This mast got me back on Armstrong. As a 95kg rider this mast is a perfect balance for a multi discipline rider. Stiff enough for riding big foils dw and also fast enough for high speed winging and towing. 🎉 great job!
Ridding the Performance mast 865 with the new HA780. I love it: fast, responsive and forgiving. Reached 40 km/h on the first session and I am an average rider. Thanks Armstrong for sending us to the moon 😊
That moment at 2:23 where that carbon mast deforms terminally 😫 I'm waiting on my first ever carbon fibre mast's resin to cure. 2 more days because I used river table epoxy to do a very slow resin infusion in my 3D printed mould. Over designed because I don't want breakage! Suspect I'm too heavy AKA "fat" to get longevity out of the hex coupling in an Armstrong mast but if I was lighter and younger.. Maybe.. But the ability to taper, to flow fibres in the mast design's mould to address stresses and seek an ideal mix of efficiency and glide, it's so much fun to make it right.
Hi Peter, indeed we developed these masts specifically with the mix of carbon types because HM's stiffness minimizes flex in the mast's central strut area and IM's high tensile strength caters to the complex shapes of the top plate and fuselage connection.
@@armstrongfoils Agreed, I'm still learning about types of carbon but many forget that most manufacturers do even small wings with high density foam inserts which are aren't carbon fibre at all. Tension on a bend's outer radius will always be more than at a slightly smaller radius. So fibre with slightly more stretch works with higher tensile rating fibre at an inner radius if you match perfectly, to keep within the breaking strain of the chosen fibres at different radiuses of a bend. I imagine you are splitting your fibre sides at the top plate for continuous skin all the way, i can't imagine any other way to get good flow through strength.

The best mast and products in the foil space 🔥
❤❤❤ Exactly how it feels on the water!

Combination of HM and IM carbon : thus not full HM carbon
