~3.15 hour of flight, single take off, engine not used.
SM Pitot mark 2 dives over 350 km/h (217.5 mph)
3 dives at ~330 km/h, (205 mph)
2 dives over 320 km/h, (199 mph)
and 2 'regular' at ~300 km/h, (186,5 mph)
Then other up to 290 km/h..., (180 mph)
The chart show the following dives (no DS)
of SM pitot:
MAXSPEED to 376.16 kmh (233.75 mph)
other 2 at 366 kmh (227 mph)
1 to 351kmh (218 mph)
1 at 344kmh (214 mph)

1 at 305kmh (189 mph)
1 at 274kmh... (170 mph)
1 at 271kmh (168 mph)
..and all others under 216 km/h (134 mph)
Start point at 1460m, a low altitude.
This model (even if heavy) is small and it have a limited mass (~6.3kg , 13.89lb)
The airfoils in use, are not 'racing foils' as the series 'R', but instead are a middle ground
among other not even laminar.
These allow as demonstrated, however a good vmax,
the ability to make fast aerobatics (fast-
without however becoming especially critical even in tight maneuvers.
The slope not give the same yield throughout the day,
but stay in the air more of 3.5 hours with F4-
It is not at all uncommon.
