The Quantum 2 model was created in collaboration with Dirk Pflug and Pierre RondellAccording to Dirk, the objective was not to replace the Quantum 1, but to set slightly different priorities: Thus, the glide ratio with neutral flap was improved in the speed range of 20-40 m/sec, which is important for F3F competition slope flying. At the same time, the stalling characteristics have been improved again, in order to be able to fly even more safely through tight F3F turns, especially at high flying weights.

These changes are especially noticeable when flying with negative camber of approx. -1 degree: In this case, the glide ratio and the climb rate are always higher than with the Quantum 1 at all speeds and weights. The sink rate is lower at all speeds, whereby this is particularly pronounced in the speed range of 35-50 m/sec.

A new feature is that the speeds of 50-70 m/sec. have been given greater consideration. Even though these are not usually reached in F3F competition, but only in a vertical descent from more than 300 m, they should also be improved. In the Alps, it is not uncommon to fly from these heights, so the fun factor has been increased again.

To summarize the main changes: New wing shape with less sweptback and a bit more rounded wing tip, a complete set of new 5 airfoils along the wing, new tail airfoil, slimmer fuselage, but the visual identity of the Quantum is kept.
