Nose weight too high

Having a university lecturer, economics, with a PhD in the family (there are other PhDs but not teaching), who can’t remember which way to tighten a nut on a bolt (righty tightey, lefty loosey) I am very sensitive to the gulf between academics and practitioners. The two disciplines are more divergent than many academics believe. As a qualified pilot for light aircraft, I was sensibly fussy about who I learned from because of the high cost of failure. Interestingly, the mandatory exam covering weight and balance also took account of the fulcrum provided by the centre of lift, complicated by drag, thrust not to mention gravity. There is most certainly an essential place for theoretical learning. As I’ve said above, some practical grounding helps too. The two lecturers who I found to be easiest to follow had previous experience in industry. One at British Aerospace and the other at Marconi.

CT is in a position to offer members useful advice. A couple of years ago we stopped at a non EHU, rally site, next to the owner of a brand new Lunar, not his first. He was a retired MD of a factory. But when his battery flattened due to a continuously running water pump, he hadn’t an inkling as to why. He didn’t know that pressure sensitive water or microswitched taps were alternatives - lots don’t. An air awning discussion was common following their introduction, with numerous fictions about leaks and wind resistance. We’ve grown through that now, with air awnings becoming commonplace. Wild misconceptions regarding the relative load bearing capacities of A frames, jockey wheels and corner steadies abound. It seems to me that an enquiry from someone who doesn’t know, should be treated with the respect of a knowledgable reply, not a guess from another unknowledgable member.

Such assistance needs to be well grounded in its relevance to the OPs enquiry. Posts telling us “I haven’t got one, but I should think” are far less useful than “we have one and this is our experience”. Ditto creating a desired noseweight by shifting loads doesn’t require a full blown mathematical model when a summary of effects is all the OP needs.

While the above debate might be an amusing diversion, rudeness doesn’t have a place anywhere in civilised disagreement. It’s commonly a sign, along with anger, of a tenuous argument. Upon which thought I hope that all participants enjoy the current heatwave as much as we are in the New Forest - in peace.

A bit like life, better when your up and then you read posts like this and your back down again. I just weigh the nose and move things around till it is what I want. don't need any calculations. as the meercats say, Simples.

you could get 1 safefill bottle, 7.5 k.g. bottle is only  about  11 k.g. full

2 x 6 k.g. Calor bottles will be about  13-15 k.g. empty for 2
