Hi Ken,

With all respect for my late friend Wally Gitchel, his design for a R/C skydiver was not the basis for the Paramax design. A guy named Jurgen Vollmann designed the Parafoil canopies and jumper bodies in Germany in the middle 80's. The rights to this design were sold to the Krauss' who still make Paramax products. Also prior to Wally's interest in R/C skydivers, the Robbe Charly was available and was used here locally. The Charly operates the control arms directly from the servo output shaft. As pointed out, this can lead to stripped servo gears and it's probably best to use metal gear servos.
