The W679 is a wing with a wave-oriented DNA that allows you too slow down before starting any manoeuvre, then accelerates fast and with a high cruising speed.
Compared to W633, W679 has higher lift speed, wider curve radius and better control at high speed.
A very versatile wing, more oriented to manoeuvres with the S483 stabiliser, or free-riding with the S330 stabilizer.
Always keep the threaded holes clean and lubricate often by using Lithium grease (code MHW033) to avoid and prevent oxidation and corrosion due to sea water.
