Evolution .61NX Glow Engine
from Horizon
Two stroke engine

The Evolution .61NX is a direct replacement for the original .61NT. The new more powerful 61NX incorporates a new combustion chamber that increases the compression and power of the engine while keeping to the same compact size and weight. Along with these internal modifications the 61NX has a dual ball bearing supported crankshaft for smooth vibration free running and also features the easy to use Set-right carburettor with rear mounted needle for safe adjustment and hassle free running, a sleek external crankcase complete with a new deeply finned anodised blue cylinder head allowing better airflow and even better cooling. Complete with silencer this engine is the ideal choice for 60 size scale or aerobatic models.
