I love AT endburners! They are the motors that my Vulcan glider likes to fly on more than any other reload.
Nominally, I49 and I59 require a special "endburn-style plugged threaded" closure. It's a solid piece of aluminum without a delay grain cavity; the reload kits come without delay grains. With an endburner, tha danger is that flame front can get around the grain and if you burn the candle from both ends, you're likely to overpressure the case. Pressure above the grain can also try to push the grain down through the nozzle, which may plug the nozzle and again result in a burst casing. AT's 1-grain endburner (G69N) comes with a smoke grain and uses a normal plugged closure, but instructions tell you to inhibit the top of the grain with epoxy and the delay grain with lubricant. Apparently, for the larger endburners, AT feels that this precaution is insufficient and tells you to buy the special closure.
