Wow, am I missing something?

Got everything assembled today (except wheel pants, not installed yet) and weighed the components to come up with the AUW.

My DigiWeigh was used for the lighter parts because it only weighs items up to 1 kg. A digital postal scale was used for the other stuff, accurate to 0.1 oz.

My AUW (including wheel pants) with the Zippy battery set is 4.868 kg, and with the Rhino set it is 4.904 kg.

I thought I forgot something so I triple checked. It was weighed with the APC 20.5x14 which weighs 123.4 grams, but I have the Falcon CF 20.5x14.5 which weighs 64.6 grams, so I could easily shave another 2.07 ounces. This weight includes the Tech-Aero dual regs and two 800mAh Rx batteries. I chickened out on the 350mAh batteries because they were just so small it was scary. Maybe later.

Very happy camper at this point!

I just hope it balances on CG with the main batteries... I'd hate to have to re-position anything.
