CCC, Enzo 2 e Dyneema...

Post interessantíssimo do Luc Armant(Projetista e piloto fudidão da Ozone sobre o Enzo 2 e as novas regras de homologação CCC.

About CCC and Enzo2, trying to answer questions. 

- All sizes of Enzo2 (CCC or EN) are direct scaling from the Medium. Line set of diameters are unique for each size, optimized for each maximum weight. Smaller sizes have very small difference in performance compared to bigger ones. 
- On Enzo2, upgrading lines from EN to CCC does not affect performance significantly. For the Enzo2, the only difference from EN to CCC comes from one rule that forbid the use of any lines that would have a braking strength of less than 20daN after 5000 cycles. That excludes the use of the Edelrid 8000U-025 that Ozone use to use on comp wings for top brake lines since 2010. For the CCC we will replace this line by an equivalent line made of dyneema that is not affected in strength by this 5000 cycles. Only the few C lines, where we don't want to use dyneema to not risk a change in trim or camber with time, will be replaced by the 8000U-050. In total, to be precise, the CCC version will have 0.05 points less in glide, which is not significant. 
- Top speed. You can expect about 2 km/h less absolute top speed in calm air between riser with limiters and original riser mounted with full overlap of the pulleys. Note that original risers loose about 1cm distance between their pulleys inner sides after few flights due to the release of some assembly slack (going to about 125mm to about 115mm). In practice, having flew some of the last top level competition with limiters on my risers, I have not even seen much disadvantage. Flying at top speed with limiters is more comfortable and easier (than with overlap) because the force on legs is less and the symmetry is blocked perfectly so that you can easily lock the legs and use B handles (also, new risers will come with much better new B handles).

Além do que ele escreveu... gostaria de chamar a atenção para: 
''..Only the few C lines, where we don't want to use dyneema to not risk a change in trim or camber with time''

Ou seja, pra quem acha que eu estou falando besteira sobre as linhas de Dyneema, está aí... a Ozone também não gosta deste material...Dyneema pode ser até um pouco mais resistente.. mas com o tempo deforma...
