Today I discovered an issue with my flight yesterday at Airfest. Everything seemed fine with the flight so I thought it was a success. I had dual deploy and today discovered the drogue ematch did not ignite the powder in the charge well. I did not have the ematch buried in powder but it was on...

Yesterday after flying my K560 at Airfest, the smoke plug plastic piece doesn’t want to come loose out of the 75mm AT adapter system top floating closure. I took the engine apart while still warm but not as soon as sometimes. Should have I used more grease in the top floating closure and how do...

Hello. Yesterday I loaded up an AT K560 into the phenolic liner and the propellant fits very tightly into the liner. It took me pressing my hand down with substantial weight to get both propellents to slide into the liner even after sanding the edge of the cardboard a bit. The further in they...

I am wondering how far ahead of a scheduled launch is it OK to put your reloads together for your motors? I know aerotech recommends not opening the road kit until ready for it, but it is nice to do it ahead of the launch if possible for myself. Is the main thing to keep them dry so they don’t...

Hello. Asking for a friend, who is attempting to build a rocket and sugar motor following Dan Pollinos book, ‘I Still Have All My Fingers’. They aren’t able to find the templates on the website his book says is provided to build the nozzle and parts of the rocket. The website is...

Good evening. I have launched my 5.5” diameter Loc Big Nuke one or two times without having protectors around my nylon shock cords. I am wondering if the ejection charge gasses pose a threat to them becoming brittle and breaking beings they were unprotected? I am wondering if I should purchase...

Would someone have the RS files for these two 6” diameter fiberglass rockets? If so, would you mind sharing? Thanks in advance

I seem to have misplaced my engine retainer and am looking to replace it if somebody has an extra

Hello. I have a 5 1/2 inch Loc AvBay that I use on my Big Nuke rocket. When I built it I was not thinking of using it on future models of larger diameters. I have been interested in building a 7 1/2 inch Loc kit and wondering if there is are some good suggestions on how I can mount my sled in a...

Hello. It’s been several months since I reloaded my previous AT L850 motor but I was pretty sure it had the Medusa nozzle and now I put one together today and it has the single throat nozzle. Has AT recently changed that or is this a mistake and I have the wrong nozzle with my reload kit...

Hello. I purchased these igniters as a back up and I am wondering if they will ignite in L850 AT motor as they do not have as much powder on the ends? Would you recommend I beef them up somehow?

Hello. I have flown L2 with duel altimeters up to the AT L850 motor. I missed doing a new build last winter and am thinking ahead to a possible build this winter. I am interested in something that will fly possibly on an M or maybe just a baby M if so desired but that I can still stick to K...

Merry Christmas. I have built a few HPR kits in the past and modified a fiberglass kit I purchased used. They are large and fly fairly slow. I have a few questions about fiberglassing as I have never done that for possible future kits I may purchase. How do know when it is necessary to...

Wanting a simple non subscription gps tracker besides the Marco Polo for my rockets. Anyone know of any? There are a ton of GPS car trackers, but most of them require a monthly subscription.

Good evening. I recently flew my Loc Big Nuke 3E at Airfest 27. With an AT L850 it had a projected altitude on RS of over 9,000 feet. However, both altimeters only recorded 6,400 and some feet. They were within 40 feet of each other. I am wondering why RS was so far off on the predicted...

Hello. After launching my first 75 mm L850 at Airfest the other week, it had a large hole through the liner on one end (please see attached photo). Is this normal, or was there a near Cato?
