yeah, U're right, they're making profit with the cards. at least the jamara, which is w/out card, is cheaper. I've contacted graupner via their forum on
www.gm-racing.de, which is usually the best way. In an other forum someone said that they are going to put the manual on the (Jamara?) web-page.
but when... it took me already 2 months to get the esc. the first one (version 1) just didn't work on 5 or 6s. summer passed by... I was so pissed-off.
