(ROL Newswire) -- AeroTech is re-releasing its 18mm D21T single-use
model rocket motors, which have not been manufactured since October
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
A copy of the D21T instructions (including a thrust curve and other
motor data) in PDF format may be downloaded from the AeroTech Resource
