Really psyched about this Chris!
yeah, it’s amazing. It is deliciously slippery through the water. Under 12mm thickness and 100mm chord at the bottom, pumping high on the mast is immediately noticeable. Though this is probably the same as the plate mast of the same profile/dimensions. For me, it’s not as stiff as I wish for, but that’s the trade with such low drag. The tuttle is executed perfectly and it fits the box well.
We have everything in stock now! thanks everyone for your patience.
Ready to ship all mantas, orcas, most all tails. 75AX and 85AX, One more 75RC and one 85RC masts currently.

AX masts? That’s old tech… you’ll never get rid of those dinosaurs. We all want tuttles now

, waiting for proper forecast 
Is that a joke? What’s wrong with AX? Asking because I’m switching from code UHM mast to f4 ax as I’m using the largest foils 1250orca which don’t support the RC mast.
yes, it’s a joke. I used to run Tuttles. Love them, but old boards are near impossible to sell with Tuttles.
You sure you got your facts straight on masts. I’d be thinking RC only for the Orca 1250. That’s a huge span. Seems likely it needs the thick 13mm RC.

More a poke at foiling gear and the internet in general. By the time new stuff becomes available, it’s nearly obsolete. I kinda feel sorry for dealers…
I’ve given up on yearly foil ‘upgrades”
10.55MM thick mast?! F4, you guys are mad scientists.
Listen to the latest Generic Foiling Podcast if you want to get some tuttle froth going. I’m seeing an upgrade in my future, maybe next Xmas if I work really hard!!

Hi,
For the 1250 definitely go with the RC mast!!
The Tuttle masts are going to be interesting for a small segment of Tuttle board owners out there and they are largely the same design at the AX plate masts!!!
Br,
Chris

Thanks for the clarification, I got mixed up on the ax/rc. Is the rc better than the uhm plus code mast btw?
Weight of the 85 RC and Code + 85 are identical . Still waiting on wind to actually ride mine. Balanced position in the tracks is identical to Code also.

Hi,
I wouldn’t know about masts from other brands, but carbon fiber density is about the same for any type of carbon fiber. So if the volume is similar, the weight will be also if the laminate is solid for example.
I don’t know what’s on the Instagram post, but my tuttle AX is about 11.6mm thick and 100mm chord at the bottom. I personally wouldn’t want anything less stiff to be honest. The top section and the tuttle in the board are wicked stiff, which really helps, but you can really feel how thin it is at the bottom both in drag and in stiffness.

Finally got a winging session in 8-13 knots. First impression versus my Code. Short 170 tail has similar pitch and stability as Code medium 166 tail combo. Orca 1050 with its huge 1180 span, doesn’t roll like the Code 960 R with 1115 span, which I thought it might. It actually rolls much quicker. More like the Code 980s with 965 span. It’s so playful, it will get lots of use in my quiver. I was prepared for it to be a desperate days foil, but not so. If tomorrow’s forecast is correct, I’ll get to try my 800 Orca. Have not tried my 150 short tail either. I don’t see myself or the wife, wanting to ride XS tails. She is getting her knee replaced in two weeks. Once recovered, I’ll get her a 685 Orca setup. For context, ages 71 and 70.

Yeah, that insta post is about a race mast I think, so probably a longer chord to offset the thinness. Exciting regardless.
My Manta arrived and Its sitting next to my desk, waiting on the wind!

I did wet sand my logos down. The huge GP Series RC could be reduced to just RC to reduce drag. Logo paint is thick. Sanded the Orca logo to just a fade and lumpy feel is gone on surface. This is one area Code got it right. No draggy logos. I’m sure F4 could do the same.

This has been on my to-do list. Def need to set aside some time to get out the candles, set the mood, and treat these beauties right.

Disclaimer…I sell those titanium M6x35 screws linked above and everything below is just my opinion.
F4 uses a mast/fuse connection very similar to F-One and KT. They all rely on screw tension to keep strength in that connection. This is a known concern with F-One and, I believe, that is why they started offering titanium screws as an upgrade. KT is in a different category since the connection is much beefier and uses M8 screws.
The only suitable type of titanium for screws is grade 5, also known as 6Al-4V and it’s tensile strength is almost double that of 316 stainless. A4-70 screws are 316, the most corrosion resistent commonly available stainless, but really no stronger than the more common 304 (aka 18-8). The problem with this type of stainless is that it is very easy to stretch the screws in M6 size. You can feel it when you tighten things up but you probably won’t notice unless you’ve used higher tensile strength screws before (because they don’t stretch). In stainless, what you want to look for is A4-80. They are much stronger than A4-70 and don’t stretch much when tightened. Problem is they are very hard to find and Accu doesn’t offer much…I think only M6x30.
Titanium and stainless are both prone to galling. Use some tefgel/grease/etc. if you feel like it and don’t use an impact driver and you’ll probably never have an issue. I disassemble all the time and I honestly don’t worry about wearing out threads. Titanium is rarely really required for any foil parts but for this type of mast connection, I’d go for the strongest screw I can get…A4-80 or grade 5 titanium. I lost a complete wing a few years ago and am very cautious with those small M6 screws. Replace often if using stainless (very cheap insurance) or go with something stronger but still keep an eye on them. Stronger metals will snap when they fail, softer will kind of tear. Every tightening/stretch cycle is like a micro tear…eventually the fatigue will be enough for the screw to let go. My opinion is it doesn’t matter how it fails, but the main thing is that it’s stronger so it’s less likely to fail in the first place.

Hi are there any heavier riders here (195lb+) using the 80cm AX mast with the 800 orca or larger? If so, how does it work for you? The website doesn’t recommend the AX for larger riders but I really want to stick with an 80cm mast length.
