Hi Mathew
I cannot help with the Discus 2cx designation, if there is such an animal?
But the V2 and V2CX have identical fuselages and crash protection.
They are different from the V1a,b,c with a 5" wheel, larger cockpit
and better side to side vision for tall pilots. V2CX has new fin,
rudder and stab, as well as 18m tips with new planform, less
dihedral, new airfoil, flaperons that extend to the tip, and winglets.
MTOW is 600kg vs the 525KG of the V2. Handling is superb in
either and much better than the V1a,b,c. Noticeable high speed
performance advantage with the 2CX over the 2C.
