Thanks for the compliment. Weather permitting, I plan to fly it next week. And with streamer recovery!

Lee,

That's for the compliment.

I won't be flying the Patriot in my neighborhood.
Too many rocket eating trees.

How long before the unwashed masses get to hear the podcast?

I keep reading about an Estes 29mm E50 or so size engine. There is no such thing. The eninge in question is a 24mm E-57 engine that uses the same case as the E12 engines. Don't ask me when this engine will be available, since I haven't a clue, but it's going to be a while. Since I plan on fireing a minimum diameter rocket tomorrow using one of these engines I though I take a picture of the nozzle, so you can see how it compares to the Estes E12 engine.

Wow! That’s one big nozzle!

Thank you for jumping in here with this info and pic for us, John. I appreciate it. Would like to see more of you here!

WOW I sure hope this thing makes it to market, I for one love Mid Power Black Powder.
Back in the 1980's I used to launch 3-4 Flight Systems powered models at every launch,
the new E57 motor should be great, it would be my guess : the trust curve is around .7 of a second and the thrust will spike at around 30 to 35 pounds. I just hope that it is a lot more reliable than the Flight Systems E60. This engine will be the new balsa shredder for sure.

That E57 sounds great.
It will fill a void that has existed in SU BP engines since the demise of the FSI F100 and far less available Rocketflite F50/G110/H220.
I for one will buy a lot more of those than the E9/E12.
The only thing I don't understand is why it takes SOOOOOOOOO long to bring out new motors.

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 !
