Five toilet rolllllls!
Eight packs of pasta
Seven Nightingale hospitals
I need a team effort here, I would like to produce a Covid related 12 Days of Christmas, to start us off, here are the first four days:
On the first day of Christmas my true love gave to me, a Barnard's Castle eye test for free.
On the second day of Christmas my true love gave to me, two vaccines waiting and a Barnard's Castle eye test for free.
On the third day of Christmas my true love gave to me, three tiers of lockdown, two vaccines waiting and a Barnard's Castle eye test for free.
On the fourth day of lockdown my true love gave to me, four national policies, three tiers of lockdown, two vaccines waiting and a Barnard's Castle eye test for free.
Please feel free to complete the remaining eight days.
|Thread: Prandtl Wing FVT-3|
I liked the look of the edf wing next to their logo, apparently they will be revisiting it in the new year, too busy to make it available at the moment. Also, will probably order an exodus as I have the recommended motor and esc going spare, any excuse 😊

Ok, an update.
Wings almost complete, a few points of difference from the plan. I have added some TE section to the ailerons as I wasn’t happy that the top and bottom sheet join would be robust enough without it. I have also added TE section to the third rib bay for the same reason and to strengthen the root joint. The instructions seem to show the 4 inch LE sheeting extending beyond the main spar at the wingtip but the illustrations in the magazine article shows it cut off at the spar, I decided to follow the illustration and not the plan, the bonus is that the cut off section fills the gap in the sheeting at the root 😊. There are no details regarding the servo fitting so I constructed a box between the ribs with square section balsa to accept the servo holders (from Banggood).
I will not add the top LE sheeting until the wing halves are joined and I will probably add a centre rib to support the sheeting aft of the spar. Regarding the method of joining the wing halves, it appears to rely on a 3/8ths medium hard balsa sheet in the space between the first ribs and the upper and lower spars, a support for the front wing locating dowel and the leading edge joiner. Nothing extends beyond the first rib on each side which makes me a bit nervous, normally used to a ply dihedral brace extending to the second or third rib. I will probably add a ply brace to the trailing edge and reinforce the centre brace by laminating it with some thin ply.

I think this highlights the difference between accuracy and precision.
The ruler is precision made, so if you compare lots of different examples of this ruler they will give you the same measured figure, however they may not be accurate So you could measure a piece of wood that is actually 15.0cms long with several different examples of the same ruler and get exactly the same measurement but that measurement may be 14.8cm, so it's precise, but not accurate.

|Thread: Oily Areas During Model Stripdown|
Assuming that the residues left in the wood are the lubricating oil it would probably be better to use Methanol to remove them, not sure how soluble castor and synthetic oils are in acetone or cellulose thinners.
Has anyone tried using Ronseal wood hardener to strengthen soft balsa after removing as much fuel residue as possible? I believe that it is epoxy based and would probably act as a fuel proofer too.
|Thread: Banggood Delivery Times|
The point I was making was that the delivery for the same item from the CN warehouse has varied from Free, to £55 then £80, struggling to understand why unless they are controlling demand to maximise profit by varying the delivery cost.
Just checked again and delivery is now £81 what the heck is going on?
I ordered some servo mounts/covers from Banggood China and they arrived in just over a week. I also ordered Polaris amphibious plane ( I have the HK Skipper and it's great but a bit small and quick to keep track of so I wanted the larger version). That is taking longer but appears to have been shipped after a couple of weeks. When I ordered it the shipping was free, I looked today and the shipping cost if I ordered now is £55!!!! Glad I didn't wait any longer.

Also, the LE and aileron facings are tapered from root to tip, so these were cut from sheet after careful measurement.
After much cogitation, the build has begun with the wings just in time for lockdown 2.
Many thanks to barryt who sent me details of the wing jig which is one method described to construct the wing, however I opted for the second method which was to pin the sheet TE to the board and build off that.
All rib positions were marked on the TE and sub LE prior to construction, the full ribs were glued to the TE first, then the aileron sub ribs and aileron facings. The sub LE was then glued to the front of the full ribs and the part ribs in front of the aileron were then attached. It appears to be straight!
The only problem I have found so far is that the spar cut outs on rib 1 are in the wrong place, but only a few mm out so easy to fix.
Haven't figured out why the spar slots in rib 3 are a bit bigger than the rest, any suggestion?

I'm Soreen, I didn't mean malt loaf, I meant a good single malt whisky 🥃, however malt loaf is a pleasant non-alcoholic alternative.
I'll swap chocolate biscuits single malt!
Just shows you how badly thought out these instructions are, you can't just close stables, you may be able to not give riding lessons at riding centres but people still have to go there to care for the horses.
|Thread: Get it off your chest.|
HID lamps work by striking a high voltage arc through a noble gas, Xenon is most commonly used, no halogen elements involved.
Quartz halogen lamps heat a tungsten filament to produce light. The tungsten would normally gradually vaporise and deposit on the bulb envelope darkening the bulb and thinning the filament to the point of breaking. However the presence of a halogen, usually Bromine or Iodine and the use of a close fitting quartz envelope means that the deposited Tungsten is hot enough to react with the Halogen and evaporate from the envelope keeping it clear. The Tungsten Halogen compound eventually contacts the hotter filament where it decomposes and deposits the Tungsten back onto the filament. A very neat cycle of chemical reactions.

They are one and the same.
Some people replace their standard headlight bulbs with HID or LED bulbs which are illegal unless fitted in a type approved headlamp because the beam pattern is incorrect and in the case of HID require headlamp washers and self levelling in order to prevent blinding oncoming drivers.
Also, if you have stopped at traffic lights or junctions take your foot off the brake pedal, its just plain ignorant to keep your brake lights on when there are cars behind you.
