Thor 260
Thor 260
Safety in flight and attention to consumption
The Polini THOR 260 was born from the desire to create a balanced “cruise” engine, for an increasingly demanding market in terms of reliability and consumption. With a weight of 21 kg (including radiator), the new Polini THOR 260 guarantees an excellent compromise of stability and power.
With its 36 horsepower at 8000 RPM the Polini THOR 260 is capable of offering up to 105 kg of static thrust with a 160 cm propeller.
Consumption is only 3.5 liters per hour at 4500 rpm, which corresponds to approximately 30 kg of static thrust, average level flight value.

The Polini THOR 260 is equipped with an electric starter combined with a manual "flash starter". The excellent reliability/power compromise allows the THOR 260 maximum versatility for use on single and two-seater trikes and delta trikes. The new THOR 260 is available with a choice of two different reductions: 2.8 (recommended for propellers up to 140 cm) and 3.2 (for propellers over 140 cm).
