The fastest model of this class with small wing area and high wingloading.
The relatively easy to stall on banking turn is partly explained by the high pressure at wing bottom is stolen into the cheating hole under the fuselage. Therefore, transparent sheet was added to act as guard to prevent high pressure air sucked into the EDF.
Test flight confirmed no easy stall on high bank angle turn, which happens easily on high bank angle turn from downwind to headwind direction.
She is now back to service and flying experience gives more fun than worry.
