    Carbon shocker build

    I've been having this for quite a while. I started on it a while back and it's almost done but I never started a thread on it. It's not meant to be a blingy type boat....just fast, cleanly laid out and strong. Here's the plan:

    Neu 1530 (on order, 1527 for now)
    8s
    Mbp collet
    .187 flex
    Sf300 lite esc
    Custom motor mount sides
    Custom cnc battery trays
    Bby racing fiberglass canopy for gps runs
    All hardware on the outside courtesy of speed master
    Grossly overpriced spektrum servo that was given to me lol
    Integy billet servo arm (I love these things!)
    Honey comb carbon inlay

    Here's the beginning. This is the part that I absolutely hate! Sanding and then doing an inlay. I'm afraid I won't get it straight one day and I'll have to rip it out. It's gonna happen. I know it.



    Inlay turned out quite nice I must say...





    And in an attempt to get as much as I can....I went as far as I could....



    Trust me it wasn't easy following all these curves.

      So I had my buddy Monojeff cnc cut me some battery trays and longer side plates for the motor. The 1527 and 1530 neu's are pretty long motors and I thought it would be better fitting to support them more towards the rear. The trays were a big help and time saver too. All of it came out perfect!






      Kind of a mockup just so see how things will fit. I have a couple different power setups that will be run in it.

          So I just could not make up my mind how I wanted to do the esc mount. I still haven't. So I make this for now and I just siliconed it in so I can change it up later. But this is what I have for now...
          O and the motor mount is in....

              So the transom seam pretty much sucked. It did not line up worth a poo. Pretty much the norm it seems with tenshock made hulls anyway. Yuck. So I block sanded it flat and then put a coat of clear west systems epoxy back on it to seal it. Much better. Not sure if you can tell in this pic....

                  This is the original strut I bought from speed master. It's a .187 stru and I was going to drill it for ball bearings. I chucked it up in my lathe and the way it's machined, the hole would not center. I only have a 3jaw chuck so I'm ass out there lol. I ordered the 1/4" version which just so happened to fit the bearings perfectly.




                  So here's the 1/4" version. I was able to devise a method to cut a snap ring groove. One of my customers had his bearing come out with me using just loctite so here's my solution for now on. I've since machined his strut too free of charge so he no longer has that issue. I don't like problems!

                      Here's the strut bracket mounted up. I was so back and forth on the hardware I was going to use. I didn't want an offset type strut assembly because at low speeds the bracket drags and causes a pull. I decided to do something different that I was used to, use a seperate rudder and strut mounted in different locations. Also I've been using mostly tfl hardware. While it's decent stuff, it has lots of slack that's more work for me to remove it. Monojeff sent me a speedmaster rudder and I was amazed at how much better the quality is and has noooo slack and smooth as silk. That's what I'll be using when I can for now on!



                      Here I had to mill a half moon in the bracket for my linkage rod to pass through and line up. I wanted as straight as I could linkage rod...

                          Mounted the rudder. Had to machine a fitting for the rubber boot to go on. I also am trying something different on the linkage this time. I want no slack whatsoever so I ordered some very hard 1/8" stainless rod and turned the ends down a touch so I can thread it for 4-40 heavy duty rod ends. This setup is the stiffest I've done yet.

                                  Thanks. I'll post some more pics tonight. I didn't have any current ones.

                                          So I have no idea why I did this other than its ugly and I needed it waterproof lmao.

                                          Here's my hv bec unit encapsulated in epoxy and topped off with a .010 piece of carbon





                                          Wires and cooling line run. Servo in place. Getting close.

                                              I think I'll make the servo cross bar out of carbon. Too much aluminum going on around the servo. Getting even closer. Getting everything hooked up.




                                              Here's the pass through for the flex tube. I'll touch it up with some black epoxy for looks.

                                                  Back end pretty much assembled. I need to make up the flex and a couple little odds and ends and it'll be ready.

                                                      I was very much on the fence about going with Teflon liner or not. I figured the little bit of friction reduced by the Teflon would be offset by the bigger diameter tube dragging in the water (.316 vs .250) so I opted not to. I kinda wish I did tho because it seems like I'd have a less trouble free driveline. I guess maybe next time.


                                                      So I'm still on the fence about the esc mount. Maybe it don't look too bad with the esc in it. Any idea on what I could do to dress up the esc? I thought about copying the decal (deleting some unnecessary wording) with a green decal, apply it to a carbon plate and attach to esc. Thoughts?

                                                          I would tuck it under the deck farther and use nylon or CF braid on the wires. Snazzy enough? Just a top of head thing bro.
