      I am about to begin my Minicraft 757. Anything I should look out for? I am up to speed on the tail fix and the engine pylons. I suspect, however, that there are other things I should probably know about. For example, what is the story on the uneven wing roots?

      I am working with the Air Force 2 kit with the P & W engines. Anything here I should look out for?

      How is the nose?

      Thanks for your suggestions.

      Hello:

      Pleased to meet another 757 fan there. I have built three of them 8with the 4th on the process) and I like the kit. It is somewhat tricky, specially the RR engines (I replaced them with the BRAZ ones) but the PW are acceptable. The nose is its weakest point and it is difficult to work specially for people unfamiliar with 57`s, however since my first kit I was succesful with the nose and had no problems at all. With some sanding it can be made to look like the real one. Now moving to the wing roots, I found that to be true (when I tried to align diehdrals) but very difficult to notice. Anyway it is a kit I like and about more 10 are awaiting in my collection to be built (AM old and current colours, MX current and retro, BA world images,3 acft, Eastern, Ethiopian, AA Retrojet, and a Condor 300 conversion). The next one to exit the paint shop ia a Continetal 200 just in time to conmemorate 10 years after my first trip alone to New York (I was 20 right then!!!!! and the 757 smelled like new!!!!).

      Finally, I would rate the MC kit on the same league of an Airfix 737, it is basically good but it has lots of room for improvement.

      Oh oh ...

      I forgot some bits:

      1) Door 1 outline is wrong but I suggest fill all outlines and use decals.

      2) Fin is too slanted, sand to shape or add some plastic to reshape.

      3) Wing trailing edges are quite thick, sand them before gluing wing halves.

      4) Sand pylons a little bit before installing them, they point too much upwards.


      and yes.... the DC 10 rules!!!!!!!!!

      Hello again:

      Basically the transparent cockpit piece has a huge step between the radome and the ramining fuselage. If it is not sanded carefully it can get a strange shape with no relationship to a 757. I did the following thing; I visited airliners.net and after finding a picture of the 757 nose profile, I printed it and pasted next to my workplace. Then I sanded the transparent part as well as the fuselage until a convincing fit was possible. The 757 has a very distinctive nose which points downwards (hence the "bird of prey looks"). Radome is more pointy than the A320 or the fokker 100 and with careful observation it looks like a modernized and widened 727 nose. All I would suggest is a lot of "dry fitting", observation and testing before glueing anything. then after putting all together use MR Surfacer to hide any gap or hole that remains. My first 757 was not as good as the 3rd one but neverthless with her Air Holland colours looks nice.

      Good luck and don`t be afraid of experiments,

      Hi Albrecht,

      My first 757 that I finished (Royal Airlines) ended up with a tail that was leaning over. It was sitting on it's landing gear with wings level with the ground. For the life of me I couldn't figure out what I had done incorrectly. After much discussion with experienced modelers we figured it out. Using a home made alignment tool for airliners it showed the error of the Minicraft 757 kit. If you build the kit out of the box line up the wings properly with the tail fin. Then set it on it's landing gear with wing tips at an equal distance from the ground the fin will be leaning over to one side. This due to the fact that the wing fairings( and mounting points) are improperly molded on the fuselage. The only way to correct this is to chop the nose and tail off and reglue them on with the proper alignment added.

      Other than the alignment and engine problems it can be made to look like a fine Boeing 757 with a little work.

      Cheers

      Hello Andrew:

      I found the very same problem in spite of a very careful assembly and at the same time some panel lines were misaligned (never mind, I have my scriber always close). However at a first glance I attributed the slanted fin to an unnoticed incorrect assembly. After building my second 757 I became more puzzled but instead, using hot water, I "aligned" the fin. Anyway, it still loked strange. So maybe I shall chop off the tail and nose the next time.

      Now... i should finish my CO 757.....

      Wings:

      I have been dry fitting my wings and fuse, and everything lines up? Did Minicraft go back and fix the molds at some point? Or when the model is assembled it will still lean to one side? Would it be possible to cut the tabs off and glue the wings correctly? How much are they off? Should the left wing be raised or lowered 1mm? 2mm? Should the right wing be raised/lowered 1mm? 2mm?

      Nose:

      I see the step in the transparency. It looks like light filing and sanding will correct this problem. Otherwise, is the nose/radome large enough? I was thinking of building this up with primer/putty and creating a slightly bigger nose?

      The 757 kit has not been retooled.

      It's the whole wing fairing that is not mounted properly on the fuselage.

