Exclamation New Plans -- Whippit and Whippit-X

Schoolyard Sounders.

These are two-stage designs for 13mm motors. The design is inspired by the old Estes Farside and Estes Delta models; they are not simple reductions of those designs. Both of these models will provide reasonably good small-field action, gaining less than 700'.

Whippit:

Length: 22.45"
Diameter: 0.908" (ST-8)
Fin Span: 4.41"
Weight: 1.38 oz

A10-0T / 1/2A3-4T......446'......Dv 6 FPS
A10-0T / A3-4T.........695'......Dv 27 FPS


Whippit-X:

Length: 20.75"
Diameter: 1.04 (ST-10)
Fin Span: 4.41"
Weight: 1.41 oz

A10-0T / 1/2A3-4T......437'......Dv 6 FPS
A10-0T / A3-4T.........683'......Dv 25 FPS

All motor combinations reach safe flight velocity on a standard launch rod.

Enjoy!
