Both noted for future reference.

My next project is a multi-function timer for use in electric-powered
scale or competition free flight model aircraft. This doesn't fall in the
GHz category since its based on a PICAXE-14M2 chip on a small PCB, which
is primarily there as a place to mount connectors. Current plans are to
use a Pi2 with touch screen as its control box, which is connected to the
timer to adjust servo settings and delay times.

It should also get me up to speed with using kicad to design the PCB.

Excellent point.

I did a only small amount of RC, back in the days of single channel
radios and bang-bang escapements before discovering the joys of
competition free flight models: designing, building and competing are all
equally enjoyable aspects of that game. I learnt to fly full-size gliders
in 2000 and haven't looked back: there's nothing quite like the sheer
rush of a winch launch followed, on a good day, by a 200-300km cross
country flight.

... and there's a move toward fitting any drone weighing over 750g or so
with some form of electronic conspicuity device.

This is unsurprising, since there have already been collisions with
manned aircraft and penetration of airspace around airfields is far too
common. IMO just how heavy the coming regulation will be depends entirely
on how well the drone flying community can control their idiots, i.e.
convince them that they will only fly outside controlled airspace and
below 120m in class G (uncontrolled) airspace.