      I mounted the wings lined up with the tail and horizontal taliplanes. It looked just perfect. Now go and try to stick the landing gear on being sure to keep the distance from the bottom of each wing to the ground equal. It won't work the tail will lean to the left side(looking from the nose to the tail).

      I don't know what the differences are in mm as I haven't measured it.

      The only way I have figured out for a fix is to cut off the nose section and tail section. Then rotate the center section and re-glue sand and fill.

      Many folks build it out of the box and it still looks like a 757. So what ever floats your boat.

      Cheers

      Hmm. Maybe gear up? That's how I used to build 'em before I grew up and got serious. Never used to like the gear down. Maybe I should "loosen up" and give gear up a try?

      Does that fit correctly? I ask this because the 757's cross section isn't a circle, but has an oval shape.

      Do the RB211s from the Revell 767 kit fit the MC 757 wings? If they do, I have found a purpose for the RB211s I have.

      I put the RRs off a Revell 767 on a Welsh 757 about 10 years ago and they looked way oversize for the 757, at least to me.

      This is true. The 767 RRs are too big for a 757.

      Is there a topic that will get me up to speed on all the Minicraft 757 issues not mentioned here? I'm not aware of the tail fix and pylon issues???

      Hi everyone,

      Since I haven't seen any negative comments on any of the forums, can I assume Welsh got their 757 right? In addition to what's already been posted, here's a couple of things I've found in comparing the Minicraft kit and the Welsh kit:

      - Minicraft's right wing is over 1mm thicker than the left one at the wing root, so that the top of the right gear well is higher. This causes the model to sit with the tail cranked over to the side, even if you align the bottoms of the wings properly. The fuselage fairings seem to be aligned OK.

      - Assuming the Welsh kit length is right, Minicraft's extra 5mm in length is mid-fuselage. The wing fairing is longer than Welsh's. The leading edge of the Minicraft tail starts the same distance from the tip of the radome as Welsh's tail. The trailing edge of Minicraft tail is the same distance from the aft tip of the fuselage as Welsh's. This makes the Minicraft tail 5mm wider in chord than Welsh's.

      I thought the building Welsh kit was less trouble than correcting the Minicraft kit, especially if you throw out the kit engines and replace them with Braz engines. Welsh is re-releasing it with better resin parts to replace the less-detailed injection-molded plastic, so this may be a better, but more expensive, alternative to the Minicraft kit.

      If somebody who knows more about 757s than me (that won't be too hard because I'm nowhere near being a 757 expert! ) comes by and says the Welsh kit is wrong, just ignore this post!

      Cheers!

      I'm about 80% done on my first 757 build, and having built it out the box with no actual fixes, am (Not sure what word to use here) waiting for all the known issues I've read about to pop up. So far everything looks good, but I anticipate trouble when it's time to attach the landing gear. I'm already messing around with the pylons to get the engines sitting a little lower. It looks like a 57 to me. The most obvious thing with this kit was the bad fit/wings to fusulage. Had to throw in a good amount of putty in there, as the gap is very obvious. I've had a good time putting it together so far. Beats working with the small little parts I was dealing with on my MD-80 kits.

      Is it me or were the flap guides also a not so good fit? I was able to fix up the wing and engine to pylon seams, but the flap guides, I had no intention of throwing putty in there. Are they designed to fit onto any side of the wing or are they left/right specific?

      One more issue to be aware of is the fit of the horizontal stabilizers, mainly the unequal angles at which they attach. Even though I bent the tabs as much as possible (short of breaking them off) in attempting to correct and even the angles, the stabs still attached at non-symetrical angles. It may be necessary to remove the tabs or trim them very short to get the stabs to attach at proper dihedral.

      As for the landing gear, from what I recall from the Mincraft AA 757 kit I built (Icelandair livery), the attachment of landing gear legs/struts, wheels and doors were about the only straightforward fitting parts which required no additional work to achieve a correct-looking fit.

      when you say flap guides, are you speaking about the fairings over the flap tracks, also known as canoe's. on the real A/C they are Lt and RT. inbd and outbd. also there is forward and aft to them.

      Hello Ace,

      I have 2 757's under my belt which does not qualify me to the level as some of these guys. Nonetheless I did learn a few lessons I am more than happy to share.

      1. Getting the engine to attach to the pylon took some work, putty and time,
      2. As stated above the stabalizers are not level with the wings.
      3. Also stated above, the wings trailing edges need shaving.
      4. The front landing gear tilts a bit forward. I think this is normal. The strut of the real plane does not really tilt forward, the ocnfiguration of the components housed on the strut give it an illusion that it tilts a bit forward. Here is a few pictures so you may jusde for yourself.

      Hope this helps some.
