How to tune stepped mono for racing?

[Jesse J]

Here is my latest test with Joseph's syncron.

Does anybody know of someone who has gotten the H&M chief tuned well?
I'm oh so curious. I tried a big turn fin and she banked OUTWARD!!
How dat work?

Hey Erik, do you know of any more recent setups, a lot has changed in 5 years.

Your turn fin is still canted over too much and as it is slipping sideways the angle on the fin is forcing the that side upwards, so the bigger the fin the higher that side will ride, and you need to stand it more upright to remedy it. I felt sure I mentioned that as a possible issue earlier, but now reviewing the thread I can't see it, maybe I posted in a different thread, but whatever, the effect of the bigger fin confirms that it is at the wrong angle, and extra lift at the rear during turns would also explain the hooking , so you may cure both issues with a single easy fix.

The setups Erik posted are still valid, Mark Shipman is still running both of those boats and still competitive with them, he is the clubmate I spoke of earlier that switched from Lehner to Neu, although back when those were posted he was still running the popular Leopards I mentioned.
Dee is ETTI's team and test driver so he always has either the latest hull or a secret project and isn't driving those any more, but as I mentioned before the differences between hulls is shrinking as they are converging around the ideal for the course. We only have about 10% more power than we had in those setups, and while there are newer and better all round boats, they are still absolute beasts in calm water conditions, and the setups for the new ones which have a few more degrees of deadrise and a lot more hydro nose lift that is out of the water 95% of the time will be very similar indeed.

Leopard 3674 1700 are a popular motor for 6s Mono2

There was a race last week and I took some pictures of the rear end of well set up monos for you, I was horrified to find out that when I was taking the photos peope were thinking i was working on a mono myself, so I didn't get out a tape measure and angle gauge.

Sweet, thanks Paul! Ok, you've convinced me... I'll go vertical.
Yes you did tell me, I just haven't had the time to redo the turn fin.
Gonna make in as deep as the keel and 2" wide, sound like a good start?

Thanks again for the recon pics, and for going under cover as a mono guy.

Question: has anybody run the Skyper mono1, or speedman mono II by hydro and marine?

The skyper call it an open flood chamber? Is this accomplished by weights to port side?

Any comments on setup and performance of either/both?

Hi Jesse,
I had both in my hands: the Skyper was mine and I raced it for about two years, the Speedman I installed for a friend. The open channel in the Skyper is a pain in... you either partially close it, add weights or install a small internal chamber they usually provide. As performance, it was very good, but not something impressive, due to the fact that it was a bit on the heavy side. It was actually replaced by the King Cobra, which is the same hull with a different (normal) top.
The Speedman was a joy to build, excellent quality and it ran perfectly from the first test. Two years ago, at the Naviga world championship, there were still a couple around doing well.
In brief: good hulls, but they are almost obsolete... As options, consider newer ones, like the Etti Sirius for mono 1 and the Rasch Tomcat or QEssenz for Mono2 (I am in love with this one).

Hi Cornel, thanks for your input; how does one order one of these from the US?
Both are beauties, but I'd prefer the tomcat.

[CornelP]

I think you can contact him on the website, he usually answers within a day or two.
You can also ask him to install the floodchamber and ask for a race spec (lighter but a bit more expensive).

So, now a question: what is fun sport class? This chief is proving a significant challenge.
What voltage/motor/prop are guys running this on?
Thanks

[NativePaul]

Hydros.

[Jesse J]

What??? That is the class H&M advertises this chief boat as... bah!
I'm getting the idea that nobody races this hull...
