Parkflyers International Expertimental: Grumman F-14D Tomcat G1R-S

Discussion in 'Scratchbuilding!' started by bimoadiprakoso, Mar 25, 2018.

  1. You said it well for this plane. Thats how I feel when I fly the shumate’s F-14.

    With wings out its almost like a trainer and is very forgiving and very relaxing to fly. But with wing swept back, its a crazy air drill and super sensitive on rolls. I had 40% expo set for swept wings flying and even that was too little I feel.
    Half swept was a good spot. Nonetheless, its a cool plane that will catch a lot of people’s attention esp. when they see the sweeping wings.
    Cant wait to see your flight videos guys!
     
  2. All going together , most of the hard work done at this point.

    Looks great man! Knowing you, you'll be flying her sometime tomorrow. :D Thought of a paint scheme? You gonna maiden before purtying her up?
     
    bimoadiprakoso and Wildthing like this.
  4. I hate coming up with ideas for painting. There is a whole of you guys including you that just bang off these fricken paint schemes in no time at all , I get stumped on one color. :)
     
  5. Won't be flying for a few days, cold front rolling in from the artic by this weekend and the temp gauge is starting to fall already.

    Did that rodent known as a groundhog see his shadow or not? :confused: Spring has arrived in South Alabama. Sorry didn't mean to rub it in, or did I? :D

    Don`t paint, it`s just bad luck and extra weight:D
    Anyhoo most US jets are just pale grey, which is dull and hard to see in the air:D
     
  9. I did like my grey Depron for that, add some decals and done.
     
  10. We are on our 11th season already. ;)
     
  11. Little more added to the structure, you will see added foam structure on the other side of the wing servos now which also gives me a spot for the elevon servos. But the wing servos will be sandwiched in on 4 sides, there is a top piece to go on yet.

    Lots of fishing to get all the wiring in to the canopy. didn't catch anything. :D

    HHmmm seems like a lot of work:D
     
  13. Not the beginners build that's for sure. :) It has tested my patience in a few spots. ;)

    totally worth it.
     
  16. Now that all the wiring is in no for the ESC. ESC is recessed into the bottom plate, fits in from the inside so some zip ties around it to build a handle to lift it into place and then spot welded it into place. Zip ties then removed and then hot glued the ESC in , If it gets to warm and the glue lets go, the ESC can only fall in. ;)

    Hi Gents -

    Cutting edge design as always.

    Just a question if you had considered rudders on this plane? I know it is not something PI normally does and I get the complexity of trying to put ailerons on a "swing wing" plane.

    However, looking at the build pictures, it is going to be a long beast with some fairly significant drag with wings extended. Coupled with having a rear mount motor and a long moment of inertia with lots of weight spread along the longitudinal axis, was any testing done in your software to see how rudders might help? I'm just wondering as you get in a turn in a bit of a wind with elevons only, all your thrust coming from the back end, no control surfaces in the prop wash if it might be a bit more difficult to keep the nose tracking straight? Being able to add in a little rudder would certainly take some of the strain off your elevons to keep the nose from wandering around more than you might want.

    Best of luck moving forward :)

    Cheers,

    Scott
     
  19. Ummmm, heavy ;) There is a lot of foam, I didn't use any epoxy except on the motor mount and magnets and the only hot glue was for the top plate, there it was so I could use it as a shimming gasket to keep the wings free.
