Description

The Lesley V12 model aircraft engine is 2 stroke and of a long stroke configuration for optimum power to weight ratio.  

Reduction Gearbox

It includes a reduction gearbox to enable the use of scale multi blade propellors. The gearbox can be supplied with a suitable ratio for the required scale propellor. The ratio can be from between 1:1 to 2:1.

Electric Starter

Starting is enabled by the inbuilt electric starter and a plug-in lead to the starter box with a 14.8V LIPO battery and electronic speed controller.

Ignition

The engine utilises an onboard glow controller to power the glow plugs which are hidden under the decorative rocker cover.

Fuel System

Fuel delivery is from an electric pump which is electronically speed controlled to deliver a regulated fuel pressure to the 6 carburettors.

The carburettors have a vacuum controlled valve so that it only delivers fuel when the carburettor sucks in air. It also has a mixture control system that is operated from the radio controls.

Cooling

The engine is liquid cooled and uses an electric pump to pump the 50% glycol/water mix through the engine and radiator. There is a temperature sensor in place of a thermostat to regulate the pump motor speed which controls the engine temperature.

Battery power for Ignition/Fuel/cooling sytems

The water pump, fuel pump and glow controller system are powered by a single 7.4V 5500 mAh Lipo battery.

Rear Engine Mount

The rear engine mount is machined from one piece of aluminium and designed to distribute the load over a large area to provide suitable support for the engine. It also makes it easy to fit to a fire wall.

Propellor Hub

The propellor hub is designed on a standard 6 bolt arrangement with M5 screws.
