Sorry i meant loose 3-5mph or so not add or gain. i cant notice the difference turning with or with out them.

Most of the hooking is becasue of the sponson design. Your rudder looks to be plenty deep so doubt that is the problem. A wider sponson at the rear could help and removing the one step. It is the inside edge of the opposite sponosn that helps keep it stuck in the turns...not the out sponson edge. Hope that makes sense.. Inside tunnel edges need to be nice and straight and sharp.

The tabs can help but if the design is corrected you do not need them. These are not tabs but spin fins. You may want to keep the trim tabs on to adjust for corners....it will keep the hull up a bit when slowing in the corners.

The hull design they have is more for looks than performance. Look at some real steps on real cats to get an idea of what I mean. Calllan/Mystic hulls have a round outter edge so the water actually rolls under the hull and not act as a straight edge out there so when water hits it is is like hitting a brick wall.

Thanks Jeff, that's kinda the way I'm leaning...no pun intended. Iwould like to get the spin fins back off.

I have to say...all of you testing and trying to push the BJ 26 should be proud. Not many box boats can handle it. I see Anthony made 55 mph and running 6S thru the stock system...holy cow! Those are well built motors but never thought the ESC could handle that....nice to know.

So hats off to all of you guys pushing these hulls to the max. I'm sure many of you came off the water with shakey hands!!

With all the talk of hull modification I'm tempted to try it. Now will the hull mod help more in straight line speed or just cornering? I honestly don't care about cornering, this boat is just to play around with and see how fast I can make it go in a straight line...

Up next, just picked up a Hydra 120 and already have a NEU 1515/2.5/F

Anytime you can widen a ride pad, without going overboard, it should run faster. I was thinking it may be easy to put some abs to the bottom at the rear and then use some filler to round up the sponsons on the outter edge. I used ride pads on all the earlier cats I had. It made a big difference on my Scat Cat 32. I also use them on my hydro front sponsons....give a nice clean and sharp edge.

You may find just blueprinting the bottom can get you closer to 60. Flat, straight and espcially at the rear of the sponson should be nice and sharp coming down from the transom.

I use sqaudron putty. Forms easy and sands easy and then just paint. Or you can use Bondo that works very well too and stronger. Just catch it before it sets up hard to do first shaping.

after my hull mods mine helped in both cornering and striaght line, alot more stable.... here are the pics if anyone missed them http://s228.photobucket.com/albums/ee126/john_watkins1/

The last couple days I have been laying down balsa and fiberglass. I filled in the last set of steps w/ balsa wood first. I then went to the angle part to the outside of the ride pad and put some angled balsa stock there, making the outside more rounded. I then laid strips of fiberglas about 1 inch wide on top of the outer part of each side. The back of the hull rounded out nice. I'm letting spot putty dry right now. Tomorrow I will finish sanding and get some high build primer put on. Hopefully my buddy KSSI wil post a couple of pictures for me. Starting to really look good.

any pics? ride pads? more explanation please

It's at KSSI's house drying. I'll try to post some tomorrow.

I'll now refer to you as MR. Wohlt. I filled the last set of steps and rounded the back end out. What a difference. 40mph down the straights and pry 35 through the corners. The thing never ran so well, Thanks.
