Tempest DS
Looking for a little extreme DS action?  Then the Tempest DS is the plane for you.  From the outside, it may look like a standard version of the Tempest, but, as they say, it's what's on the inside that counts. 

Construction features:

High modulus carbon spar caps
A combination of bias fiberglass and carbon wing skins
Laminated fiberglass, VG balsa, and plywood shear webs
Multiple sub-ribs throughout wing, V-tail, and control surfaces for torsional stability
Dual carbon joiners on both wing and V-tail
