Fairey Firefly MK5 from Vance Mosher plan

Interesting, they're to V11, I think, but to my mind V9 is the best. Be very careful, it appears you can't save what's on your chip, if you don't like an iteration it's difficult to go back, it's gone.

Well I stuffed that up! My CNC router came with V0.7, I found V0.9 to be better, I was lucky I bought 5 of these

when they were still pennies and the postage was free!
I was able to upload different version to each one and select the one that I felt was best. None of them are perfect but all my machines are 64bit so that might be contributory.
In the 80's I wrote Machine Code programs for Z80 based machines, hence the interest.

Jindivic - popular target aircraft for surface-air or air-air gunnery.
If you had read my book Sea Story, or even one of the Vince series, they get mentioned!
There were various models, some powered by a piston/prop, and a later model- by a small (by those standards!) turbine. Usually catapult with jato launched (no runway on a frigate or RFA!) 'Landing' at sea was via deployable parachute, and 'rescued' by a small boat.
The radio in the versions we used was manufactured by Radio Control Specialists (RCS) of Hounslow - they also made (crappy!) hobby r/c gear using rubbery plastic Orbit servos. You could fit modern r/c gear including the servo's - into the rx case! Powered by a four cell 500 mah nicad.
Crappy - I had one. Big heavy steel box, with a big - I think PP6 9v - battery in it, good for about an hour of use, (later changed to a nicad) and a half-wave telescopic aerial. The (very slow) servos were five-wire, as discussed elsewhere, and almost centred, the electrical centre varied depending on the temperature and mood of the servo at the time!

Jindivik was developed during the late 1940s and into the, early 1950s by Australia's Government Aircraft Factories (GAP) in response to a need by the RAF and RAAF for a cost effective, high performance target drone. One unusual aspect of development was that two manned examples, known as the Pika, ( and subject of a High Planes kit) were constructed and used for development work, with the first flight in October 1950.

To fulfill different missions, Jindiviks are able to be configured with many different equipment pods on the wings and fuselage, and several extended span wings can also be used depending on the altitude capability required during the mission Initial production Jindiviks Mk Is were very similar to the Pika (with the exception of the nose and cockpit area) but later variants from the Mk 2 onwards were fitted with more powerful Viper engines and incorporated many other changes, including the replacement of what must be the largest ever flush NACA type intake fitted to an aircraft with a more conventional open fronted type.

Jindivik is flown by a ground controller via radio control, take off being effected from a trolley, and landing being performed on a retractable skid in the belly. Typical missions for Jindivik include targets for fighter aircraft and ship defences, as well as radar targets for ground operators. When live firings take place, the intention is never to hit the Jindivik itself, but rather to aim for towed targets or achieve a near-miss with a missile, with the onboard equipment noting the miss distances for subsequent analysis.

Jindiviks are still operated by the RAF/RAE and the Royal Australian Navy, past operators including the RAAF/Weapons Research Establishment, Swedish Air Force with eight Mk 2 operated from 1959 till 1964, and the US Navy which operated 42 examples of the Mk 303 A from Pt Mugu during 1962. Over 500 examples had been produced by the time production ceased. This kit represents the Mk 3 or Mk 4 version with the Mk 8/9 pods.
