Turn fin for a 45" Hydro

[Jake Ellwood]

Hey all,

I've picked up a 45" Miss Budweiser hull from MHz Powerboats and plan on fitting a CMB 90 to it.

Going to need a turn fin for it. Anyone have any guidance on sizing for one and also any links to suppliers please?

Much appreciated

Mike Hughes makes them as does Virginia Craftsman.
Both are here on the forum though, unfortunately, I don't remember who the Virginia Craftsman is, just that I have one of his fins and brackets.

Thanks very much! I'll do some googling. That gives me a start point!

Virginia Craftsman is Dick Tyndall. Also consider AccuTech (Accu-Tech RC Hardware home page) and Bill Brandt is offering one on his site (Nitro 1/8 Scale Hydroplanes Rc | Rattlesnake RC/Allrc1.com).

Thanks Dean. I knew if I mentioned VC someone would fill in the blank

Thanks everyone. Also is there any sizing advice when it comes to turn fins? Looking at the ones posted so far, they all vary in size, design, shape etc. Anything to be aware of?
I won't be racing this boat, but am aiming for it to be quick and handle well.

Thanks all!

It really depends on the boat and driver:

• Some like a fin with a hooked bottom end, some don't.
• Some like a flat fin that is angled inward at the bottom
• Some like wide short fins, some work better with long and narrower

The only thing I know of relates to a hooked fin. You have to make sure the hook is parallel to the bottom of the boat. If it's at an angle, it can either lift or pull down on the boat, affecting speed and handling. If it's set properly, they work well.
When it comes to what works the best, it really comes down to try a few different fins and configurations and see what you prefer. If you look at what the full sized boats have used through the years, they have been constantly changing so there isn't really a right or wrong answer to this

The zipp kit twin 45 turn fin would be perfect for you. Very friendly price.
