Exclamation New Design -- Alpha Probe

Another design with transitions-a-plenty...

I think it has some pleasing lines, and the performance numbers are spectacular. Very low Dv on C6 and B6 power.

Length: 28.03"
Diameter: 1.64" (Transition #2)
Fin Span: 5.04"
Weight: 1.93 oz


B6-4......350'......Dv 7 FPS
C6-5......828'......Dv 6 FPS


Patterns shortly...

Both engines reach safe flight V on a 36" x 1/8" rod.

Share and Enjoy!

Exclamation

...And the patterns...

One 5" x 9" cardstock sheet with the three transitions.

One 2" x 9.6" x 3/32" balsa sheet with the main fins.

One 2" x 6" x 0.05" matteboard sheet with the cooling fins.

One 1" x 3" x 1/8" balsa sheet with the LL standoff. Same one used in the Hi-Five.
