High-Power Motor Purchase Requirements
The sale of 'G' motors and larger and all model and high power RMS reload kits to persons under 18 years of age is currently prohibited by federal law. Individuals must be 18 years of age to purchase high power hardware. Proof of age (such as a copy of a driver's license) must accompany all orders for 'G' and larger motors and all RMS reload kits. The consumer must be a current member in either the National Association of Rocketry or Tripoli Rocketry Association and be certified Level 1 (H,I), or Level 2 (J,K,L), or Level 3 (M,N,O) high power user, 18 years of age or older to purchase all high power reload kits.
Please note that orders requiring additional documentation cannot be shipped without a copy of a NAR or Tripoli Rocketry Association Level Certification card, or evidence (business license or purchase order on company or school letterhead) that you are a legitimate business or academic customer.

Description
For adjusting AeroTech 54mm RMS-Plus delay elements.
The 54mm RMS Delay Drilling Tool™ (or 54RDDT, P/N T082510-2) is designed for shortening RMS delay elements to adjust the time delay of a 54mm AeroTech RMS reloadable motor. The 54RDDT consists of a machined drill tool body and a 1/4” stub drill bit with an attached knob. The tool also has a provision for calibration, as the tip of the drill bit must be flush with the end of the tool body for accurate use. Though adjusted initially at the factory, a set screw placed within the knob makes any necessary readjustment easy.
The ends of the tool are counterbored with recesses that are labeled with 4 or 8 second reductions in the delay time. To use, the RMS or RMS-Plus delay element is placed into the desired end of the tool and held firmly in place, the drill bit is inserted and the knob is rotated clockwise until the bit is fully seated in the delay and no resistance is felt. In addition, a supplied 1/16” thick washer may be placed between the drill tool body and the drill knob to shorten the delay to an intermediate value.
As is always the case with drilled RMS delays, the delay element should be installed in the motor with the drilled end facing the propellant grains (or away from the ejection charge) for best delay accuracy. Also, no delay should be shortened to less than 4 seconds.
AeroTech is planning to eventually sell most RMS reloads in only the longest certified delay, so the RMS Delay Drilling Tool will be essential for the future use of the RMS line of products.
