What was the year that Quest heavily touted their "coming soon" vaporware 18mm D and their vaporware line of 29mm BP Thunderjets ?
I have not trusted a word from that company or spent a dime on their products since that FIASCO announcement. They never did give any legitimate explanation of those not being delivered. My understanding was that supposedly thousands were produced....better to sell at a loss than destroy them...made no sense nor did we ever get any explanation.
Always OVER Deliver and UNDER Promise !
If there is ANY chance of a product NOT making it to market, DON'T announce it.
Estes only had a couple minor announcements for products that did not make it since the Cylon Raider/Cygnus Probe Ship Fiascos....they "wised up".
Quite frankly though I'm surprised we got BP E and F motors from Estes which is nice, would be nicer if they were port-burners though. I thought return of the B14/B8/C5 would have been far more likely than 29mm BP from Estes.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
