    I decided to test a theory, so I've modified my MG to have an offset rudder, using the stock pieces, two spacers, and two long 10-32 Titanium bolts I happened to have.

    Basically, I drilled out the stock holes on the right side strut bracket, and center piece, to 13/64", and drilled and tapped the left bracket to 10-32" threads.

    I then cut the rudder standoff as shown, and used the extra piece as a spacer in the strut bracket to help it maintain it's rigidity.

    Opened up the holes in the rudder bracket and countersunk them, and bolted it all together. Bent up the stock rudder linkage to fit. Solid and fully funtional. Doesn't currently allow for adding/removing castor from the rudder, but for now it'll work.

    I'll try to get out this weekend and give it a test to see if it's better, worse, or no difference.

    I suspect that the HOR hull is quite a bit different design. Is it fully stepped? If so, it's not the same at all.

    I'll let you know how this works out. If it works, then I'll clean up the spacers and polish them, and likely through-bolt the bolts by getting longer bolts so I can adjust the rudder castor.

            Ray... they are about 1.4" long... Not sure the OD... Large enough to fit over some 10-32 bolts. I don't think they need to be that large, as long as they have enough mounting area on the ends to support the rudder without allowing it to flex. This setup on mine is rock solid... Had to reverse the servo at the radio, as I moved the steering arm to the other side of the rudder.

                It's just on there as a mock up to test rudder clearance. That's an X450/3. Wouldn't recommend that one just yet...

                    For racing... the motor seems to handle the X447/R I use on my 1/10th scale just fine, so perhaps. But be careful and work your way up there.

                      Tested the MG with the offset rudder conversion today... WOW! Maintains it's speed in the turns, and seems to run very smoothly in the straights. Used and X447 for this video clip, with the strut slightly above the sponson bottoms. Still needs some tweaking, but I think that taking the time to offset the rudder is DEFINITELY a worthwhile mod, especially since you can do it with the stock pieces.

                      I think I may try mounting a second rudder on the left side and see how it works with duals. Likely to lose some due to drag, but still might be worth trying. Simple to do. Just going to fab up two more equal spacers, and use 10-32 all-thread all the way through both sides, then tie the two together using a tie-rod.

                      Here is a video clip I shot while testing it today. Forgive the crappy tracking. I was alone, so I used a microcamera mounted on the foot of my transmitter and tried to point it at the boat. Not used to tracking the boat that way, so I missed a couple of times.

                            Made a quick update to the rudder mounting. Replaced the titanium countersunk screws with some 3" Stainless 10-32 screws with stainless nylock nuts, and through bolted the entire assembly. It's totally solid now, and now allows the rudder castor to be adjusted. Polished up the spacers while I was at it.
