Unfortunately it's not that easy. Jet fuel is supposed to be for 'aviation use only' and will usually only be dispensed into aircraft fuel tanks (saying that model aircraft is 'aviation use' doesn't seem to wash). Some places allow you to sign a disclaimer if you take fuel away whereas others (BP) will simply refuse to sell it. BP also refuse to sell it on security grounds as some idiot bought some, poured it onto an airliner and set fire to it. Neither Inverness or Aberdeen airport will sell Jet A-1.


With regard to cost, a Wren 44 will burn 1 litre per flight which I don't think is that expensive. Bigger engines obviously burn more fuel but I personally think the running costs are worth it. I have to drive a couple of hours each way to get more fuel but I coincide it with a shopping trip or visit to another flying site and buy enough to keep me going for a few weeks.
