  1. Paints for WWII USN Ships

    Mr. Color Leveling Thinner
  2. Paints for WWII USN Ships

    I believe they were discontinued and then the line was restarted in its current format. They work very well. I haven't compared the colors to Model Master's but the Colourcoats I've used have sprayed better and covered better than the other Model Master colors I've used.

    White Ensign Colourcoats is another option. They spray really well. https://www.hbhobbies.com/collections/us-navy
  4. Missile Lock...

    Our AIM-9s also had a scan feature provided by the SEAM system. (Sidewinder Expanded Acquisition Mode) It would make the seeker head scan in a figure eight pattern until it sensed something, then it would lock on. By using VTAS (Visual Target Acquisition System) the seeker head could be slaved to either the radar antenna or the pilot's line of sight. This was in the mid '70s on F-4Ns. AIM-7s don't lock on to the target, but they do need to be tuned to the aircraft radar's frequency mixed with the Doppler shift of the radar's locked target. Otherwise the missile's receiver won't see the reflected RF energy from the target. The missile is pre-programmed by the radar set's target intercept computer with the correct frequency and with the initial direction to the target. When it is ejected from the aircraft it rolls to orient the missile to an X configuration of the wings and fins from the + configuration that it is carried in. The missiles nose antenna pointed at the target and away it goes. The way it works is there's an antenna in the nose of the missile that sees the shifted frequency and an antenna in the tail that sees the transmitted frequency and by comparing them it knows closing velocity and can calculate its path for a lead pursuit intercept. The tail antenna is fixed as it's receiving the strong transmitted energy from the aircraft, not the weak reflected return and is only using it for the frequency shift and I think range information that encoded into the RF guidance beam. That's why semi-active is better than a beam rider, it can lead the target while a beam rider has to do a tail chase intercept that eats up range. The search and track radar is a pulse system, the missile guidance radar is continuous wave (CW). That's how a target's RWR can know whether it's being pinged, locked on to or actually has a missile guidance radar illuminating it. It wouldn't be able to tell if there was actually a missile on the way though. Back when I worked on this stuff, I don't believe there was any way to know if a heat seeker was targeting you other than seeing the motor's smoke.
  5. Chinese aircraft carrier elevator...

    I find it interesting that they use that dark red orange and black deck edge marking. Is that just to avoid using the decadent west's yellow and black? Do PLAN carriers use red lighting during night ops? Do dark red orange and black deck edge markings turn into black and black deck edge markings under red light?

    I'm betting that line on the deck perpendicular to the aircraft is the "your nose wheel must be behind this line to avoid smashing your radome" line.
  7. F-35 news roundup

    "Two experts", more like one expert and one guy who used to add up numbers on spread sheets a long time ago.
  8. Cockpit parts all painted, now it's time to glue it all together. I'm not worried about the crookedness of the painted-on instruments, they look fine through the fishbowl canopy.
  9. Another IMGUR Question - Resizing

    Choose "edit image", then "Crop/Resize" and then click on the actual number of pixels for height or width and edit the number. If lock proportions is checked it will automatically adjust the other value
  10. Fiddly stuff is mostly done. I added lead foil belts with buckles made out of some bits of 1/700 ship railing photo etch. Also added arm rests and the rail on the back and some ejection handles made out of wire. Made throttles and control sticks from styrene rod suitably chopped up and shaped and added consoles and rudder pedals out of styrene sheet. Boxed in the wheel well walls, the actual wheel well detail will have to wait until the wings are glued together and that has to wait until the interior is painted and installed. For scale, the grid on the cutting mat is 1/2 inch squares (12.7mm).
  11. Best method to replicate anti-skid areas on 1/48 jets

    It's not that rough in real life. Roughness would manifest as drag in flight. Flat paint would be accurate in 1/48, especially if you used a satin or semi-gloss for the rest of the airframe. Ns were pretty glossy up until they went to TPS in the late '80s. They were painted with DuPont Imron epoxy paint which held its gloss very well. I use a 50/50 mix of gloss and flat to varnish aircraft from that era.
  12. some RF-4B help please....

    I stand corrected. I did a GIS and found that plus the black RF tail with three white bars and a special scheme on BuNo157346 that had a red tail and a red "film strip" painted on the spine.
  13. F-35 news roundup

    An F-35 can pick a target for, and then guide a Standard missile launched from a destroyer to that target.
  14. F-35 news roundup

    I know, right? It's missed EVERY TIME they've used it! 100% failure rate against live targets!!!
  15. Hasegawa T-33 with Leading Edge "Silver Shark" scheme from VU-32 out of CFB Greenwood, Nova Scotia in 1992. I saw a warbird in these markings at Hamilton a few years ago and had to do it. It's an OOOOOOLD Hasegawa kit with poor detail. I'll be redoing the wheel wells and putting some belts on the seats but that's about it. Even considering my past group build history, I should be able to finish this by the end of the year, we'll see what happens then. I do have a bunch more in the stash. Note, for all the Photo Bucket haters out there, this was posted on FaceBook to see how it works as an alternative. I'm not spending $400/year to post photos, that's for damned sure. I posted it as viewable by "me only", right clicked the image, clicked "properties" and copied the URL to post it here. HTH.
