|Thread: DB Sopwith Pup flying weight|
I shall do a lot more double checking of weight and balance position, I also was concerned about the rigging attachments, I have crimped a loop behind the gripper (I think as per the plan, too cold to go and check at the mo!) to prevent complete withdrawal of the cable. I still think the tail is over engineered in respect of the amount of wood and corresponding amount of glue required to assemble it so will probably, after double/triple checking my measurements etc, still replace it with a lighter version
a lot Jon!, I was aware of the weight shown by DB but wondered, if like a lot of these things, there was leeway. I shall make the new tail feathers and see what savings can be made, I think the original is quite over engineered considering there is bracing as per the full size, will try using carbon fibre spars and laminated outlines to reduce the woodwork currently employed, I have added a bit of detail (stitching etc) and painted it but didn't think I'd gone overboard with it
my DB 1/4 scale Pup is ready to fly, I've checked the balance point using a vanessa rig and also using scales and calculation and both agree the same position, my concern is that to achieve this required an inordinate amount of lead to bring the point to within 1/2" of the recommended point, meaning the total weight is 24lb, I'm not happy at all with that but wondered if I'm being overly concerned. I do intend to possibly redo the tail plane and fin building it with a lot lighter more scale like structure which will in turn reduce the nose weight needed, but, as I say, am I being too cautious?
|Thread: Dereck Woodward Bigga Bit|
Sure was, tempted to make another one now!
A good few years ago I enlarged this up to 60” span and flew it with an O.S.40fp, flew superbly till I buried it into the grass flying inverted low and fast (up is down and down is up!!), even had a photo of me and it in the hallowed pages of the RCM&E. Such a simple airframe, just make sure the c of g is in the right place

|Thread: Belair Fokker DV11 38" span.|
Solartex will be too heavy on a model this size, there are lighter options depending on what colour scheme you plan on using, laminating film is popular but will need painting (lightly) it’s cheap as chips (relatively) and easy to use, use a Matt finish film, there are various ‘how to’s’ online for using it, or Litespan which is still available from Solarfilm, there are others but these are ones I’ve used
|Thread: Foam Wing Cutter|
the flat wire they do could be good for rigging wires for smaller scale WW1 modellers
Available here Wire

I, like Bob, use cellotape, cheap stuff, nothing sticks to it at all

I thought I was the only one who got stung by the ‘gentleman’ from Staffordshire!
|Thread: Thank You SLEC great service!|
I shall have to look out for that next time I visit SLEC Martin!
|Thread: Forum members' new models: Let's see them.|
My latest build, a Sunbird 1.6 metre wingspan electric glider from a ‘cheap’ laser cut kit, an ‘interesting’ build!, there is now a version 2 of it that seems to have removed the really bad bits of the design (think I got it on eBay), flew it today in a bit of a breeze, really nice to fly
|Thread: Hangar One|
I have the Fokker DVII kit (parts only) ordered it as usual online, delivered to U.K. got it last month no problem, there is import tax to pay (I’ll have to check how much it was) but the kit is excellent and, I think, worth the money. The website is excellent, shows the plans and wood list for each model so you can plan ahead, have yet to start it tho, so the design side of it is to be proven.
|Thread: Idea for Control hinges for small scale electric|
I thought I’d share my idea (no doubt not new!) for hinging control surfaces on small scale electric models. This is the rudder on my Peter Rake Nieuport IV Swallow tail, I’ve done the elevators using the same method, the rudder is small and delicate and I wanted it to look ‘right’, I used short sections of fishing trace, the same stuff I used for the closed loop controls, and used a pin to make a hole in the rudder and stern post, inserted the short lengths of fishing trace and fixed in position with cyano, works a treat and is strong and no binding. Should be able to be used on all controls on small models where the surfaces are too thin for other conventional hinges.

|Thread: Laser Engines - Technical questions|
Hi Paul, if you are making some and you are willing then put me down for one for the 150 please
Hi Jon, is it possible to get the type of sleeved nut supplied with the 180 (M10 thread) for the 150 which I think is a M8 thread?
