      I've got an half built RAF Hasegawa Tristar that I'm gonna convert to the 'proper' size for the RAF tankers, this model is one I started building about 10 years ago then discovered it was not the right type for the RAF aircraft, so it sat on the shelf gathering dust.

      So what to do? These are the changes I will be doing:

      1) Shorten by 6 windows in the front
      2) shorten fuselage by 2 windows in the back
      3) Blunt down the wing-to-body fairings in the front
      4) Blunt down the wing-to-body fairings in the back
      5) make a intake fairing thingy for the number two engine
      6) lengthen the main wings a bit.

      anything else?

      Oh, BTW it will be ZD951 as

      1, that aircraft was here in NZ in 1987 (the first time I ever saw it)
      2, that aircraft was at RIAT2013 (most probably the last time I will ever see it).

      George,

      5) It was called a Frisbee Fairing and used to reduce noise. It prevents the boundary airflow from suddenly seperating around the earlier pylon shape, which created a lot of noise about the rear cabin.

      Also, remove any hint of a tailskid and housing. http://www.tristar500.net/specifications.htm

      You'll also need to revise the hot sections of all three engines. The Hasegawa parts represent an earlier, longer tailpipe, but all -500s I've ever seen carried the shorter exhaust seen on just about every L-1011 after the late '70s/early '80s. Not a difficult modification, but definitely noticeable.

      Thanks Scott, and ah yes thanks Jodie, forgot about the engines. Yup J, sounds easy, but it's more a case I'm the mad professor and the product will end up a Frankenstein. So far I already made one cut in the wrong place... doh!

      will chuck up a few pics soon to show y'all.

      You would also have to increase the angle-of-attack/incidence of the wing-mounted engine nacelles......

      Cool thanks Billy. Below are some progress pics.

      I chopped out the front and back sections:


      At the back I made the the cut thinking I could work around the fairing but realised that was a bad idea. So I stitched up the cut and re-cut just under the intake. I think it is a better place to cut because I need to re-shape the aft fairings anyway. Quite a bit of shaping and filling to do...



      I've started on re-shaping the the fairing at the front. Luckily the plastic on this kit is fairly thick, so I am trying to avoid cutting through if I can, saves on filling.



      Have glued the sections back together and made some wing extensions. Already it looks much better than it did before.


      Next up, I will make the "Frisbee fairing" (Thanks Scott!) and fix up the engines.

      Excellent work George; don't forget that the RB-211-524 engine intakes had a sharper lip radius too (but I do not know if this applied to the centre-engine intake too)......

      Bump...reviving this old buidl thread I started...back in 2013!

      7 years later and I rescued this model from the shelf of doom (for the second time). I never liked the blocked no. 2 engine intake, so off with the tail and some re-work.



      Used a bit of aluminium tubing for the intake, and joined it with a cut-down sharpie case. Yes I know it's not "curved" but its good enough for what I want. Plus it looks way better than it did before.





      Got this little guy to help put it back together...


      It needs a tidy up around the intake entry but overall I was quite please it turned out OK.



      Next I had to make a Frisbee Fairing, so I used a bit or styrene to made a wedge. When the glue had set I cut it down to fit it.


      The next step was to sculpt the fairing, this was a little tricky but I persevered until the shaped looked ok to the eye.


      Once the putty has set, just was a matter of filing and sanding.


      I have given it a spray with some guze paint I had lying around, I thought it was matt, but no. But overall, this model which was originally destined for the dustbin, is starting to come back to life.


      Next steps are to get the work done on the engines to shorten the hot sections. I'll try not to let another 7 years pass...

      Update:

      I found my Frisbee fairing was slightly off-center, and it was annoying me, so off with its head!



      I will get to work on another. Hopefully will be able to get the repair done tonight.

      Hello,

      Impressive conversion, I like the way you did the frisbee fairing, even if you are redoing it. I am surprised the plastic is thick to the point you could sand off the wing-body fairing, that is a good point. Todays kits fuselages are much thinner (economics?) and such work would imply backing with plastic sheet.

      I never had a Hasegawa TriStar kit, is it as accurate as their 747 and DC-10 kits ?

      I always loved the shorty TriStar, odd-looking in a good way, IMHO just like the 747SP.

      Cheers, Stephane

      The #1+3 engine fairing also had a modification on the front where it met the leading edge of the wing.

      Thank you all for the comments.


      @RB211-524: I believe the Hasegawa kit is accurate, though it comes with the early long type RR exhaust nozzles


      @FLYHY
      : I looked at a few pictures on the net, to see what you meant about the fairing, but I couldn't quite see in various photos. Can you provide a link to a photo? But I may not bother doing it, I'm guessing in 1/200 scale it won't be prominent.


      @Ahmed: Its going to be the white scheme with the refueling probe above the cockpit.

      After re-making the Frisbee fairing, I have to wait until the putty has cured, so I started on the engines:

      Don't know where you 'learned how' George... The pictures make the complex conversion you are doing look easy in spite of admitting you made a cut in the wrong place... which reminded me of another Jennings quote, pertaining to shortening/lengthening a fuselage: "measure twice and cut once." (from at least one of his Liveries Unlimited decals having options to do different variants of a basic type, ala 737NGs)

      some more (slow) progress pics, I have got the Frisbee fairing back to something (I think) respectable. All primed and ready for a top coat. I will start with painting the wings, and will use the excellent Nasca Decals detail set.

      I broke the end of the refueling probe off. Grrr. Will glue it back on later. Sorry for bad pics.

      Not perfect by any means, but I used Tamiya acrylic which I have never had much luck with, but I managed to get good results.

      However, after comparing several references, I realised I had glued the refuelling drogue things a little bit too far forward.

      So off they came, lucklily they were easy to get off.

      thanks Merlin. Yep,it's been a long build for sure

      Started decalling with the kit supplied decals, but uh-oh! They have yellowed (well considering they are about 20 years old...) and just don't look good against the tamiya white. What to do?





      The yellowish in the roundel just looked terrible, so I decided to "quickly" (is there ever such a thing?) to scan and redraw the decals and print them.







      I have to admit, this build is testing me now. I have had a few problems wiith the decals, firstly getting them the right length for my 'conversion'.

      The second issue, was that the first lot I put on 'curled'...

      Lucky I can print more, but I am now waiting for the decal bonder to dry and will try a bit later.

      I WILL finish this conversion (positive affrimations...hehe)

      OK, I have given up on the inkjet decals, they are useless. The decal film tends to curl on the cut edges which makes it impossible to apply.

      This model could be heading for the "boneyeard".....(also known as trash)...

      I will have a look at painting the stripe.

      Arrrghhhh!!!! Near disaster!!!! To paint the stripe means the wings have to come off. This kit is starting to get me down.

      Quick update. I masked off the fuselage and gave a quick shot of Humbrol 104 blue. No idea if its the correct colour, but it is 'close enough' for my eye. There might still be hope for this build!








      Just gotta figure out a way to do the white surround around the roundel..

      Greetings!

      Look at it this way... With all of the building and rebuilding, undoing and redoing, you will have a, errr...so to speak, Zero time Tri Star Tanker! You know, just like a real zero time fresh from the factory new airplane!

      Your patience and skills are quite admirable I must say...and your persistence will soon be rewarded when she is finished!

      Hang in there George!

      Regarding the curling decals, I've often chopped them into smaller rectangular pieces and slid them directly onto the model from the backing paper. Not sure if you tried that, or added more decal film, etc. to the mix.
