Cesaroni Pro38 and Dual Deploy

Shouldn't be, lots of people fly this way. Remove the paper cap, pour out the BP, and plug the BP well, Blu-Tack is the preferred material over here from what I've seen.

Use the motor-ejection charge as your backup. Set the delay a couple of seconds longer than your expected time-to-apogee, and the motor will pop your chute if the electronics fail.

If you don't want the motor ejection, remove the BP. But in case it wasn't clear, don't fly the motor without the delay element. It's a necessary part of the gas seal of the motor and flying without it would be bad.

Or omit the BP and put a dab of epoxy on the hole.

Can't use the motor's charge as there is a bulkplate ahead of the motor tube.

There is a UK rocketry legend relating to this.... ;)

Also, don't forget the casing - it has been done, on more than one occasion!

It's not a legend.

YES!!!

It's ok to remove the black powder but DO NOT leave the delay out (unless you just want to cook your rocket & probably ruin the casing.

It's all outlined in the instructions (please read) and is certified. Epoxy is not required.

Occasionally in Texas and once in Alberta IIRC. Those instructions in the reload kit and the one on the case again please.

FINALLY! Something good. Ok you two, come across... what's the legend. : )

But is an uncertified field mod :)

Everything true and entertaining is secret.

Several years ago, a guy in a group over here called AspireSpace claimed he knew how to load Aerotech 54mm motors for a student rocketry championship. He didn't. He left out the delay grain, because he thought it wasn't needed. The rest is history :-)

Much to everyone's amazement, he got a PhD a few years later (in materials science mind you). Not suprisingly, he got nicknamed Dr Delay Grain.

Note: I was once in AspireSpace before I went over to the dark side and joined MARS, but I had left when this event occurred, honest :-)

All the best,

Richard

You need to install the delay element itself, to complete the forward pressure seal of the motor, but if you don't want the ejection charge fired by the motor, it is possible to peel up the cap and remove the powder.

Gotta love it! : )

No it's not but I suppose adding the epoxy could be interpreted as such. :-)

You mean I have to read the instructions !?!?!?

What kind of hobby is this????

:) Found it right where it should have been, Thanks a bunch!!! Peter

It wasn't just the fact that it happened, it was the swaggering "I, the rocketry guru, who knows all, shall teach you, the rocketry newbie..."
