REFLECTOR: W&B arm for fuel tanks for STD aircraft

[Scott Derrick]

just to be clear my average fuel arm of 123.7 is an average. as I 
remember it ranged from .5 to .9 as I added fuel.

Gross weight, I think its what ever you decide to flight test it to? 
With my io360 I used 2400 as my gross.  I'm raising mine to 2600 after 
my engine and gear upgrade.
