    Post Mortem on L2 CATO

    Hi all, I just got back from attempting my TRA L2 certification flight. I reused a previously built Apogee Zephyr with motor ejected parachute recovery that I used for my L1 certification and have flown with AeroTech H100 and I284. I attempted my flight with a J340M-14A with a 12-second...

    G138 Cato Destroyed my rocket.

    I know it happens, but this particularly bummed me out. Built a LaserLoc 163, modified it for dual deploy with a nice ebay and added GPS tracking in the nosecone. Finished it nicely and was ready for its maiden launch this past weekend. Before I tried it on a 38 mm motor I wanted to just make...

    Estes E-12-9 CATO

    Saturday morning, a beautiful Michigan morning, a good friend of mine loaded 2 Estes E-12-9 motors in to his rocket, I have witnessed fly several times with great flights. On this instance both engimes lit and at aprox. 1/2 way up the rod, the rocket experienced a rapid disassembly. The bottom...

    CTI i303 blue CATOs

    Anyone having issues with the CTI i303? Had a guy I fly with CATO two of them using different cases. First one looked like a hard chuff. It wasn't until he brought the airframe back that we saw the aft closure blew out and the case shot into the av bay and did some good damage. The second one...

    Estes A10-3T - 2 CATOs Batch# B180619

    I went to a club launch today (CMASS launch in Acton), and it was a real CATO-fest today. Not sure what's up with that ... really moderate weather conditions. Personally, I had two A10-3T motors CATO - one model destroyed (Semroc Gyroc - RIP), the other model survived. The first CATO blew out...

    I recently launched an HPR rocket and it barely made it off the launch rail after experiencing some sort of engine difficulty. The staff at the launch site said the failure was caused by a bulkhead that failed and allowed the engine to go through the vehicle's body but I'm not sure that I fully...

    Small moonburners and igniters

    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...

    Motor reloads with the most CATOs

    After so many years with no CATOs, I experienced my first one on a CTI K300-P Classic motor on the maiden flight of a new rocket on a 10,000 foot altitude attempt. If you have had a CATO, you know that horrible feeling of loss after spending so much time and money planning, building and perhaps...
