"That depends where you put it, so if you do a weight and balance calculation and remain within the moment limits..."

Assuming you are familiar with weight & balance calculations... the moment limits are defined in the weight & balance part of the RFM imitations. They can change depending on the AUM, but above the max AUM and below the min AUM, there are no moment limits defined !
Also not mentioned earlier on the thread - the undercarriage can also be a limiting factor for AUM. Too heavy, and your gear/skids may collapse if and when required!
