AeroTech Consumer Aerospace has redesigned its five single-grain 54mm “soda can” motor reload kits to use less expensive components and has significantly reduced prices on the entire range of reloads for the Reloadable Motor System™ (RMS™) 54/426 hardware.
The modifications, which include the substitution of a lower-cost liner and a smaller nozzle insert (the same as those used on the 29 & 38mm RMS reload kits), have been reviewed and approved by the Tripoli Motor Testing (TMT) Committee of the Tripoli Rocketry Association (TRA). The nozzle throat areas are identical to the previous versions and the ballistic performances of the new loads remain unchanged within statistical variation.
Suggested retail prices for the I115W (P/N 09115M), I229T (P/N 09229M), I117FJ (P/N 09117M) and I215R (P/N 09215M) reload kits have been reduced from $49.99 to $39.99 each, in line with the prices for AeroTech’s 38mm reloads of comparable power. The retail price for the I599N Warp-9™ reload kit (P/N 09599P) has been reduced from $59.99 to $49.99 each.
The redesigned reload kits require use of the new 54mm small nozzle aft closure, P/N 54ACCSN, which was previously released in October 2009 following announcement of the J99N-P endburning reload for the 54/852 RMS motor hardware. The 54mm small nozzle aft closure retails for $39.99.
AeroTech is currently looking at the feasibility of using the smaller nozzle design with additional reload kits for the RMS-54/852 motor as a means to reduce prices on the J275W, J460T and possibly other reloads.
In related news, AeroTech is working on a sixth reload kit for the 54/426 motor using its popular Mojave Green™ propellant, for release in the Spring.
Motor instructions and assembly drawings for the redesigned reloads are now available for download in PDF format from the AeroTech Resource Library.
