A TL Ultralight Sting S4 costs approximately $169k (€156k) to $202k (€187k) to buy at 2025 market values, and about $16k (€15k) a year to own flying 80 hours, roughly $203 (€188) per flight hour all-in. It seats 2, cruises at 115 kt (132 mph) and has a published range of 700 nm (1,296 km), needing about 984 ft (300 m) of runway. Figures are indicative planning estimates compiled 2026-07, not a quote for any specific airframe.
The Sting S4 is a Czech composite two-seater built for touring rather than training: low wing, sleek, quick on a Rotax and comfortable enough to cross a continent in, which is what its owners tend to do with it. Build quality and finish are noticeably above what the price suggests. It belongs to the light class, with everything that implies. Cabin load and baggage are modest once two adults and fuel are aboard, its weight limits and permitted operations depend on the national rules it is registered under rather than on the aeroplane itself, and support runs through a small manufacturer and its importers. Buy it for two-up touring, having first confirmed what your authority permits.

Efficient and pleasant for recreational touring, but useful load and baggage margins are limited.
Indicative cash costs at 2025 market values, before financing, depreciation and tax. The fixed base is the same whether the aircraft flies or not, so the effective hourly cost falls as utilisation rises.
| Annual use | Annual cash cost | Effective cost / h | Five-year cash outlay |
|---|---|---|---|
| 40 h / year | $13k (€12k) | $324 (€300) | $248k (€230k) |
| 80 h / year | $16k (€15k) | $203 (€188) | $265k (€245k) |
| 120 h / year | $19k (€18k) | $162 (€150) | $281k (€260k) |
| 180 h / year | $24k (€23k) | $135 (€125) | $305k (€283k) |
Every figure above is built from a $10k (€9k) fixed annual base, covering hangarage, insurance, scheduled maintenance reserves and recurring airworthiness costs, plus $81 (€75) per hour flown for fuel, reserves and consumables. It is a planning model for comparing aircraft and testing utilisation, not a maintenance programme quote, insurance quote or pre-buy assessment.
Older examples add calendar-driven maintenance: a 2011-built airframe is estimated at $19k (€18k) per year at 80 hours. Airframe and engine time, maintenance and damage history, avionics, equipment, geography and tax treatment move a real transaction further than the model year does, so price the aircraft in front of you, not the model. A cheaper example carrying deferred maintenance can be the more expensive aircraft once the first annual inspection is complete.
TL Ultralight Sting S4 cost guide answers the same figures as standalone purchase and ownership questions, and the ownership cost calculator lets you replace these assumptions with your own hours and fixed costs.
Nothing beyond a pilot certificate for the category and class. With fixed tricycle gear and no endorsement requirement of its own, this is among the simplest certified aircraft to qualify in, which is a real part of why it is cheap to insure and easy to check out in.

An indicative 2025 market price for a TL Ultralight Sting S4 is $169k (€156k) to $202k (€187k). This is a planning estimate normalised across the market, not a quote for a specific airframe. Condition, engine time remaining, avionics and damage history move the real number more than the model year does.
Flying 80 hours a year, a TL Ultralight Sting S4 works out at roughly $16k (€15k) annually, which is about $203 (€188) per flight hour all-in once fixed costs are spread across those hours. The direct cost per hour alone, covering fuel, reserves and consumables, is about $81 (€75).
Reported range is 700 nm (1,296 km). PlaneFit does not yet use this figure for mission ranking on this model.
Plan on approximately 984 ft (300 m) for take-off. Check this against the actual runway, surface, slope, temperature and loading, all of which extend the requirement.
