Without a person aboard
An aircraft in the size class this laboratory works in costs far less to build when no one flies aboard. The weight, volume, and interface a pilot requires do not just disappear. They become useful load or better performance.
The platform
One piston engine with a tractor propeller, running on automotive gasoline. Maximum useful load 400 kg. One person tows, deploys and launches it from unprepared but inspected field strips with 300 metres available. Range extends generously when traded against load.

Productive capability
The work is repetitive, flown low and close to obstacles, or needed at hours and in conditions when supplying a crew is the hard part.
Precision agricultural spraying, day or night. Aerial application that demands long loiter, such as hail protection placed on the spot and on demand. Emergency response supplies. These needs come from land owners, territorial services, and other civil entities.
