If not piston deployment, then what???

Agreed. But it is when you forget something or something goes wrong that your rocket enjoys its final and destructive flight.

That simply happens more often with pistons than without.

For PML it is a "kit sales feature" both on initial impression and on "accident".

Well enough for me to recognise it.

If you are cacophobic, don't bend over in front of Jerry. 8-)

They'll get over it.

You just helped (and so did I).

I said it so it must be a fact so it's no longer an opinion.

I wasn't talking about you, Mr. Stein. No siree, bob.

Uh uh.

And that is a fact.

Hope I'm not getting like you know who. The world doesn't revolve around me ...yet 8-)

Chickens! : )

I own several PML Kits and have never had piston trouble yet, If you happen to fly them in winter like we do here in Michigan just leave the rocket out in the car the night before the launch with the piston out. It will acclimate to the cold over night and be fine.

BTW Frank and the gang at PML are a great company and make some of , if not the best HPR kits available.

Alright, I quit now.

Hey! I wasn't even in this thread....oh, you mean the OTHER Mr. Stein.

Never mind.

John

That's what makes it so interesting on here! Most days it's like a boxing match.........

Maybe I WAS referring to you. Hmmm?

I'll never tell.

upon closer inspection...you actually name Bob. Bob who? That's what we really want to know.

Another cancelled launch Saturday.....sheesh!

John

bob, not Bob.

Dave ain't here, man.

Randy

Yeah, I ain't here.

I add another bulkhead to the base of my pistons with another U-bolt for symmetry/cosmetic reasons. Not really necessary and adds extra weight.....
