        It might just be me? But in picture #4 your drives look kind of far from the transom bottom

          Why did you mount your drives so high , as low as possible is much more effective for a twin mono.
          You can run smaler props wich give a more steady drive and in turns the outside prop is not lifted so much.
          Here is an example how most drivee are fitted

          Keep up the good work you are on a good pase.

              I know the wd200 drives.
              I am planing the mtc struts, strut holders and 20 mm extention blocks , they work simular but are a little less bulky and are lighter.
              Here are some builds i also used them for.

                Hi Jason

                the drives are mounded 10mm up from the out side bottom as this is the core thickness. they are at 100mm centres which after toe in will be around 90mm which will allow me to swing up to 80mm props with 10mm clearance (plan is to make a tie bar when i have time) as I can have an easy 10HP to absorb if i want to. the drives are also are 175mm long with the prop starting at 145mm after the transom. much like a real boat the water will have risen at that point making the height less, so should in theory actually keep the drag down. another plus side is that I can easily undo the required to extract the stub shaft as and when is needed.

                Hi Ramon,

                i will try and get some pics of the rudder mount, i mocked it up out of foam and then we are milling it at the moment, had not seen that rudder that is on the other forum befor, but it is similar to that, accept the taper runs from deck height down to a mounting plate and it is longer, to get back behind the props.

                i will keep the pics coming if you want to see them, but the build is unfortunately going to slow a little after this week as its now getting very busy at work.

                  hi!

                  made up the water pick up from s/steel, polished and welded....haven't decided what i'm going to do yet, either split the two into four and cool ESC's and Motors seperatley, or keep it as two and run them in one system for each side

                      Aren't you worried about the amount of drag that pickup is gonna make? Generally it only takes a very small portion of the tip of an angled tube in the water to make plenty of flow. Maybe it's the way it looks in the pic, but they look buried, are they adjustable?

                        Hi Heaving Earth,

                        not too worried about the drag as at first I want to make absolutely sure there is plenty of water flow.so i can test everything one by one with out worrying about everything the first time it hits the water. when it comes to tuning them, they are adjustable in as much as I can easily cut off in small increments as I need, (easier to cut off than add on )

                        also want it to look some what realistic

                            I think those vents may come back to bite you.

                              Water always finds holes in boats. Gas boats will let you get some water but never electric. looking at the boat that your using as a blue print shows great handeling in ruff water due to the added weight that was done to make it water proof. I would not have went down this path myself. But it is a nice boat and yours is looking to be also.

                                Hi Rumdog / twissted

                                i'm really not too worried about the water getting it as I think with a plate on the inside of the hatch one, it is the same as not having a vent in at all, and the aft one will defiantly have box with drains as a minimum, but due to the potential crash issue (i have now seen one roll on you tube) i will probably put the carbon fibre plate on that too.

                                on another note, also due to the slipping out I have seen on occasions, I have decided to mod the MHZ trim tabs and build in ''turn fins''

                                whats your thoughts?
