A PPL has\u00a0the advantage over RC skydivers\u00a0that it can\u00a0take off\u00a0by\u00a0ifself and act like a parachute on the way down. No need for a RC plane to carry it to the desired height thus very flexible to use. Coincidently I discovered that one of the\u00a0experts on the web, which takes these PPLs&#8217; to the next level, lives in The Netherlands. FK of <a href=\"http:\/\/www.aircatcher.com\/\">aircatcher.com<\/a>\u00a0was kind enough to demonstrate his PPL and offered his specialist services for this project.

Pros: chutes are simple in design and construction, thus more safe to be deployed under drogue. Cons: lower glide ratio, aroud 3.
