Speed indicated is this expected actual?

I am getting 21 meters/second about 68 feet/sec. This seems a little faster than I would expect. Does anyone have any radar gun trials with any of these planes?

Speed is controlled by many factors. It is not really based on reality.

It can be adjusted in FMS by many items. The wing POLAR influences speed.
The MOTOR items, the DRAG settings, the size, weight and moments all
influence speed. The easiest way to speed up or slow down an ELECTRIC
model is to add or remove cells or voltage. Each cell is 1.5 volts. For
COMBUSTION motors, just increase displacement.

If the model seems to slip through the air too easily, increase total DRAG
or drag area for the model. Conversely decrease one or both for a model
that seems to be slugging through the air.
