Estes EST9720
Doorknob Scale Pro Series Rocket Kit
Standing over 27 inch tall with wood fins and
powered by E and F engines the Doorknob can
reach the maximum altitudes of 1100 ft. on an
F15-6 Estes engine. The 18 inch nylon parachute
creates a long, smooth recovery. An easier build
than other pro series kits, the Doorknob is a great
introduction to rocketeers looking to increase their
building skills and practice using higher powered
engines. As a bonus, this kit has two sets of decals
available for those who want to turn this scale
model into a sports model.
