R22's come with both Main and Aux tank dipsticks calibrated in USG.
R44's come with a dipstick (for the Main) which give you the total contents of the two tanks combined, calibrated in USG.
Dipsticks, rotor tie-downs, fuselage cover, pilot cushion, cyclic end-cap and fancy documents bag are all standard with a new Robbo. Obviousley over the years things go missing, mainly dipsticks though!
