The first engine in the new AX series draws on years of experience in providing the best engines money can buy. The new 46AX now features a new rear-mounted needle valve system that tolerates crash damage better.

The new carburettor has been refined further to make adjustments more precise and throttling even more progressive.

The amazing new 'P-Box' silencer is both distinctive in styling as well as being functional. It improves power and keeps sound levels to a 'purr'. Inside, the 'ringless' piston/liner system delivers strong power and improved life.

Physically identical to the popular 40LA but with a 20% increase in power and no discernible increase in weight. If you’ve built a model that’s ended up a little on the heavy side for a 40LA then the 46LA could be the answer to your prayers! Like all engines in the LA range the 46LA comes with an A3 glowplug as standard plus the highly effective E-3030 Silencer.
