|Thread: Is the hobby dying/dead|
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.

She's looking good Dwain!
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.
|Thread: Cox 0.49 Aeromodeller magazine ad from the 70`s|
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.
|Thread: Newbie ish|
Ally, What method of lauching did you have in mind? When I started, the choices were towline, bungee, or a small engine on a power pod. These days an electric motor with a folding propeller or discus-launched are popular methods.

|Thread: Floatplane waterproofing|
RTV just means 'Room Temperature Vulcanizing', i.e. it cures on exposure to atmospheric moisture at room temperature. Therefore bathroom silicone sealant is RTV, although it often has fillers in to reduce the cost and possibly enhance certain properties, so isn't 100% silicone.

Tigerman, Black Horse Models are based in Vietnam.
|Thread: Bowman kit, the Mini Skyman|
Great find Steve! I always fancied a Mini-Skyman but never got round to getting one.
|Thread: First full size electric aircraft flies.|
There are a good number of short hop flights around the world for which the electric Cessna Caravan would already be the best solution. For passenger safety, propellers must be stopped when boarding and disembarking, which drastically shortens the service intervals on turboprops; hence the reason Aurigny in the Channel Islands hung onto their piston-engined Trislanders for so long. Air-cooled piston engines have their own problems with lots of starting and stopping, so on short inter-island routes electric aircraft are already at an advantage. Two or more motors would be desirable though as electric motors, and speed controllers do fail.
The 90 second Westray/Papa Westray route may be the first to be electrified in this country, Loganair were toting this a couple of years ago, and with the help of Cranfield Aerospace are converting one of their Islanders.
|Thread: Old Model for old modeller|
Victor, Just in case you are still looking for Precedent T180/T240, this one came up in East Grinstead on Facebook Marketplace. He says its 8' span so may its a T240, otherwise he's a fisherman and its actually a T180!
|Thread: Gone,but not forgotten kit mfg|
If you had the KeilKraft Handbook in your youth, you probably drooled over their 'Intruder' F3a pattern ship. 72" span for 10cc engines and 'full house' radio... The stuff dreams are made of! That picture in the Handbook was the only sight I had ever had of this mythical beast...

|Thread: Wanted: MFA Yamamoto 1600|
Another New Yamamoto on eBay starting at £5: New Yamamoto in Northampton
If you are into these, it would be worth it for a spare fuselage.
The tailplane looks decidedly small and definitely not the original shape
