So many want the old Estes Sapce Shiuttle lkit, the 1/162 kit#1284 with the hard to build vac-formed orbiter, that was a PITA to try to trim to glide (I saw very few glide. I saw many others tumble or spiral in, and some shuttles that aimply pitched badly and crashed on launch).
AIM HIGHER. NOT a bring-back of waht IMHO was an undersized bad flyig crappy kit. Go for a bigger better kit that could fly well. Like the 1/110 shuttle I've made in 1979 and again in 2008 as a possible kit. Estes already makes the correct tube sizes, 3" for ET, and BT-55 SRB's. Flies NICE on a D12-3.
Indeed, the 1979 model at 1/110 scale was my first shuttle stack (with ET & boosters). The Estes kit was just too small for me to have any interest in it. Then when I saw others flying them, I decided to make one of a size that was more reasonable (50% bigger) and that would fly well. Later, someone gave me what was left of one they built (that crashed or they got tired of fixing it), which I repaired just enough to use with a fan and crude "wind tunnel" to find out some pitch stability effects for boost. Also I've seen the instuctions and an opened kit so I know exactly what it was like.
Here's a thread on the 2008 1/110 model, which uses a styrofoam orbiter:

Here's a pic of it, for relative size.
Here's a video, camera started after ejection:
I know some would want 1/100, to go with other kits of that scale. But it would require new tubes, but more importantly significantly more mass and drag, so it would require an E to fly decent, and the price woudl be significantly higher too.
The sweet spot is 1/110 for a nice flying not crazy expensive kit. 90% or more of the "kit building" market is for FLYING models, to fly, at a launch, not static models to look at. It's sometimes too limiting to go for a certain scale, 1/100 is wimpy for a Little Joe-II (which was a bit small for a 18mm engine, and a bit underpowered on a 13mm engine). The Centuri (then later Estes) 1/45 (a scale no other kit has used) was perfectly sized for a nice looking nice flying model using D power or above.
Same goes for the old twin engine BT-70 Gemini Titan, with the horrible balsa Gemini capsule you had to carve the windows out of, incredibly hard to get to look half close to "right". And the pieces of clear plastic that were a PITA to try to glue together to make the slip-on fin unit. And yes, I did have that kit, and yes mine sucked.
Hell no, not a clone of THAT thing in these modern times. I do not quibble about the scale, or even the twin engines, but have massive problems with the thought of THAT mess of a kit to be "Brought Back" the same like it was back then, with no molded Gemini, and the same old "lotsa luck, sucker" clear fin assembly.
So, anyway, be careful what you ask for. A crappy old kit might have some "fond memories" that were either maybe not so nice at the time, or others had no fond memories at all of theirs that failed or were so hard to build.
