Peter, Your father was clearly a courageous man. I guess if he had had a gun jam in combat, having two guns must have given him more reassurance, protection and opportunities. From what Wikipedia says, it took considerable strength to move and operate two guns on a Scarff ring, which is why they reverted to a single gun again after the war.
Peter, Was your father William Miller, flying with George Darvill in a DH4? I only ask because I found this:
Its surprising how effective the two seaters were against the single seaters in the First World War. Presumably why the RAF thought the Defiant was worth getting in WWII.
Why oh why does he say it was modelled on an Albatros DIII? THe Albatros has an inline engine with a big spinner, a fairly rounded fuselage and wingtips swept the other way.

|Thread: Is the hobby dying/dead|
For clubs to survive, its vital that a club represents all its members. A limit on the number of years that someone can be on the committee, and having committee members from those still under training and all disciplines flown, help to keep things fresh. Its very easy for cliques to form, particularly if separate sites are required for gliders and power, and these are often the death knell for a club.

There are only two sorts of weather; building and flying. :-D

|Thread: Matching an engine to an airframe.|
David, The Outerzone plan shows a K&B Torpedo .35 two stroke engine. That is from the days before Schneurle porting which greatly increased two stroke performance. Your SC52FS should be more than match for it. Having said that, I would expect most fliers these days to put a .70 four stroke in a model that size (72" span, although it would not represent the original in flight, except on low throttle settings.
If you are scaling to suit your engine and thinking in current day performance, around 63" would be about right.

|Thread: Prostate Cancer|
Largely on account of reading this thread and a having displayed a few of the usual symptoms, I went for a check up. Fortunately all clear on the PSA front. It's easy to be complacent until its too late though, so I would encourage everyone on here to get tested.

Gangster, the strange thing now is that despite, as you say, less shops stocking kits, you probably see more signs of model flying in parks than we did then. Sure a lot will be drones, but not all.
Well said Barrie!
Model flying is and always has been a new and applied technology based hobby, so as with technology anywhere, it is continually evolving. First Person Video and drones are probably the main things that attract newcomers, and particularly youngsters, into the hobby. Like a lot of us, they will chop and change their focus once they are 'in'.
The rise of electric flight has also meant that a club is not essential for flying smaller models. A sports field, park or farmer's field will often suffice. Simulators mean that there is a fighting chance that some of these flights may even be successful. If not, the EPP construction is at least rather more forgiving than stick and tissue.
The other factor is that new entrants to the hoby are not necessarily youngsters. Pressures of careers,family and finances often mean that people are starting in their 50s or even older. Back in the mid-1990s I taught an adult education class, building and flying R/C models. I was in my late 20s at the time, and the second youngest one there. The bulk of the pupils were in their 40s to 60s with a few in their 70s and 80s.

Dwain, I'll be following this with interest, as its one on my 'roundtuit' list.
|Thread: la.40 in an Acrowot artf?|
Simon, As buying new glow engines means you are finishing in a small and ever diminishing pond, how about seeing if someone has a useable one they would loan or sell on approval? If you are in a club, try asking around to see if anyone has an engine they don't use anymore. If you were happy with the performance of the 65LA, then most ballraced .50 to .60 size engines should be a comparable replacement.

|Thread: What is this model?|
Bob beat me to it. Its definitely Laser 200, Slick 360 or Stephens Akro-ish.
|Thread: Gone,but not forgotten kit mfg|
Whilst people with memories of the models and manufacturers are still around, it would be really good if a database of British R/C models and manufacturers over the years could be compiled. It would be great if we could capture some history on the people behind the models as well as the development and manufacture of the aircraft themselves.
Clearly this would be a lot of work, and it would be ideal if it could be in a format in which anyone could add to it, with a moderator checking submissions. Is there any such software that would allow this? I'm aware of Outerzone, whcih is really good, but something more like http://wiki.rc-network.de.
|Thread: Diesel vs glow on a .5cc engine|
Piers, The lingering smell is most likely to be from the paraffin or castor from unburnt fuel. Ether will evaporate away pretty rapidly.
I would second Peter Jenkins and recommend a Mills .75, of which ever type (original, Indian, Irvine, Boddo, etc). Power can be reduced if necessary by turning a larger prop, which will have the added benefit of reducing the already limited noise still further.

|Thread: Control linkages|
I agree with you. A screw crushing a piece of unidirectional carbonfibre rod is asking for it to crush and break up, leading to a loss of control authority. Epoxying on a snake end or binding a piece of steel rod (softer than piano wire would be desirable) on to the end of the carbon rod would be a better approach.

Although there was a Cox style tank available as a spare for the DC Wasp, they later produced the DC Bee with the tank supplied, and the beam mountings removed.
