Looks like urea to me. A lot lighter than super. Hard to overload unless you have a big bucket or hungry sides fitted.
The scales are electric so not affected by atmospheric pressure.
In my experience loader drivers are blissfully unaware of aircraft MAUW. They just put in the load the pilot asks for.

18roll,
Mate are you a pilot or just trolling. In my nearly 30 years flying both semi-rigid, fully articulated and rigid turbines but never having flown an R44, be bit surprised if you can get Ground Resonance in a Robbie, or any semi-rigid system. Hey Ho, every day a schoolday! Matter of fact going spraying next tour in an Astar, quite susceptible to ground resonance, never had ground resonance once in quite a few years, landing on a raised deck and using electronic calibrated equipment to weigh and measure loads. So no effect Also the odd downwind approach and landing when empty and light, again no effect on equipment.

It's the R44s inverted flight tanks which cause the ground resonance and because of its LTS tail construction it is more susceptible to tail wind conditions,this tail cone construction causes an accerated mass flow down through the advancing side of the rotor disc(similar to a convergent duct effect)creating a increase in velocity and decrease in pressure.this phenomenon would effect the surrounding air pressure substantially.The Astar does not suffer from these flight conditions because of its clockwise main rotor rotation.

Just to make sure, in case a studious Googlenaut ever gets directed to these pages, that the polite silence of the PPRUNE community in light of your deliberations, 18roll, must not be interpreted as sign of approval.

18 roll - the machine is nowhere close to the loader/scales when the shot of the weight is shown the loader driver hadnt even caught the bucket so I dont see how that could affect the weight of the load

R44's do not suffer with GR BUT they do suffer from the Robbie Wobble, the tail can get in to a significant "wobble" on start up and shut down, I recently flew a 44 where I thought something had come off it was wobbling so badly.

Off track slightly but still talking about overloaded R44s, I've been looking for a web video of a 44, somewhere in eastern Europe I believe (?) where a rather large gent gets strapped in the front seat of a 44 for a scenic flight.
The machine gets airborne and is immediately and clearly trying to fly with the C of G well forward of where it ought to be. They stagger around in a partially controlled hover taxi for a short time before the pilot plonks it down in a building site straddling a few courses of masonry blocks and no doubt doing some damage.
To top it off, the ground crew come running over to unload the passenger and the pilot gets airborne without so much as a look over the aircraft.
If anyone has a link to that it would be appreciated. Cheers.
