The Mk2 Firefly has a proper throttle lever for the LHS and a plunger-type for the other seat i.e. awkward for a short-@rse like me who spends his day at work in that chair stretching for the throttle.
The Firefly will sit all day in a stable spin and will do so all the way to the ground unless the correct recovery is used. The JEFTS Firefly abandonment accident report is in the public domain and involved the stude mishandling a spin recovery inducing a high-rotational spin followed by an unsuccessful delayed recovery.
