AeroTech Re-releases D21T Single-Use Motors July 20, 2005 Web posted at: 5:37 PM EDT
(ROL Newswire) -- AeroTech is re-releasing its 18mm D21T single-use model rocket motors, which have not been manufactured since October
2001.These motors are the same physical size (diameter and length) as a black powder 'C' motor, but produce over twice the total impulse. The D21T also delivers more power than a black powder 'D' motor in a much smaller and lighter form factor. They are perfect for rockets of lightweight construction as well as oversize models that need more impulse than a 'C' motor can provide.
The D21T will be available in 4 and 7 second delays.
The D21T is defined as a "model rocket motor" and while no user certification is required, they are recommended for consumers 16 years of age or older.
The D21T can be shipped via U.S. Postal Service Parcel Post with no hazmat fee, due to the fact that the motor contains less than 30 grams of propellant.
A copy of the D21T instructions (including a thrust curve and other motor data) in PDF format may be downloaded from the AeroTech Resource Library at
