Characteristics of Gliders F1A

Surface area (St) ...................................................... 32 - 34 dm2  (496-527 in2)
Minimum weight ........................................................ 410 grams
Maximum length of launching cable loaded by 5 kg..... 50 m

3.5.2. Characteristics of Gliders with Automatic Steering F1E

Maximum surface area (St) ............... 150 dm2  (2,325 in2)

3.K.2. Characteristics of F1K

Minimum weight (without CO2) .........75 g
Maximum surface area (St)..............12 dm2  (186 in2)
Maximum volume of the CO2 tank(s) 2 cm3 (connecting tubes count only if their outer diam. is over 2mm).
