    I bought that stuff and it seemed pretty stiff and not really that flexable,and wasn't able to make a good bend for a controle surface hinge,I only saw one there on H K with no other thickness available.You gave me the exact item page to go to for it.

    Yes indeed, FBK. Jimbosflyin has somekind of magical touch when it comes to constructing his planes :D All look like storebought ones.

    Without Wildthing and jimbosflyin, it's possible to make this A-10 comes true FBK. I don't deserve the credits alone :)

  4. Well start of number 2 snowflake. ;) Building at 105% this time because Jimbo said to :). Designed some 3D printed engines, very thin and lightweight and should have very little wind resistance. It's fast already so it will be interesting to see if there is any gain in speed. Going to see If I can hide 1 single servo inside for the elevator.

    Oh my. You boys two have been busy already building the second ones? :D hahaha! Feeling guilty of haven't flown mine.

    So I need to get myself busy as well with the next candidate then. The Mitsubishi F-2A (G2R).

    Similar to F-16, but having bigger wing area and horizontal stabilizers as well. Thinking of having rear mounted pusher too. I think this would give slight difference to the F-16 G1R we had earlier. The only thing I imagine now is that, I may not be possible to have under arm launch as it doesn't have enough grip on top the fuselage to toss the F-2 in the air. Or, ... we could do something about it without being compromised. Hmmmm ..... :rolleyes:

    I managed launching it two different ways. WIN_20181101_01_19_42_Pro.jpg WIN_20181101_01_19_21_Pro.jpg
     
  8. I just hold by the top side of the nose and underhanded chuck.
     
  9. The building of the new 1 piece wing. :)

  10. Little progress this morning. Dry fitting the fuse and trying to figure out where I can hide a single elevator servo and putting some of the small pieces together.

  11. Well figured out where my single rear servo is going, just enough clearance between the engine mounts once they are mounted. it is actually mounted to the underside of the plate and because the bottom plate goes on last no rush to run the control tubes. Once the glue cures I can drill the holes for the tubing and run the wire through. All the holes are cut where to pull the wires through. I figured while it is apart might as well do the wedge filling too.

    Hi FT my good friend :) Many thanks for the kindest support and warm words. My family are so grateful knowing you're now much better.

    Seems like everyone at PI is busy this weekend. No a single flight for me as it's raining so the new A-10 has to sit on top of the table waiting for its maiden flight.

    Anyhooooooooo ............ my fingers are simply busy on the keyboard and mouse, so here's the progress F-2A Viper at this very moment. Wouldn't be harder than the A-10. It inherits the same wing construction as the SU-30SM. We (jimbosflyin, Wildthing and me) are excited about this next project. Hopefully the A-10 would be available during the year's end holidays to keep you all busy too :D Would be a tough choice between F-14D, F-15SE and A-10 Thunderbolt II.

    I plan to draw the panel lines today, so the A-10 would look better in her cosmetics :D

  14. Well elevator control lines are in. Trimmed and sanded for the most part and dry fitted everything except the engines.

  15. Here it is dry fitted with the 3D printed engines. These guys are less then 1/2 the weight of the foam built ones and almost 0 wind restriction. Aileron servos I angle mounted them this time so I can have a straight control rod. Now to start assembling it. ;)

    Just one thought Jeff,your contole wire isn't going to be square with your hinge and will be pushing a bit sideways on your controle horn.

    really nice,i must get into this 3D printing.
     
  18. Control horn will be square with the control surface, the rod will have say 1 20 degree bend in it close to the control horn.
     
  19. Control rods almost installed but with a slight glitch, front works perfectly but the rear not so. I kept the control horns straight and bent the wire but that created a twist/bind in the wire and the elevator didn't want to center properly. So will cut out some new elevators and remount the control horns at an angle to match the wire keeping it as straight as possible.

  20. New elevators are on and control horns in, now to wait for the epoxy to cure and see how it reacts now.
