Parajet XT Aero Engine FROM $2,879

Features & Benefits

Crankcase & prop-bracket - The prop-bracket and crankcase have been combined into one component and all unnecessary material removed but with strengthening fillets added to the critical areas. Fixing screws have been reduced in length without compromising strength. Gas flow within the crankcase has been improved and the overall volume reduced both of which enhance performance. Oil-ways to the crankshaft bearings have been modified to improve lubrication. Greatly increased surface area of the crankcase has also improved cooling.

Starter motor and bracket - the existing starter motor has been retained but moved closer to the carburettor making the unit more compact. The starter bracket is now mounted to the crankcase and been changed to reduce weight, improve support and simplifies mounting and dismounting of the engine.

Ignition system - utilises a single-point ignition system making this engine not prone to pre-detonation which is the major cause of catastrophic engine failure in 2-stroke aero engines due to holed pistons. Our much lighter, stronger and corrosion-proof magneto wheel is now manufactured from stainless steel.

Battery - the lead-acid battery has been replaced with a Lithium Polymer unit. The disadvantage of having to charge this battery outside the machine is more than made up for buy the weight saving and the greater number of starts between charges. The problem of leaking acid has also been eliminated.

Propeller shaft - the eccentric propeller shaft is manufactured from stainless steel and considerably lighter. The clamping bolt has been enlarged to 10mm and now engages in a groove on the shaft to prevent it from sliding in the clamp. This has eliminated the need for the retaining washer and screw.
