    Default Radtek Powerboats 24" and 92" Catamarans

    Ok, as promised, here is the website and video.

    www.radtekpowerboats.com

    http://www.youtube.com/watch?v=LfRrWrMTyAw

    The video is rough, we will have better soon. Also one of the $10 chinese test motors failed just after this video and you can hear me complaining about it. We will be testing the little screamers motors this week.

    If you haven't been on any of the other threads, our boats are just finishing testing and we will hopefully have them for sale soon. The are based off the dimensions of the full size offshore powerboats. They are made of all carbon fiber or carbon/kevlar hybrid.

    Please ask any questions.

    Hi Justintime2w8

    Awesome boat! well done.

    Is the boat using counter rotating prop or same direction rotation prop?

    Cheers

    This should answer both questions. Now, this is just test stuff, so don't critique appearance. This is the hardware used in the video. All bought from OSE! CR? Why not.

    Is it going to be possible to get this boat without the hole for the antenna to come through?

    No holes will be drilled in a bare hull, if that helps. I went with an external antenna due to the carbon-fiber, that and I am over cautious.
    Here is a pic of what black carbon will look like. We will have better pics of this hull soon.

    Like my gas KOS, it does not corner well and I think because it's so dang narrow?
    slow to mid speeds look good, but not full throttle

    All fast boats slide in a corner.with a cat turn right and the right side of the cat does the turning and the left side slides abit because the small over powered boats go so fast. the left side slides a bit so you need some angle to alow the water to pass under the left side. the MM has the right angle and width to make it one of the best turning cats to date. look at the back of a mm and look at the back of this cat. this cat has planing strakes on it and the ones on the out side will hook up in a turn and flip the boat. I would like one but I wold like the planing strakes taken off. this would make it turn much better. put some kind of removable filler in the planing strakes in the mold and make one with a bottom like a MM and it will turn better and then sell one like that to me.

    ok, way over my head...
    is there anything I could do to my Gas KOS to make it take the coners at full speed?

    Brushless 55 e-mail me some pics of the bottom of your boat in side and out. The inside need to be close ups and of the out sides bottoms. The out sides I will need one from the back to. If the 92 is the same as the 24 It can be fixed.

    The length to width also is a large contributor to the hull's running characteristics. For example, the mean machine may corner well, but I have not seen any break the 100mph mark. The hulls we build are scaled off the real thing and perform similarly.

    Hi Justin,
    I wanted to know what Kv the motors in that video were too? The motors I gave Rad to test for the current 24" cat are 4500Kv.

    Those were 5100kv, but really junky. Rad is going to run yours and I am going to run a little better set of 4000kv. We should have videos next week some time.

    A little "better" set than the 5100's Due to the load loss the 5100's had, our 4500's make more torque and will hold closer to their rated Kv

    Good, so far, I am getting excited about performance. Seeing how well the boat ran with the cheapie motors the hull should literally fly with the current two setups we have. Should have more videos later in the week. We hope to get a radar gun on them too.
    Other than that I am selling the pair of Neu's I traded you for. Obviously, I have many other projects that need the funds.
