New Design -- GSS Horizon
Jay's latest design "Argent" must have struck a chord... 
The GSS Horizon follows the same basic pattern, but is smaller and capable of very good performance on the 13mm engines.
Length: 20.90"
Diameter: 1.04" (ST-10)
Fin Span: 5.02"
Weight: 1.24 oz
1/2 A3-2T......98'.......Dv 8 FPS.......36" x 1/8" rod
A10-3T.........306'......Dv 21 FPS......36" x 1/8" rod
A3-4T..........310.......Dv 12 FPS......48" x 3/16" rod
Note carefully the A3-4T line. The model has a very slow acceleration off the rod, and needs a full 40" to reach safe flight V. The A10-3T reaches flight V in 20".
Enjoy!
