Purchasing a used paraglider.

By this point, you've gotten a sense that I am very much in favour of finding the most cost effective means possible to get and remain in paragliding (and still retain a high degree of safety).

I've outlined how you can go about evaluating your local schools to find the true 'soup to nuts' cost of getting a license with Paragliding Economics 102: Lessons.

I've also outlined why with your first wing you should favour a used paraglider over new and rental over used with Paragliding Economics 101: First Wing Purchase.

But lets say your local school does not offer wing rental? Now what? Assuming suitability (as discussed with your instructor) and availability, into the 'pre-owned' bazaar we venture.

Two Simple Rules

Rule 1: The seller needs my money more than I need their wing. 

This is my variant of the age old 'there is no such thing as savers remorse'. I remind myself of this before any interaction with someone looking to sell. Putting myself in this frame of mind helps keep me objective and enables me to easily walk away - a deal that fails leaves me with money everyone wants and the seller with a wing few people want.

Rule 2: Trust no data that is not readily measurable. 

Launched off grass, accordion packed, no SIV, closet stored. None of these statements mean anything to me as I can't readily verify them. As a buyer I want to know four things - the 'Four Ps' - price, pilot, pics and porosity.

The Four Ps

Price - Price is self explanatory.

Pilot - I want to know who has been flying this wing. This info allows me look up the flight logs in Leonardo and XContest. I can also look up videos on YouTube and Vimeo. I can even look the pilot up in ParaglidingForum.com. Sounds creepy? I don't think so. This is how I determine if they are being honest with me - compare the description of the wing with their digital paragliding foot print. I have seen cases where a pilot selling a wing claimed it had only X hours but was bragging a month earlier on Paragliding Forum how they had clocked 2 times X on the wing that summer. Likewise with track logs and videos. Only grass launched, how about those tracks in Turkey? No SIV, funny that video of acro over Annecy. If there is any inconsistency, remember Rule #1 and walk away.

Pics - Pictures of the wing are always nice, but what I am after is a pic of the manufacturer label. This will have the Make, Model, EN rating, Serial Number (S/N) and Date of Manufacture (DOM). With the DOM I apply my previously suggested depreciation of 20% per year and check it against the sale price. Also, if there is any doubt in the legitimacy of the sale, I ask that a sticky note be placed in the photo of the manufacturer label with my name and date. I would reserve the use of the sticky to be a condition of final sale after price is finalized and not something to push for right away.

Porosity - I will not touch a used wing that has not had a proper test done by a porosity meter. I would also ask for a photo of the test result.  My minimum is leading and trailing edge centre top cell - it is the part most likely to be smacked nose first into the ground on landing and dragged tail last during take off. I suggest researching the relationship of porosity to wing lifespan, there are a few graphs floating about. One note of caution - a wing can retain porosity well after the fabric has passed its useful life - you will frequently see this with wings from the last decade flown only one season and closet dumped. The porosity will be high, but the fabric will have the strength of tissue paper. Another reason to ask for a pic of the manufacturer label. I personally will not consider a wing more than a few years old because of this.

Summing it up

With a little 'leg work' and an objective mind, there is quite a bit of savings to be had by going into the secondary paraglider market rather than purchasing new outright. If you keep the Two Rules and Four Ps in your kit while evaluating options, you stand a much better chance of walking away with a deal you are happy with as opposed to an unexpected surprise a season or so down the road.
