Small moonburners and igniters

[Brian H.]

I did a search and found lots of answers for larger moonburner motors, but nothing for the small ones. I have recently had a Cesaroni H54 29mm moonburner Cato because the igniter wadded up and clogged the nozzle. Is there a trick to preventing this from happening?

Others use bamboo skewers, zip ties, and such for larger motors, but I don't see that working very well on a very small nozzle in a 29mm.

What did you use for an igniter?
Supplied one with motor or your own?

 

[Brian H.]

The one that came with the motor. It was a standard CTI chip style with shooter wire leads.

I don't think the ignitor was the issue..

Upon inspection after the Cato, the igniter was sort of in a pile in the nozzle. What else do you think it could have been?

Bad reload. I have warrantied a couple of that motor already

Would I go through the vendor I bought it from or contact cesaroni directly? I have only dealt with Estes catos in the past.

I should fill out a mess report also. I just figured it was the way I installed the igniter.

Go to the vendor. They should take care of the warranty on the reload and hardware if it was damaged. If your vendor won't, then send me a pm and I'll get it taken care of.

Thank you. I got it from Apogee. I don't think Tim will have any problems. They have wonderful customer service and are within driving distance.

It did destoy the case. Blew the forward closure and fuel grain up through a plywood bulkhead into my ebay and sent the upper half of the rocket about 10' up. Fortunately my electronics survived.

Nice catch CHRIS.....problem solved!

So I contacted Apogee and it looks like it could be a considerable amount of time before I could get anything replaced. Need to fill out a form and mail or email to them along with pictures, they contact Cesaroni, Cesaroni sends a replacement to them on next shipment if warranty approved (which could be awhile as they just received a shipment), then I get a replacement sometime later.

Is this a normal procedure?

It is up to the vendor to either replace from stock or wait for the replacement from the manufacturer. I usually replace from stock if I have enough...but I haven't received the returns from the manufacturer in several years(despite getting orders) so I've considered using the other method as well.

 

[Brian H.]

Thanks for the info. I didn't consider issues with the manufacturer actually replacing the defective item. That puts a huge strain on vendors that do replace fom stock.
