    I see people saying the offset servo horn is best like the one from custom carbon fiber parts. Not who else sells one like that.
    I don't trust the tiller-arm locations, that are not in-line with the pivot. Hence my making of the rudder blade grip.

    I'm using a black aluminum fut25t servo horn.

    Faux hydraulic rams will be used.

    Countersunk bolts arrived. Rudder done:

      It's best to keep everything linear and the attachment points inline with the pivot at both the rudder and servo. Makes life so much easier.

        I want flush fasteners on the rudder blade-grip, so I turned down some flanged nuts, to suit my tastes:

          Looks clean. Anyone know the spacing between the rudder pivot points on the stock mounts? MHZ does not specify and I want to order a servo and servo horn for it.

            Do you mean the distance of the tiller-arm holes from pivot pin? If so, I will measure them tonight after work, then let ya know.

              Correct, I see most in picture are using a small horn like this cheap Amazon one 3Pack ShareGoo Aluminum Alloy 25T Servo Horn Double Arm Steering Arms Compatible with Futaba Savox Power HD HSP MG995 Servos Motor 1/8 1/10 RC Car Buggies (Red) https://a.co/d/dIHTr1c

              I just want to confirm before I go buying anything.

                Ha, I've never thought of doing that. Great Idea. What did you use to make your counter sink holes in the carbon? I used some cheap habor freight drill style bits for wood, but they dulled after a single hole. I need to find an aggressive cone shaped bit for my mill.

                  One of my best tools. Carbide multi-fluted counter sinking bit. Made in Chine off of Ebay. It's now slightly dull after about 15-years of use.

                  I have it in a Hudy handle, and turn it by hand.

                          It's coming. Did some reinforcing in the hull & deck today. Thickening up stress-areas and bad lay-up sections. Rough areas were mudded, and will be sanded to make a refined surface, as well as feathering out of the seam edge. Then, 1-layer 6oz. carbon cloth will cover the entire inside.

                          While the hull & deck are apart, I'll be rigging it. So much easier like that. Reminds me of my full scale boat building days, crane-lowering the engines in place etc.

                          Just had the angle-grinder out:

                              I appreciate the offer but it would cost us more in shipping than me just ordering it on Amazon. Canada to South Florida isn’t cheap. I ask because I see most of the fancy mystic builds use the CCFP servo horn which looks nice. I want to avoid cable slack when in turns. Also Oxidean sells a cheaper version: https://www.ebay.com/itm/22545883823...mis&media=COPY

                                Hulls looking really good, you are invested at this point since you sliced it open. I see not short cuts being taken, you are doing the right thing. I really hope I don’t have a similar issue with my assembled 114. With a 3 month old baby I just don’t have the time to do that kind of work. I don’t like to half a** anything and I knew building a bare hull would just send me down the quest for perfection rabbit hole. Any free time I have needs to be spent on the water at this point in my life.
