That doesn't do those of us who don't go to the "other forum" a whole lot of good now does it? How about a link?

Fins are in the wrong place they need to be on the outer corner where chine meets bottom, also they look too big ie they look like they will be in the water when boats running straight which isnt how they should be.Turn fins should only touch water when the boat leans into a turn.The way yours are they are causing drag as theyre in the water all the time.

Link- RCGroups and look for said subject. You don't have to join, just look. People gave honest answers in a decent manner and wasn't smart about answers.

I just gave him an answer right here on rcu so no need to look on other forums.Heres a pic of turn fins on a gas boat notice the size in relation to the size of boat plus the placement.

Yup, I replied to him also on one of the other sites.
In a nutshell and wasn't mentioned here was that he put them on as he was having chine-walking problems. I wasn't a bit surprised as that's a lot of prop for such a small hull. It comes down to 2 things, a smaller diameter prop or the need to raise the strut height.

The prop wasn't the problem i don't think , it was a little bigger than stock but different pitch . it was the Octura x640 Diameter: 1.57"
Total Pitch: 1.6x1.57=2.512"
sharpen and balance . the stock has the.Dimensions: 39 x 13mm .

Now that Ron mentions it that prop does look big,how long is this boat out of interest.
Also looking at the bottom of the hull nothing is sharp all the strakes and the transom look kinda rounded,typical of many vaccum formed plastic boats.My thinking is you will never get it to run that well for this reason.When manufacturing a boat you need to be sure these areas are sharp,if not the boat just wont run right in my opinion.
This one of my 58 Apaches notice how sharp the strakes and chine rails are.
