A few years ago Estes marketed a couple of optional, sold separately, boosters for certain rockets that had the screw-on type engine retainers. They were called Booster-60 for BT-60 based rockets and Booster-55 for BT-55 based rockets.
It seems that Estes no longer sells the Booster-60 and Booster-55 add-ons. That’s a shame. I thought it was a good idea.
I have an Estes “Rookie” ARTF rocket that accepts the “Booster-60” add-on.
I wonder if I could roll my own booster for this rocket. Does amyone know of what sort of gadget would fit the threads on the Rookie’s engine retainer?
