Cesaroni Motor Ignition?

Hi

I have never used a Cesaroni motor before. I have only used small Estes motors.





I have attached pictures of the things I have got in the pack. Please guide me on how to ignite this motor.

You must use an external aluminum case, which is sold separately. Do not attempt to use the motor otherwise.

Also, if this is a CTI 38mm one or two grain motor..read this https://www.pro38.com/pdfs/Bulletin_Pro38_1G_Pellet_Issue_v1.2.pdf

if the above applies to your motor..here is how to cut the pellet. https://www.pro38.com/pdfs/Pro38_Pellet_Modfications_v1.2.pdf

I am confused as to how to ignite the motor? I.e what creates the spark which sets the propellant on fire? How is is electrically connected?

Igniter specifications*:
Bridgewire resistance:
1.2 – 1.8Ω
Rated all-fire current:
1.2 Amps for 10 milliseconds
Typical response:
2.3ms @ 1.2 Amps
(*) These are manufacturer’s specs.

Typically these motors are flown at club launches or by people who have launch systems designed to provide enough current to ignite the electric ignition device that’s packaged with the motor and to do so while maintaining a safe distance.
I would recommend that you find a nearby club and attention one of their launches to see how they operate. Rocket motors are safe when all appropriate safety measures are followed, but can be dangerous if those measures are not followed.
For more information see www.tripoli.org or www.nar.org.

The Cesaroni motors light basically the same way as the Estes motors you've been flying--the igniter just looks a little different. You may also need a launch controller with a little more oomph than what you've been using--anything with a 9V battery or 6 AA-D cells should work.

Adjust the ejection charge delay, load the motor into the casing, load the casing into the rocket. Put the rocket on the rail/rod, slide the igniter all the way up to the top of the motor (you want the tip touching the black pellet at the top), connect the leads of the controller to the ends of the igniter (making sure that neither lead touches the other or anything metal). Go back to the controller and push the button.

Please find a club in your area and go to a club launch to ask your questions. I'm a bit concerned with the questions you are asking; all engines ignite the same way - igniter inserted into the engine, ignition by electrical power, typically 12 volt on high power rockets - it's just the basics. If you haven't done enough research on reloadable HPR engines to know you need a casing and how to do the reloads per the manufacturers instructions, you need guidance from experienced high power rocketeers. HPR is not something you just do, it's dangerous, which is why it is regulated so highly. Be safe.
