I wish to develop a platform for geophysical work. The problem is that suitable geophysical receivers are copper coils with a weight in excess of 5kg - with ancillary electronics the total payload would likely be 10kg.In addition, an air coil receiver would need the largest possible cross sectional area to be carried horizontally, whilst a ferrite core receiver would be a longish (0.6 m) cylinder to be carried vertically.Model airplanes are generally smaller than this, whilst ultralights/para-gliders are considerably larger. Does anyone have any suggestions for a suitable airframe to get started with?

I have considerable experience with TDEM in the field with fixed and rotary wing. In your words: "you are a geophysicist - not an aeronautical engineer," and need a turn key solution that is available and affordable. I would prefer to go offline with you to discuss your needs. You can reach me through my email at thorpe@seeop.com or 480.355.2435 (USA).
I have a platform (AI-extended) that is based on the senior telemaster, it uses a MicroPilot autopilot we have it done numerous test flights and have the flying parameters dialled in for quick use. It could also easily be transferred into the larger telemaster platform if required.
If this is something that interests you please let me know.
kite LTA systems - I hope - will be optinal for the geophysical work. For ex. - as that: http://www.allsopphelikites.com...
Also usual tethered balloons - chip and simple way do your work (see as that: http://dkba.ru - russian aeronautic tech. company [site in russian, use web-translater for it]...)

Try http://www.aerovate.com/ this sUAV should be able to accommodate the payload you are talking about...(as long as its not in the service of Bob and his cronies) ; )
I initially considered a helium blimp, and will likely use one for development of the geophysical receiver system by simply dragging the blimp around by hand on a tether - the slow motion is advantageous for time domain receivers. The problem I see is that the blimp is too large to transport filled with helium and will need to be inflated for each use - deployment in windy conditions may also be a problem.
I then investigated para-glider or powered hang glider type platforms, which are easily transported - but a down scaled model would be required. The final application will require the platform to complete a grid survey unmanned.
