About the Engines

Reliable, practical and economical: all the things that pilots of large planes look for when choosing an engine. ZP engines tick all the boxes in these categories, providing power plants that really will be a case of fit and forget.
From the quality of the engine castings to the reliability of the Walbro carburettor these engines have a long-standing pedigree that now benefits from a boost in performance with the introduction of electronic ignition.

From a modest 20cc right up to an 80cc twin cylinder (boxer) there is an engine size that will fit most models from a 65inch warbird right up to a 30% aerobatic model, each offering simple set-up coupled with economical and reliable operation.


Equipped with electronic ignition that is powered by a lightweight 4.8volt - 7.4volt 2S LiPo battery, these engines are markedly lighter than other magneto equipped engines whist offering trouble free starting with a much smoother mid-range and improved top end performance. Weight savings have been made by optimising the design of the engine casings to minimise weight without compromising their integrity.

Other engine enhancements include lightweight silencers for quieter operation (included), machined anodised propeller drives and machined aluminium throttle and choke levers that make installation and servo hook-up straight forward and much easier.

These engines offer a simple “fit and forget” solution to powering a whole range of different types of models. Economical to run when compared to the typical cost of glow fuel, cleaner operation with no un-burnt oily residue over the model and reliable Walbro carburetors with little need of tweaking or adjustments as the needles are set to a default value at the factory.

Economical, practical, reliable, that’s a ZP engine!

The main advantages of an electronic ignition system over a magneto system can be summed up in three distinct ways.

Generally type for type there is roughly a 10% reduction of weight over magneto equipped engines, (not including ignition battery) the advent of lightweight Li-Po batteries maximizes this weight gain.

Electronic ignition systems make hand starting even easier and usually offer a better idle and smoother transition throughout the rev range.

Another benefit of electronic ignition is that the micro-processor automatically adjusts the timing throughout the rev range always providing the spark at the right time relative to the pistons position this generally allows the engine to run more efficiently.
