I built the F-14 designed by Matagami Designs. It fly great and be able to sweep wing in mid flight. Hope the link works.

After the secong build. Im trying to make the second f-14 on the upcoming fall, its going to have many improvements over the current one. I also have constructed a cnc router this summer, its definitely coming in handy cutting the foam and the new wingbox which will have gear teeth for the sweep. Maybe even some vinyl decals?

How did you make the cnc I've been wanting to build one?
I love these plans! I've built this same foamy 3x now over the past 10 years. I just built this one and it's the best one yet.

That looks great! i love the Jolly Rogers livery.
Thanks! The original designer was Maybz on RCGroups. If you look at the pictures you'll see the wings swing forward and back just like the real F14. I mixed the swing-wing with the throttle so as you go faster the wings sweep back.

That's a great idea!

One more flight video of the f-14, this time with a gopro attached on the top. This flight was not as good mainly because I had very little space to fly due to a farmer driving his tractor one of the fields in the middle of the crops. Also it was quite windy, luckily the gopro has an unbelievable good image stabilisation. The sad news are that this was the last flight of this jet. I am going to disassemble it soon. That's the spirit of prototyping, one has to be ready to make sacrifices to build something new.

Not really, I have been slowly prepairing the plans for the second version and also I have been familiarizing myself into cutting plywood with the router as the new sweepable wingbox will be completely cnc cut just to make it more weight optimized. Its getting close

Im slowly starting to build the tomcat 2.0. I have redesigned the wingbox and started to build it. The 8 foam sheets are finished and ready to be converted into gcode. For the sweep Im using two ds-239hv servos one of which I have reversed. Here is all the stuff that goes in this jet. Im probaby going to add rudders and flapperons in this version, Im definitely not sure if its worth the weight but I want to see how this model behaves with the added funktionalities. The flapperons would work only in forward sweep flightmode. I am currently converting my cnc to belt drive so the next update will take some time.

Great!

You are right this jet is definitely not the easiest one to make. This f-14 is meant to be a high performance jet so the wingbox needs to be very stiff. But stiffness costs weight... No way around it. Im aiming for 1700-1800g for the total weight.

I agree with Vincetel F-14 (above) since I not only made that swing wing aft, i used the same plan to have a design that doesn't exist. That design is super tough and flies not only can be moved aft, it morphs to fly swept forward controlled by the throttle. His simple 1 servo design has a large weight bearing area that allows easy movement of the wing.
If you look below and follow his exact positioning of servo, arms etc, it will not bind up on you. I added graphite powder on my surfaces to mine so I can get the wing to move forward as well as aft.
Maybiz on RCgroups allows downloading so you can have a F-14 with a movable swing wing by throttle. It is simple and fool proof. On one arm I added a threaded setup so when the other wing touches, you can adjust the other wing so it does the same. Look for MDC F-14 plans and pic in the pusher prop section.. Vincetel does a nice job of decorating his, mine not so. Still have it after many years.
