    New guy and questions of course!

    Hi folks just signed up I'm new to RC boats and FE boats but have done car's and heli's I'm an older guy and my background is electrical engineering.

    Here are couple of my questions I building my first boat I'm thinking the River Cat Hull from Fighter Cat or the one from Kintec but by looking at them they seem to be the same hull appreciate any thoughts. I'm open to any thing in a 32" to 37" Cat hull thats decent for a first build.

    I'm set on a Cat hull but I thought I would stay away from the H & M or other pricey hulls I don't want to screw up a really good hull!!! I have never purchased a boat FE or otherwise the electrical part for me is no issue I can do that in my sleep now the mechanical part that's another story.

    Which leads to my next question I'm considering a twin setup, are there directions in the kit on how to install stuffing tubes, things like max radius of the tube bend (not much concern in a twin set up) were the prop should end up in relation to the hull, etc all have me a bit stumped and I can't seem to find a step by step guide anywhere?

    This is a sport build with a goal of approx. 50mph nothing to hot.

    Thanks in advance.

    Hi Lockk, welcome!

    50mph might seem like nothing too hot, but if you are going for 50mph onthe first run of your first boat you had better wear brown trousers/pants and bicycle clips on the test day! 50mph seems a lot faster and more exciting on water than it does on land or in the air.

    Twins are more complex and expensive than you need as a first timer but theres no denying that they have a cool factor, the stingers on a twin set the position of the prop, install the stingers on each sponson as low and far towards the center of the boat as you can and start with sitting the boat on a flat table and adjusting the angle of the stinger's tail so it is parallel with the table.


    There isn't really any set minimum radius for flex shafts, they will work at quite tight radius as in an outboard drive leg, but the tighter it is the greater the friction, so bend the stuffing tube to the biggest radius that you can while still leaving an inch or so straight at each end, and make sure the bend is smooth so there are not any areas that have a tighter radius than needed, I use a drill bit in the motor coupler to make sure the stuffing tube lines up with the motor. Once bent to fit I glue it in using 30min epoxy thickened with micro-balloons (I have seen some use JB weld, which looks like it needs no thickening to stop it running).

    I haven't bought a hull from Fightercat or Kintec so cant say for sure if they have step by step instructions for assembly but I doubt it, from my experience the best you can hope for is a list of recommended equipment and a diagram of where everything should go in order to achieve the correct (marked) CoG.

      there are alot of build threads you can look at before you make your final decision. the fighter cat and kintec hulls are very similar if not the same. i would say either one is a good start. those hulls are better going in a str8 line, as opposed to a mean machine which will kill them in the turns

        You also may want to consider a single for your first build. Simpler set up and troubleshooting. I bought a Daytona hull from Ben at Fightercat and he has been very helpful all along the way. Also this forum is an incredible resource. Lots of great people. Welcome to the forum and if you have questins ask away.

          lol... Paul the goal is 50mph,,,, not the first time out I'm going to battery down but put decent components in that will get me there.

          Thanks for all the information thats a big help, I also found the tips area on this site and went to the site in your signature which was helpful too.

            I'd consider doing a single motor/drive config-- less stuff to go wrong, a lot cheaper-- and you can still hit 50mph pretty easily.
