New Plan -- Whippit
Here's an example of what we could be doing in the area of two-stage models once we get the booster motors. This design is tweaked for 10mm motors.
Length: 23.45"
Diameter: 0.908" (ST-8)
Fin Span: 4.41"
Weight: 1.105 oz
A8-0 | 1/2A6-5......430'......Dv 25 FPS
A10-0 | A8-5........700'......Dv 2 FPS
A8-0 | A10-5........724'......Dv 12 FPS
A10-0 | A10-4.......750'......Dv 22 FPS
A8-0 | A3-5.........755'......Dv 5 FPS
A10-0 | A3-5........780'......Dv 5 FPS
The model qualifies as a "Schoolyard Sounder" by using motors 13mm or smaller [I may allow 15mm motors here, but not just yet.] All motor combinations reach flight velocity on a 36" standard rod.
Enjoy!
