AeroTech Demonstrates 18mm RMS-R/C™ Reloads at NARAM-55
AeroTech unveiled two new 18mm RMS-R/C rocket motor reload kits at the National Association of Rocketry (NAR) NARAM-55 launch near Aurora, OH.
The C3.4T-P and the D2.3T-P reloads are “plugged” and intended only for use in radio controlled rocket gliders and cars. They do not include a delay or ejection charge and are therefore not suitable for standard vertical launch model rockets, without the use of electronic recovery system deployment.
The motors were successfully demonstrated in several flights by Zachary Stenberg and Keith Vineyard at NARAM on Friday 7/26 in their FAI class S8D R/C rocket gliders.
Instead of using R/C-specific hardware like previous RMS-R/C motors, AeroTech designed the new end-burning reloads to be compatible with existing RMS-18/20 hardware. Users are instructed to plug the ejection well in the forward closure with “JB Weld” epoxy to prevent reverse thrust from escaping out the forward end of the motor as the propellant grain burns out. AeroTech will make a separate forward closure available for users who wish to continue using their RMS-18/20 motors with standard model rockets, and there are also plans for a “plugged” forward closure to eliminate the step of applying the JB Weld epoxy.
Both motors are NAR certified and have an initial thrust spike of approximately 2 pounds that quickly drops to about ½ pound during the sustain portion of the burn, tapering to 0.4 pounds at burnout with the D2.3T-P. The C3.4T-P has a burn time of 2.9 seconds while the D2.3T-P has a burn time of 8.6 seconds.http://www.nar.org/SandT/releases/R142.html
The C3.4T-P and D2.3T-P reloads may be purchased by flyers 18 years of age or older, with no user certification required. The reloads are available now from the ValueRockets.com website at $12.99 per 3-pack for the C3.4T-P and $14.99 per 3-pack for the D2.3T-P. A bulk pack of 12 reloads will be available soon at a price 10% lower per reload than the 3-pack price.
The 18mm RMS-R/C reloads ship with the new FirstFire Mini™ 2-wire igniter due to the extremely small throat size. Ignition with the new igniters is easy, quick and reliable.
Instructions and NAR certification documents for the 18mm RMS-R/C reloads are now available for download in PDF format from the Resource Library on the AeroTech website at http://www.aerotech-rocketry.com/.
