Parajet can help getting a good price on the shipping if you send them as a group. The price will depend on the number of you who want to use this and how heavy your machines are.
You need to pack your machine yourself for customs and get it to Parajet for Thursday 24th of September. This leaves lots of room for customs to slow things downs. It will be sent with UPS and it takes about 5 days in transit.
Make sure you attach a clearly visible sheet of paper well stuck down (preferably in something waterproof) on the box with Icarus Trophy and Your name written down.
Based on 2 pallets taking 200kg each (about 5 paramotors) UPS have given a quote of £3,000 return. Which could be as little as £300 return per paramotor based on 10 machines going.
If you need packing material and a box, Parajet can sell them to you at cost. £50 for a V3 and £35 for a Zenith
If you just want to ship it back but will be flying in with it in the hold...
At the finish line those nice people at BlackHawk Paramotors will have packaging and boxes on hand at cost price. Customs rules mean that you must package your kit up yourself. BlackHawk will then organise getting your precious kit shipped back home.
A 'ball-park' figure for this is around $400 (plus packaging materials)- but this obviously depends on where you are shipping to..
