North Wing ATF Soaring Trike
ATF Trike ATF and Solairus Wing

The ATF Trike can be used with your hang glider, but the best performance across all flight conditions will be achieved with our new Solairus lightweight trike wing.

The new strutted Solairus is a double-surface wing with a state-of-the-art airfoil, and is great for cross-country flying, short-field take-offs, and has excellent handling.

The ATF Soaring Trike (ATF = Air Time Fix) adds power to your hang glider so you can climb to the thermals and power-off for lightweight trike soaring!  You can use your hang glider with the ATF Trike, or use our specially-designed Solairus wing which has been built specifically for lightweight trikes, with a state-of-the-art airfoil design.  The new strutted, double surface Solairus wing provides best performance for cross-country, has a great sink rate and slow-speed handling, and is best for short-field take-offs.  No mountain, no problem!

Imagine! Ascend effortlessly up to cloudbase.  Shut the engine off and soar in silence with the birds all afternoon.  When the lift gets light, pull the overhead starter and fly back to your flying field.
