Wing options for the Snake
Due to the extremely light weight of the Snake trike we can offer all of the wings listed below and still remain within the SPHG 70kg weight limit with full fuel. The Snake is the only trike available in the UK offering double-surface wings within the 70kg limit.
If you are planning to operate the Snake as an SSDR microlight there is an even greater range of wing options available; please contact us for details. These include competition-level soaring wings and high-speed touring options.

The 3DC is a 13.5m² double-surface nanolight wing. Double-surface wings offer improved efficiency compared to single-surface wings due to enclosing the cross-tubes within the wing. The 3DC provides superb handling and performance and was the choice for David Broom’s attempt at the world record for distance without engine power.
The 3DC is generally tuned for around a 35mph cruise speed. The stall speed is in the region of 17-20mph depending on weight and if the optional vortex generators are installed (which also have the effect of making the stall even more gentle and benign than standard).
The wing handling is wonderfully light and sporty at all speeds, and offers predictable behaviour for short field operation. MTOW is 190kg with a wing weight of around 29kg.
New for 2018 is the Grif Zip. This wing carries just enough double-surface to enclose the cross-tubes, and sits somewhere between the 3DC and Aeros Fox wings in terms of performance and price. It weighs only 28kg and yet still carries the 190kg (tested at +6G) MTOW of the Grif range.
All Grif wings offer various ways to reduce the packaged length (useful if storage space is at a premium, or for transporting the wing on airlines). The quick short-pack reduces the packed length of the 3DC from 5.32m to 4.58m. A further reduction is possible to only 3.57m length. Neither of these short-pack options require any tools and can be completed in minutes.
A PX20 trilaminate leading edge is available as an option, as are a range of undersurface colour combinations. Grif can also powder-coat the A-frame and kingpost any RAL colour in order to create your ideal colour scheme.
Another option is a LED strobe system built into streamlined fibreglass wingtip fairings. These are ideal for improving visibility in low-light conditions as well as improving the aesthetics further.
Grif also offer the HX11 & HX12 wings for higher touring speeds (50-60mph), suitable for those with a microlight qualification.
Our most affordable wing option is the Aeros Fox13T single-surface wing, specifically designed for nanolight sub-70kg aircraft. The excellent stability and docile handling make this a perfect wing for beginners. It’s the lightest wing we offer, at 25.5kg with the optional ODL Technora wing fabric. A range of Dacron colours are available as a no-cost option.
A wing-fold kit can be incorporated into this kingposted wing if trailering the Snake is preferred. This can reduce the rigging time to around 5 minutes.
Hands-off cruise speeds are in the region of 30mph, with a 21mph extremely gentle mush stall. The wing is perfectly capable of extended engine-off soaring, although the sink rate increases dramatically at higher speeds. This characteristic makes the Fox13T an ideal choice for short-field operation, particularly as the light weight makes fitment of the 33Hp Bull Max engine possible under the 70kg SPHG limit. Maximum Take-Off Weight is 170kg.
The Snake is also compatible with the entire range of Aeros nanolight wings (including the impressive Combat), although all of these are too heavy for sub-70kg operation with a full 10litre fuel tank.
Fly & Rio
Ideal for hang-glider pilots who desire one wing to both free-fly and operate with a nanotrike, the Avian Fly (single-surface) and Rio2 (double-surface) wings are now available with the Snake. A detachable hang-bracket allows the wing (available in both 15m² and 17m² versions) to be quickly converted from trike use to free-flight harness in supine configuration.
The handling and performance of the wing is little affected by the addition of the trike unit, and the takeoff and landing performance with the relatively low stall speed is truly spectacular!
The variable geometry option allows in-flight adjustment of sail tension, and laminate sailcloth options are available for the Rio only.
