My list and why:
-T-16 Skyhopper... While the interior needs major retooling (flight controls would be fantastic), the ship is arguably one of the first to-scale new sculpts we've gotten in the modern line. It's got a ton of detail, and while I'd have liked one with an opening hatch off the side and realistic flight controls/interior, it is to-scale and that makes the interior a customizing project to me.
-A-Wing (POTF2)... The A-Wing was to-scale from day one, and Hasbro actually put it out with improvements. The side guns push in and lock into the "fixed forward" position (I never have bought any bull**** EU that says the A-Wing has pivoting guns. Didn't in the film, so no reason to other than a toy said so). The ship's landing gear were much sturdier than the vintage ship, the paintjob was fantastically accurate to the prop it was designed on...
And holy hell a 100% newly sculpted pack-in figure? Yeah it's not accurate, but it's a WHOLE NEW SCULPT! Where'd those days go huh?
-A-Wing (Target/Saga)... The repaint of an EU Green Squadron A-Wing is just amazing that it even happened. The markings are nice, even if the ship wasn't anywhere on-screen. As noted above, the ship is accurate in scale, and improved in some of its features with the guns and gear getting an improvement. The paintjob on the green squad ship is nice and adds diversity to any hangar bay... The sculpt of the original toy even had pop rivet details on the armor which is really ahead of its time in realism. Neither version of the ship was a real pain to find either, and I even got multiples of the POTF2 one on clearance for a nice hefty flight of interceptors (A-Wing's designation for the un-nerdy among us). Even managed a 4-ship flight of the Target one after they hit the orange tags.
-Luke's Landspeeder (Saga)... The surprise hit vehicle of Saga, aside from the A-Wing, was the out-of-left-field complete 100% resculpt of the Landspeeder. With accurate paint, lots of accuracy in the sculpt, and finally being done to-scale as well, it's a great piece. The exposed port engine is just a thing of beauty what with its multi-piece construction so the wires and such look completely realistic.
Couple that with the rifle clip (NICE!) that's an accurate touch, and a pack-in that wasn't shabby (shoulda just packed the floppy hat luke in with all his accessories and the clip on his belt, but whatever), then that's pretty sweet work. It's a great vehicle.
-TIE Bomber... The TIE Bomber is absolutely fantastic, and was a hot HOT ship when it came out. I know I bought 3 on opening night for AOTC toys when I found them, and they sold through subsequent replenishment just as fast. Even the battledamaged paint variant sold through well.
The paint variant was a lame paintjob, but it was nice to see a ship that literally flew out the door back on the shelves again. And at $30 the all-new and in-scale sculpt was welcomed warmly. I even liked the TIE Bomber's action feature that didn't intrude with the overall look of the toy, worked (it's simple enough that it should) and the bombs even look cool. It's one of my favorite toys and I managed 4 Bombers total for one devastating flight over any battlefield. I have to say that I almost wish they'd had a Torpedoe Firing Feature from the ordinance pod though, but whatever. I'll live.
-TIE Interceptor... The wings are good, they're sturdy, and while the ship isn't perfect by any means due to the cockpit pod being the battery-compartment version, the ship is still a solid to-scale sculpt with lots of detail. I have 3 Interceptors thanks to a nice loose one I found at the local Toy SHow on sale for less than retail. Sweeeeet.
The Interceptor just needs released with the right "pod", however I don't even know that I'd wanna shell out what it maybe would cost since the ship was in-scale in the first place and the pod's only slightly bothersome to me. I'll just call this the long-range variant.
-MLC-3... Yes, I did it! I dipped into the vintage pool for something I consider one of the neatest vintage vehicles. THe MLC-3 is a believable (the most believable) looking mini-rig IMO. It's something I've adapted to the modern line even and buy up damaged loose ones if I see them cheap. Love that little bugger and have customized a few over the years with spiffy paintjobs and extra stuff. It's the Alliances answer to the Imperial AT-PT I say. Yes my imagination is running wild.
-Stass's BARC... ROTS has dished out some great vehicles itself, probably the best assortment of any of the films, and while the first BARC was a weeeeeeeaaaaak effort at best, the to-scale version Stass Allie comes with is amazing. Working "gear" so it sits nicely, comes apart, lots of detail (paint, sculpt, etc.), sits a figure well... Stass sucks as a figure, but the bike's sweet and hopefully BARC Troopers in the future are SA and can sit on the bike, or we get some Neyo grunts (and/or Neyo) for them? I love this toy!
