I decided to change my previous retrofit as explained in my previous topic.
Thinking maybe it will be better, safer, stronger to attach the Slingshot H4 batwing chinese copy with stabilizer wing & fuselarge to the Neilpryde mast.
But it will mean I will have to load an extra fuselarge & stabilizer wing in my carry bag & car. No big deal.
Main reason being is that the chinese copy mast had bending issues when hit side on by a wave which had ended some of my sessions too early! Plus wanting to have a quicker change over.
I can now change over both NP wing assembly & the H4 Batwing assembly onto the NP mast if wanted.
I only had the short fuselarge & not the Switchfuse. Too expensive in my opinion.
I drilled & roughly countersunked the 3 holes in the fuselarge.
For the batwing to be attached to the fuselarge I only needed two stainless 8mm bolts long enough to bolt into two nuts that I fitted inside the mast hole of the Batwing. I had to file two corners of one nut to fit it inside. So won't have to buy that expensive fitting that fits in the mast hole either.
Also by having the NP mast behind the Batwing instead of in the Batwing I might not have to move the mast mount on my board when changing over.
So yet to try it out. Will let you know.

Why? I'm confused? Both masts are dogs, the slingshot tho is cheaper and more readily available.

Ok. So you may mean that both masts are dogs regarding weight and fill with water.
But it's way more cheaper to drill 3 holes in my existing Slingshot copy fuselarge to fit the Neilpryde mast. Than buying another mast.
And yes I to was annoyed at Neilpryde gear availability. But too late after my purchase.
And easier to just exchange both the NP fuse or Slingshot fuse. Than removing & attaching different mast plates and foils. I was initially hoping just Wings but may be unsafe.
Just to explain. I had a Chinese copy of the Slingshot H4 Full Assembly as my very first foil about 4 years ago purchased on ebay. I took the chance to purchase at approximately $400 cheaper.
The copy was basically exact in dimensions. But, maybe the grade of aluminium was lower. So my mast bent in waves that were around shoulder to head high.
Just a couple of years later the Neilpryde foils came out at a cheap price with strong enough construction before carbon masts became common. And from what I found out the Slingshot 76 & 84 wings at that time had delamanation issues when I was contemplating just to buy a Slingshot wing.
So I decided it would be more wise in purchasing the Neilpryde going by its positive reviews against buying a Slingshot wing that may end up faulty on my Slingshot copy mast that had bending issues.
I still love using my Neilpryde foil and the mast has not let me down in performance & strength.
Also my Slingshot copy H4 wing & fuselarge assembly is still going strong so that's why I want it on my strong Neilpryde mast that doesn't bend.
But it has been about 2 years since I've used the H4 Slingshot copy wing as at that time it seemed to have less stability. So I'm curious now to find out how it performs again. Just another challenge to find if it will fit another foiling surf style.
I'm thinking the H4 slow speed, less lift will enable me to surf closer in the pocket or shoulder of a wave as well as being a little looser in turns as it was originally designed for.
Plus I'm wondering if it will handle more overhead conditions?
I know the H4 has had good reviews in kitefoiling performance. I think it is called now as the Space Skate wing.
So wont be long to try it out.

Just to let anyone know if interested.
Tried it out today in shoulder high waves & it performed ok. So I'm happy with it.
I was happy with my stability considering this wing is more unstable than most.
I had a few side to side wobbles on the first two waves but quickly gained stability. Happy to know my foil surfing ability has improved since getting off this wing around 2 years ago.
So I think this wing would be good for stability practice for the fun of it.
I have yet to get it out on more gutsy waves to check its full performance to make any minor adjustments if needed.
