Looking back through Estes kit release history,
1. Of all the kits they haven't re-released,
2. that date back to the 1967 - 1987 period (thanks GH),
3. and seemed to stay in production for 10 or more years

I get the following ranked by years in production

1. Scout
2. Streak
3. Sky Hook
4. Farside
5. Phoenix (1380)
6. WAC Corporal
7. Drifter
8. EAC Viper
9. Mark II
10. Mini-Brute Beta
11. Mars Lander
12. Mini-Brute Screamer
13. Cobra (classic kit)
14. Falcon (glider)
15. Sprite
16. Shrike
17. Maxi Pershing 1A
18. Renegade (1271)

Not exactly a list filled with this crowd's top picks, but these are what stayed in the production the longest (that Estes has never reissued). Arguably the Scout (Scout III) and Streak (Maxi Streak) were reissued, but that was already a long time ago. It would be nice to see just about any of these as bring backs.

If I had to pick from this list my choices would be the Mini-Brutes, EAC Viper, Mars Lander, and the 1271 Renegade (an upsized version would be nice). I’d pick the Farside-X over the original Farside and, just to be a contrarian, a downsized Maxi Pershing flyable on 18mm motors 😆

Edit - oh, add in a Super Sky Hook, it’s a classic 3FNC and just different enough from an Alpha to be interesting.
