In level flight we are at 500k NRe around 30 m/s,
the AB330R, laminar airfoil at 10%, is found to work
in its environment, allowing dive to great effect.
Efficency above the 25 to almost 29,
and maintained with a wide range of incidence,
combined with vertical speed low,around 0.82 m/s it also easily
maintainable, we have a model fast acro, maybe a little light,
but ballastabile, that does not fall easily, even in poor conditions
