Did anyone run across any information related to Wingtips
design/availability for the PW-5. This is understood that it will negate
PW-5 World Class categorization however shell be available to all PW-5
registered uder Experimental Cert...
The only PW5's I've met in person felt so lightly built that I'd be a
bit worried about whether there is enough margin for increasing the
root bending moment as you would with span extensions. Of course,
there might be enough margin for some modestly-sized winglets but even
those will increase the root bending moment somewhat.

**** .. In a matter of fact, PW-5 is built in the "tradition" of other polish glass gliders ( Jantar, Acro etc ...) ... strong and over-engineered at best - LIKE TANK ... don't be fool by the light "feeling". I personally know a privately owned PW-5 which is loaded to the "brink" by its owner in order to get higher wing load for XC .. and it works rather well for him ..
Also, there are some tips that there were 15m PW-5 version with a retrac gear on their desks (politechnika Warszawska) ... but it never took shape since it did not comply with World Standard .. and SZD had Junior in prototype stage already ..
Anyway, in my opinion 0.7 meter wing extension with winglet would be a really nice performance enhancement for this ship. Make it swappable with original tips and you really would have a great XC trainer.
As for me ... I love it..
I am 6'4" ... and feel REALLY COMFORTABLE in PW-5 cabin ... being 210lb myself I use 4kg tail ballast for CG adjustment. In XC flight it beats anything but the modest glass costing few times over ;-) ...
