Ok people I think I'm back into the hobby after leaving in 2000. I have 38mm, 54mm and 98mm of all sizes for AT. After reading this whole stream I'm assuming reloads are available and still the same. Not to age me, but im staring at my LEUP license right now...Wow Allot has changed. It was a life changer just getting that back in they day and having ATF visit me once a year. Any of you guys remember that?
YesI have an aerotech 54/2560 case and a plugged threaded forward closure. If I had bought a smaller casing, lets say the 54/1280 casing, which the reloads have ejection charges. If a reload i was using had an ejection charge, would i be able to just ommit the ejection charge and use the plugged threaded forward closure instead?
You can use the plugged closure. There is just no place to put the black powder. You still use the delay grain, now called a smoke grain. Assemble the motor per the instructions with the reload kit.I have an aerotech 54/2560 case and a plugged threaded forward closure.

The chances of a blow by when using an open bulkhead are far higher than an altimeter failure. Use a plugged closure even if flying only one altimeter once you are very confident in your altimeter prep.You may want to consider using the ejection charge anyway if your rocket design allows (along with a non-plugged fwd closure), as a backup to your altimeter-fired ejection, assuming it’s not redundant already.
Not to belabor the point, but I've experienced one incident of both of these failure modes over the years. The consequence of my Loki K-1127 burning through the forward bulkhead was the premature deployment of the recovery system. All pieces returned softly under chute or tumbled harmlessly to earth. The single-altimeter failure, on the other hand--a loose battery cable losing continuity to the Stratologger in flight--would've caused a ballistic return of the whole enchilada if not for the motor-initiated ejection back-up--a bit more potentially consequential event. Redundancy is the best approach, in my view, and in fact is mandatory for a Level 3 design.The chances of a blow by when using an open bulkhead are far higher than an altimeter failure.

It’s good malfunction mitigation. I drilled the delay to pop 2-4 seconds after the sim-calculated apogee time to reduce likelihood of a simultaneous ejection firing. This practice saved me from a lawn dart once when a wire loosened from my single Stratologger, causing the primary ejection means to fail.
Good skies,

The COVID-19 situation has seriously disrupted the beginning of the 2020 Launch Season... Your friends at AeroTech/Quest/RCS are continuing to produce starter sets, rocket kits and composite propellant rocket motors. We're fulfilling and shipping orders as complete and as fast as possible.
They have not
Is there already information about when the next delivery can be shipped to Europe?
Can't help you with Rocksim... but I did create a couple of .ork files for it... The shorter early production of the kit (with a 27" booster tube) and the current production with the longer 28" booster tube.Hello Charlie I'm just wondering if you would happen to know where I can find a Rocksim file for the mega initator?
thanks for your time

Are you referring to the forward insulator or something else?So how important is that thrust washer in a G79 29mm loadable Aerotech Motor? It fell out of the casing while I was epoxying and didn't notice until it was too late...
Sorry, Forward insulator is correct. Fly without or in the garbage?
It will be, the forward insulator if not present will turn the motor into a road flare after it blows the forward closure out. Contact Aerotech and have them send you a new insulator for that reload.It might be a $25 learning experience...
