30.4.2023. Photon vs Delta 4 glide

Small speed and glide comparison between Ozone Delta 4 and Ozone Photon gliders. There are two Photon gliders on the video, one is blue and other is yellow. Delta 4 is L size loaded with 114kg, Photons are ML size loaded approximately 7kg below top. Yellow Photon started glide much before with 200m less high and engaged 30% of speed bar. Delta 4 used almost full bar(impossible to use full bar on Delta 4 with Woody Walley GTO harness because not enough length until speed hooks hits harness rings) while blue Photon pilot using 80-100% bar to match speed with Delta. When he pushed full bar (1:23) Photon is faster by small margin but with larger sink rate. Delta 4 still has some juice to offer. After Photon pilot aborted bar usage Delta 4 continue with 2/3 of speed bar.

I'm impressed. That Delta 4 is an awesome design. What are the yellow crops in the valley? Looks like they might be in bloom?

Ovo zavisi od mnogo faktora,novi Foton po svim rezultatima je napredniji od Delte 4 ,jos ovaj na Deltu zategnuo spid.Ima nekoliko videa gdje se uporedjuje brzina Delte i Photon-a preko trim i speed-a ,Photon je primetno naprednije krilo na svim poljima.

Slažem se da je napredniji ali ta razlika izgleda nije toliko ogromna kao što se misli
