  1. Not wishing to be too pedantic...but the radar is the Type 84 Long Range Air Defence Surveillance radar, designed and built by Marconi s, The 60 ton aerial (designed and built by Vickers) and cabin rotated normally at 4 r.p.m....but could be set to scan a smaller sector. Primarily used to control Coltishall's Lightnings....and those from further afield.....and later Wattisham's Phantoms in amongst other things intercepting the regular 'Bear' incursions ! How do I know? I maintained and operated it for more years than I like to remember! Part of the unknown / unloved / unrecognised R
  2. Very small point soldering iron, finr solder (you can stretch the normal stuff to make it thinner0, and a clamp made of a modified clother peg. 'stip and 'tin' the fine leads first, smallest wipe of solder on the 'lands' of the led, magnifying glass and a quick 'dab' with the iron... and Robert is your mother's brother!
  3. 3014 SMD LED Warm White 120° 2000-3000mcd@20mA 2800-3500K, for the one you have selected means :- 3mm long, 1.4mm wide.............so pretty small LED .............. ...........Light Emitting Diode......but we already knew that! 120° ..........................the angle from which it is visible 2000 - 3000mcd...........the brightness at the stated 20mA current in microcandela 2800 - 3500K ..............is some kind of code for the colour temperature......beyond me! Rex
  4. No problem mate, just use the advised value for the colour LED that you are using.......green are different to reds which are different to blues etc......all reds can be fed by a common resistor, all greens on another etc etc...... fill in the supply box eg 9........and the forward current given in the suppliers specs eg 30, check on the Forward Voltage [?] for the colour you wish to use and add the value given...in this case 3.3 to the box. (this voltage is only necessary so that when the wizard designs your circuit. it can work out for example that if you were going to use in this case

  6. You may find this site useful. http://led.linear1.org/led.wiz I used it extensively when I was building the Hermes model now at Aeroventure Doncaster or this one for single LEDs http://led.linear1.org/1led.wiz Please note that you cannot mix different coloured LEDs on one circuit as they all need different operating currents. With a light bulb, the brilliance depends on the voltage and it doesn't matter which way around you connect it, when the voltage drops, the brilliance decreases until the blub goes out, current is immaterial. With an LED , it doesn't give a monkeys what the DC volt
  7. The white streaks are probably the matting agent, needs a lot more stirring......shaking just wont 'cut it', what to do about it now......not sure..that's another problem!
  8. Can I ask you guys to enlighten me please? How do you get Flightradar to display the aircraft idents as labels without just putting the cursor over them? They only appear on my screen when I overlay a particular aircraft. Thanks Rex Cancel that request! found the answer under tools.....now I feel like one!
  9. Should read Nato IR absorbative Green Out of interest....it appears pink if scratched!
  10. Here' s mine https://www.facebook.com/photo.php?fbid=10153072700248605&set=oa.722938874485494&type=1 Rex
  11. Nice model......had a heck of a job with the etch for the side lift! Well done......looking forward to seeing the rest of the fleet! Rex
  12. Might be worth a look at Airfix Mag Sept 77 if you can get hold of it! Rex
  13. Suggest you assemble parts separate from the model! You don't want things to melt. Keep brass clean, I use liquid flux (Baker's Fluid) and then Carr's Solder paint. Brilliant stuff, basically finely ground solder in a flux solution. Apply where you need the joint, heat metal (mast) with solder iron, wash off the surplus, (great for etched sheet doesn't block the detail as it stays liquid where it is not heated by the metal). You can use a small crocodile clip between sections that you are soldering to act as a heat shunt. Hope this helps Rex PS the solder paint is pricey but will last
