A fair number of army co-operation squadrons had been equipped with Lysanders, both in France in in England.
Sopwith Salamanders would have just wonderful against "real fighters" too.
on a more serious note "118 Lysanders were lost in or over France and Belgium in May and June 1940, of a total of 175 deployed"
and
"The view of Army
AOP pilots was that the Lysander was too fast for artillery spotting purposes, too slow and unmanoeuverable to avoid fighters, too big to conceal quickly on a landing field, too heavy to use on soft ground and had been developed by the RAF without ever asking the Army what was needed"
The Lysander may have had a slow flying speed but it also had very heavy controls which made changes of direction ponderous.
Slow and agile might work. Slow and not agile was a recipe for disaster.
