So after fiddling with BG servos a bit more, I decided to give my F-14 some more love and completely visually revamp it. I managed to greatly reduce wing flopping as a result of G-forces overpowering the small servos, so this should be a bit more enjoyable to fly.

Grumman F-14 Tomcat - America's Favorite Fighter A few months ago, for the Jet-of-the-Day thread, I made a functional, visually accurate F-14 Tomcat. However, going back to it, I found it much less accurate than I thought, so I decided to return. At the cost of doubling the part count, I finally have a Tomcat that I'm happy with. The Mechanisms In addition to the visual overhaul, I redid the hinge mechanism to work smoother and explode less. The result is a mechanism that works smoothly in level flight, and is actuated by only two action groups (one forward, one back). The mechanism is pretty interesting. The solar panels in the hinge hold two RCS balls each, in two chambers. The docking ports (facing up) are actuated by the airbrakes between docking ports (facing down). The result is a smooth hinge that's timewarp resistant. The Arsenal The F-14 was an extremely versatile big fighter. It was extremely maneuverable when armed with AIM-9 Sidewinders, and could kill from long range with AIM-54 Phoenix. Long-range interceptor roles used a combination of the two, and this replication follows the most common loadout for that role. On the central pylons are four AIM-54 Phoenix. Like its real-life counterpart, this AIM-54 is a long-range air-to-air missile capable of destroying bombers in one shot. Decouple the missile and use target hold to home in. Earlier versions of this missile were capable of killing planes from kilometers away (in KSP, IRL it had much more range). To complement the jet rockets, there are a pair of unguided missile types. The inner wing pylon holds AIM-7 Sparrow missiles, and the outer one holds AIM-9 Sidewinders. To extend the range, there are a pair of drop tanks as well. More Information In addition to the accurate weapons loadout, I spent a lot of time making sure that the craft would look and function the same as an actual F-14. The variable incidence wings are fully functional, and are actuated by action groups. This is mostly non-problematic, and the wings dock back without incident, provided that the transition is done in level flight. The focus for this project was extreme visual accuracy, so the craft is extremely draggy. Because of this, expect top speeds of about 100m/s with afterburner, and about 170 with burners lit. I expect that it will perform much better in FAR, but have not tested it. Fitting to the real Tomcat, this replica is significantly more maneuverable with wings forward, and a bit faster with the wings swept.

Stock 1:1 F-14 Tomcat The F-14 Tomcat is one of the most iconic U.S. fighters, ranking along the P-51 Mustang, F-86 Sabre, and the F-4 Phantom in the lists of the greatest fighters of all time. Its wide versatility, immediately recognizable swing-wing, and appearance in Top Gun add to its appeal. In the air, the F-14 was a Mach 2.2, carrier based fighter-bomber designed with experience fighting MiGs in Vietnam. As a capable dogfighter, the F-14 earned 160 kills versus only 10 losses to enemy fire in the Iran-Iraq war in the 1980s. And now, finally to you, so you can take the highway to the danger zone while reliving tales of aerial combat and trial by fire. This is a 1:1 scale replica of the F-14 Tomcat, complete with a pair of air-to-air missiles and swing wings. Controlling the wings is simple. Simple use action group 1 to toggle the wings forward, and action group 2 to toggle them backward. Note that you have to stage to release the wings first. Most of the time, the wings should snap into position by themselves, but sometimes you have to adjust the limit on the airbrakes manually in order to move the docking ports so that it docks. The F-14 can be flown without/halfway docked wings, but landing and time warp are discouraged. Takeoff is really simple. Pitch-up at 40m/s and it's off like a rocket. Landing is much harder. To land safely, come in really hot, at full throttle (non-afterburning), above 120m/s at a low glideslope. As soon as the wheels stick, kill the throttle and brake hard, and it comes to a stop quickly. Guide for Aerial Combat: Due to the magic of Target Hold on SAS, it is very easy to control a large number of craft in the air at the same time. When I was flying my dogfights, I had a single "lead" aircraft that each of the other craft were targeting. This made flying the entire swarm around very easy, once they made it into the air. Getting five planes airborne at the same time was a feat in and of itself. My method is extremely quick, and requires lining up aircraft slightly farther apart than their takeoff roll (this is extremely easy with the F-14s, which take off in under 200m). The intent is so that as soon as you lift off with one craft, you are passing over the next one in line (within 200m), so the entire chain takes off before the lead plane passes the end of the runway. From there, it is merely a matter of maintaining speeds (ideally, they should be equal, but 2-3m/s is excusable) so that one plane doesn't turn into a guided missile. From there, simply have the lead plane make a hard yaw to spread out the chase planes, and begin dogfighting. In order to fire the missiles, decouple them and select the target and the target hold on SAS. After you have done that, you can switch back to the F-14 and continue flying. The missiles are fire-and-forget, so multiple can be targeting a plane at the same time. This can lead to swarms of missiles chasing their target, as for what they lose in accuracy, they make up for in flight time. Often, unless the probe core is destroyed, they will follow their target all the way to the ground. I am also including the F-5 (or MiG-28, if that suits your fancy), as it has a very comparable top speed, and is armed with two unguided rockets. They can make excellent target dummies adversaries in dogfights. Download Links: F-14: https://kerbalx.com/servo/F-14-Tomcat F-5: https://kerbalx.com/servo/F-5-Freedom-Fighter I would like to give a massive thanks to the people upon whose shoulders this was built on, first and foremost @Torquimedes for his own amazing stock F-14, which inspired me to begin building swing-wing aircraft in the first place, and also to @Jon144 for designing the bearing which I ultimately used on the F-14 wings. Enjoy! -Servo

