Axis Sirius Tandem wing This is the best Tandem wing I have flown yet and been a commercial operator who flies between 300-500 flights a year you need a wing that is versatile and meets the demands of safety and performance . What I like about the Axis Sirius is the wing has very good handling and speed which is nice for our coastal conditions with strong wind launches . Its also a a massive performer in thermal flying and likes the weight range to be more the top of the weight range as it performs better there with good speed and glide . The glider handling is great and one gets good feedback and turns easy and with precision . The new trim system is a dream and gives you extra speed what feels like a turbo when releasing the trim tabs for maximum speed . The Tandem enjoys some high energy stuff and wingovers and spirals are easy to enter and with relatively easy exits . What surprised me was this wing with a smaller that normal wing are of just over 40 sqm is really good in light lift and can stay up in small and broken lift as good as a single wing . If you buy this wing you can go wrong as it gets a thumbs up in all departments .
