Redesigned J1999N-P Certified by TMT
The J1999N-P reload for the RMS-54/1280 motor hardware has been redesigned by AeroTech and certified by Tripoli Motor Testing (TMT) as the J1799N-P.
The J1799N-P replaces the J1999N-P that was decertified by TMT and withdrawn from sale after a number of failures were experienced by consumers during LDRS-29. The J1799N-P delivers a total impulse of 1066 N-sec over a burn time of 0.60 seconds with a peak thrust of over 476 pounds.

AeroTech has produced a "repair kit" that consumers possessing unfired J1999N-P reloads manufactured prior to July 2010 will be able to obtain at no cost through any authorized AeroTech high-power dealer. This kit includes three replacement propellant grains, a new nozzle, grain spacer o-rings and revised instructions. Customers are requested to return their unfired J1999N-P nozzle(s) and instructions to their dealer to receive the repair kit.
The complete J1799N-P reload kit will be available for purchase from AeroTech’s dealers at a suggested retail price of $119.99 each. AeroTech anticipates shipments to its dealers to begin in approximately 2 weeks. The J1799N-P is being submitted to the California Office of the State Fire Marshal (OSFM) for approval of sale & use in California.
Motor instructions and an assembly drawing for the J1799N-P are now available for download in PDF format from the AeroTech Resource Library at http://www.aerotech-rocketry.com.
