I know the story of the E15 being "kaboom" prone but never saw or heard anything of the E30s....what's the deal here ?
Were these never brought out due to problems with the E15's ?
Does anyone have any samples ?
Would like to add one to my collection.
I assume these were BP motors, as this was before Estes was associated with North Coast/Dark Star.

Incidentally, I have several E15 Estes motors NIP, and whenever I have used them, they performed flawlessly, which is NOT something I can say for my stock of FSI D18/D20/E60/F100 engines.
With exception of the F100, the FSI core-burners have CATOed on me at least 40% of the time.
The F100 has been about 20% kabooms.


Estes had been experimenting with the larger BP motors for a few years before marketing the E15s. Some of those motors found their way into the hands of a few serious flyers as a sort of an alpha test. I've heard of or seen E30's, E40', and F motors all based on 24mm casings. Matt Steele showed one at NARCON 91, though he didn't mention what the average thrust was.

None made it anywhere near to market until Estes felt the market pressure from Aerotech.
I think they were going to make a big commitment into big BP motors before they started working with Scott Dixon of Vulcan and Matt Steele of NCR to make the Dark Stars available.

So, it's possible that they were seriously considering releasing an E30 bp motor, or maybe it was just a misprint on the packaging (as none of the catalog listings mentioned it) of the T/S.
