A towplane uses most of its power to lift itself towards sky!
In a typical towplane/glider combination over 75% of power is used by the towplane.
A common towplane used today is built for too many purposes.
Each extra purpose includes drawbacks in this role.
PIK-27 archives better economics through following facts:
- it has no other purposes, compromises
- it is light, but robust enough
- it is simple, systems that do not exist, can not be go broken.
- it is easy to maintain.