-AT-RT... Sticking with the ROTS theme, the AT-RT was a surprise to me... The vehicle is to-scale, and is nicely sculpted. Its flaws are "minors" to me, like the paintjob could use some sprucing up, but it's really nothing terrible either. The walking feature is lame sorta but it's got a level of humor to it too. The pack-in was probably the only real disappointment and we got that ass replaced anyway.
-Tri-Fighter... Got the shaft in the film, but boy what a toy! The Tri-Fighter's big, complex, heavy... Had those neat buzz-droid figures too. It's to-scale too which surprised me when I checked its measurements with the source material on it. Gotta love that.
There's several ROTS ships I don't have like the Jedi Fighters or Wheelbike but I'm guessing they're actually accurate. Hoping to nab these loose to measure first though before I commit to buying.
-New TIE Fighter... Measured it, and compared to specs on the TIE, it's 1:19 scale. Since the figures have never had a set scale, and most actually come in closer to 1:19 than 1:18, the TIE Fighter is spot-on. Love that fighter. The beefs with the new TIE are few and far between really... The pilot and price were my biggest complaints, with price being the tops. Other than that, if I find a 2nd one I'm buying it so long as I can afford it.
Love this ship.
-Vader's TIE (Potf2/OTC)... Don't own the OTC but should've bought it. Anyway, it's to-scale as well, and fantastic. The all-new sculpt for the Vader's TIE was a surprise at the time and it has a nice interior sculpt too (like the bomber). The ship is really nicely made though, looks good... A nice centerpiece with other fighters. I desperately need that 2nd fighter for flanking the Advanced x1 though.
-EU Airspeeder... Another one for the "It's to-scale" column, or at least it looks like it is to-scale in every pic I've seen of this design. The EU Airspeeder was a concept design from McQuarrie for the Snowspeeders, and then the EU adopted it as an actual design in the SW universe... It's a single-seat combat airspeeder used by the Alliance extensively. I have a number of these I've picked up on clearance over the years and love them. It's nicely sculpted, lots of detail... Needs painted up but that's ok. Great ship and fun to have a flight of them heading out to do damage.
-EU Cloud Car... Same as above. The ship is nice if you can buy into anything EU, and it looks sharp next to the vintage 2-pod cloud car (another ship for this list). This is the single-seater version I guess and that's fine by me. I have a CC Pilot in there (OTC one) and he looks just great.
-Vintage Cloud Car... One of the most overlooked toys from the vintage line, the twin-pod cloud car is amazingly sclupted. It too has the great pop-rivet detailing on the armor panels, nice little blasters sculpted into the pods, a nice cockpit lid with "Glass". It's just a sweet ship, and one I wish we got re-released for the modern line. I'm set to buy some vinty ones for repainting though. Oh, forgot to mention, it's to-scale even... Can't argue with that in the slightest.
And with that I'm gonna cut my list short...
My top WORST ships though I want resculpted:
-Speederbike (released in Clone Wars and ROTJ colors)
And I'd add the X-Wing if I thought they'd do it, but with them whoring the FX sculpt out so much I'd never count on that.
These are all ships that are noticeably underscaled and iconic enough that I want them to be done to-scale. They're all "possible" in the modern line, thus I didn't list Sandcrawlers or AT-AT's (I know they'd not even be possible), and they're the ships I enjoy the most from the films too actually... Probably my favorites, especially the X-Wing and AT-ST. The Gunship and Skiff have huge figure interaction potential though so they'd be the "funnest" of the list.
Ships I think that are good but aren't to-scale so I don't list them though, but are good "toys", are as follows:
They're all 4 ships that are high quality in every aspect except scale. I'd love a to-scale Gunship though given how they were close really and it deserves it probably more than most anything from the prequals. It's a ship they should've done right the first time IMO, but I'd never expect a resculpt on any of those 4.
So that's my take... Hasbro doesn't do great vehicles often in my POV but they do good toy ships often enough I think, though they claim ships are generally for adults, not kids, so I think accuracy and scale take precedence over "features" and whatnot.
I've bought $40 and $50 tanks and airplanes, and believe it or not they're heavy with licensing fees, and they blow Hasbro out of the water on even their best vehicles I listed. No comparison what-so-ever if you could see these and see the complexity in them. Hasbro can do better in the vehicle line I think, but I've gotten to the point I pick and choose out of vehicles rather than feel compelled to buy it all. They lost me on completism with that a long time ago.
