1250, 1000, 800 and maybe a 650 (don't quote me on that).

the 1250 rides a bit more like the 1550 size / area wise. 1000 more like the 1250 - or a tad under as my mate said when he rode it.
so go a size smaller compared to the HS basically.

add in the new modulus mast which will transfer the wings power far more directly. The old land wiggle test compared to the A plus mast is noticeable torsion stiffness. Compared to my original, the original feels like a pool noodle.

oscar was saying the new 935 mast there is a signdidant difference in torsion control and incrrased speed on the water. Far easier to pump.

everyone is after a stiffer mast, but listening to Oscar and armie there is a whole lot more to it than just making a stiff mast. You still want it reactive at certain tilts and mast depths.


Not that I got what materials and shape engineering took this into account. Way over my head. But there is some different materials and shape voodoo across it's entire length.

No nothing on the tails except to say when I rode with armie he had a prototype on there and was liking it. I know they are bringing out a tail to match the MA evolution and it will come in a few sizes. That's all I know.
long time until Christmas - I'd get a 195. Personally it's all I use now. Still be a relevant tail to the MA.

No mention of new lay ups on the A plus mast.


I can vouch that the A plus is way stiffer than the original. I still use the original. Son has A plus. Both the beach Torsion test and in the water is very noticeable.


yes you are right about the concave on the pressure side. Armie talked at length about the relationship between this concave (where it starts, finishes, the degree of concave, and how the rest of the pressure side design works with it).

the main thing he talked about was the more concave the flatter the non pressure side has to be. There is an optimal cost benefit relationship here.

Original Slingshot wing had it too, called undercamber in the aviation world. Adds lift at the expense of drag and reduced pitch stability.
Not exactly intellectual theft by any of them so much as experimentation.

Do you know when that change took place? I have an early A+ mast that weighs 1700g, wondering if has the stiffer layup.
Armstrong lists an 85 at 1500 g which doesn't sound right.
Thanks

My apologies I posted this is the wrong thread. For those that weren't at the talks - this podcast covers it all and some further information.

Saw this

Where? I don't see it on Armstrong website.

MrBennetts is ripping the bag out on an unspecified wing.I wonder what it could be?
