Its main purpose is a local hobby flying and a flight training as a complement to twin seat elementary trainers like Letov LK-3 and ST-4 or TL-32 Typhoon.

Sluka does not offer any advanced training possibilities in respect of performance, speed, ceiling or aerobatics compared to the mentioned twin seat models but its purchase price and cost per flight hour are lower.

In 2010s it is usually operated by private owners and enthusiasts as it never was widely used in aero clubs which preferred modern composite or metal designs with better performance and fuel economy usually powered by the 4-stroke Rotax 912.

There is only one switch for magneto cut-off in standard but it is widely customized with integrated alternate current generator and battery to enable power for electric instruments (radio, GPS), beacons and Rotax electric engine starter making the aircraft more comfortable.

Custom upgrades can be of different kind usually providing communication radios, different GPS devices, integrated engine instruments, Hobbs meter, ELT or turn indicators.

Maintenance is also easy as there is almost no cowling, engine and fuel installation can be easily inspected and steel wire controls are mounted on the main fuselage tube.

Its design was then adapted for the newly established Ultralight association as a future type to enable private flying with low costs being sold to existing Aeroclubs.
