Like all the AX series, cooling has been improved by the use of deep finning on the crankcase and cylinder head combined with the new fin pack shape.

The silencer is effective and a great benefit to flying fields with sensitive noise iossues. Effective silencing is very much part of the AX design philosophy.

Carburation is the usuall OS ‘exemplary’ standard and very much why OS engines are regarded as the best! That comes from careful design and testing allied to stringent manufacturing standards.
