So, I just installed the Estes App on my iPad....and noticed an additional rocket listed with the skill level 4 kits. You can't see it from the web site and following the "Additional Information" button gives a 404......
Over the years Estes has made some mysterious decisions regarding the Sat V and at this point not much would surprise me.
Some of the new E and F motors they've introduced in the last couple of years would seem to be ideal for some of their maxi-size models they've dropped from the lineup.
Most of those models have never really flown well with any of the previously-available BP motors.
My own guess is when we come up on the 50th anniversary of the actual Apollo flights in 2017-2019, it would make sense for the Sat V to make a reappearance.
