me.

1) I noticed the nice little dual pressure gauges. Did you purchase them in the UK, if so where ?

2) Also, you seem to have 2 Rx switch harnesses. Do you run dual 5 cell Rx packs and a battery backer (glorified common cathode diodes) or do you just stuff 2, 4 cell packs directly into the Rx ?

Thanks.

Jules.
