  1. @Wez, I totally agree, without avionics and systems any military aircraft is totally useless. The airframe's job is to transport a system (whether that system is a winch, sonar, radar, camera, missile or bomb). Too many people play top trumps, when comparing aircraft, with speeds or g-limits and totally miss the system capability.
  2. @Wez no need to apologise, I do rather like all the avionic chat as it's really not my area of expertise. I chose the design and aerodynamics pathway of my degree, so I didn't go into avionics and systems in depth. I'm having to learn an awful lot about avionics and systems now I'm engineer/aircrew in military aircraft! I understand how to use avionics to do flying stuff however, my view of avionics and systems is as follows: 1. Aircrew input, 2. Black magic, 3. Electromagnetic wave output, 4. More black magic, 5. Lights on screens for aircrew. On the aircraft I work on, though a doppler sensor is still present, it's not the primary source for information. GPS and INS have got so much better now that they are replacing older sensors.
  3. Well this has turned into a nerdy navigation systems discussion - I love this stuff!
  4. Hi all, I've always wondered what the sensor is that is often found beneath the nose of military aircraft. See below, just behind the black nose cone is a sandy coloured square (that appears split into two parts). Tonka (although the F3 doesn't have the same sensor) Here it is on a HP Jetstream And again on a Sea Harrier FRS1 (interestingly the FA2 doesn't have one) It's obviously something to do with the ground and it appears much too large for a radio altimeter. I can only assume that it is a doppler velocity sensor for gauging ground velocity (hence the F3 wouldn't have one, although I would have thought the FA2 would for hovering - unless it uses an inertial sensor). Can anyone confirm what this system is? Cheers Ben
  5. What a superb finish and you are quite right, it is a handsome aircraft.
  6. Very different, clearly some excellent modelling skills needed to scratch build in such detail.
  7. Haha, I'm not sure even a Napier Sabre was enough to overcome the drag from a Swordfish!
  8. Great job, well posed, catches the superb powerful lines of the XIV!
  9. @The Spadgent well this is one to be proud of! Superb job on a lovely kit that still holds it's own, despite it's age
  10. Hi Warren, I have a new 3d printer and I am still in the process of creating all the new print files for the IIIF. It's slow progress, but I'll update this thread when it's done!
  11. Straight from social media https://www.facebook.com/groups/848474938507986/permalink/4694038133951628/
  12. Hi all, spotted this on Facebook, Sywell Aviation Museum are auctioning a 1/24 Hertiage models Lancaster on their Facebook page. https://www.facebook.com/205252919603570/posts/4013140875481403/ It must be an incredibly rare kit and it's for an aviaiton museum - you'll need a lot of space and deep pockets though!

  13. I think this is about it, the AH1 and HMA2 are (currently) very, very similar. They may begin to differ in the future as each operator requests certain specific capabilities. The HMA2 aircraft are currently undergoing retrofitting for FASGW (martlet and sea venom), however this has no noticeable external change (if I recall correctly). Just be aware, there is no suitable donor for making an AW159 in any scale. The only commonality between the Lynx HMA8 and AW159 HMA2 are the main rotors (including head and mast), the forward gearbox fairing, above the cockpit, and the windscreens. EDIT: the sliding doors might be the same too. Ben