I've read that the way to build this aircraft is with Infernal Robotics, but there's nothing infernal about this one. It's pure stock. After building the Moller Skycar I had a notion how to make the wings work. I started with the Skycar’s butterfly hinges, added wings, and removed the pistons which were so prone to breaking. The wings swing fore-and-aft reacting to speed changes like a real Tomcat. I had trouble with the wings twisting until I remembered that Tomcats have "wing gloves" that fit around the base of the rotating sections, so I built those, along with the "wing deck" on top of the nacelles to restrict wing motion to one axis. You can see both features on this Tomcat: Here's the wing glove/deck: I thought I was done at this point, but wanted a go at synchronizing the wings as well. So I added some solar-panel gear teeth to each wing hinge that engage in the center section, and another to restrict the arc of the swivel, and the wings move in unison now. Here's an exploded view of the mechanical bits: The thermometers hold the hinge axles in place inside the engine nacelles. The wings are attached to the lower end of the hinge axle, and the solar panels to the upper end. The solar panels mesh in the center behind the cockpit to synchronize the motion of the wings as seen below: After the early versions were so fragile, I was amazed how simple and stable operation became after these changes. This Turkey(1) ended up working as I expected and is also fun to fly! Yes, I did listen to Kenny Loggins DANGER ZONE on a loop for the three solid days it took to build and test this. But when Youtube wouldn’t allow me to use Kenny Loggins, I discovered DANGER ZONE by The Sinners. Operation: Engage SAS. Throttle full. Stage. Leave the ground as quickly as possible to avoid injesting a squirrel and stalling one of the engines. This plane can be squirrely on the ground. Watch the wings sweep back as you gain speed. Snap roll or decelerate to extend them again. Stir in afterburner to taste with action group 1. You have about 20 minutes of fuel, or 6 minutes if you feel THE NEED FOR SPEED. Mods EditorExtension and HangarGrid were used during construction, but the result is pure stock, so it should also be usable on consoles.

"Project Sentinel" Landing the S7-F14 Tomcat on the Aircraft Carrier Sentinel (Update: Video was blocked, song was removed, sorry no music for now.)

Sector 7 Space Laboratories - Aeronautics Division In my previous release of the S7-F14 TomCat I had landing speeds that were high and making the craft difficult to land and takeoff. I now have speeds under 100 m/s during takeoffs and landings. It's still not the handling that I would like to see for this craft but it's flying great. The fuel was reduced, Airbrakes were added and also Canards are hidden in the fuselage for added control. After getting tips from other builders @Hodo & @pTrevTrevs this craft looks better and handling better. Each version has it's own wing position. I plan to build an Aircraft Carrier to support these craft in the future.
