    MHZ Mystic 114 - my first proper build

    Hi everyone,

    after a lengthy debate mostly with myself and by guiding from Manuel I made a choice between HPR C5009 and MHZ Mystic C5000 114 and picked up the later from MHZ christmas sale. The biggest reason behind was having a hull that can handle well in turns and that there was a topnotch thread covering the build process (thanks to Kent for that). I hope that Kent won't mind as this build will be quite similar as his was because it was the inspiration to build one of these cats. My goal is to have a cat that will have reasonable speed, good handling and as long runtime as possible. I've planned to start with octura x442l/r and 6s lipos as those are what I got and take it further from that.

    The hardware I currently have:
    Mystic 114 hull
    2x 4082 1600kv leos (had one of these previously)
    2x Seaking 180A escs (same as above)
    drives from MHZ
    carbon parts also from MHZ
    custom made rudder from Manuel Wenny
    hydraulic rudder steering from MBP-rc
    +other bits and pieces

    The build process won't be fast as I'm having quite a long to-do list and want to spend time with my wife and 5 months old son, but most importantly, waters are still frozen for 3 to 4 months here in Finland.

    First problem came up today when I got the drives from backorder. The shafts were different lengths and one of them was a bit larger diameter at the flex end and was binding and not rotating freely. I hope this will clear out well with MHZ.

    I was lucky to get the custom made rudder for the hull from Manuel (thanks again Manuel!) as that gave me the chance to use working hydraulic rudder steering rather than to just use a mockup besides push-pull system.

    Wish me luck, chime in comments and suggestions as here I go!

    You will be very pleased with the outcome as long as its built correctly. You cant go wrong asking kent and manuel for help either. Both of kents mhz's were top notch builds , and manuel is very very knowledgeable as we all know. There are also many other people who know a great deal about what it takes to build a great running cat. Good luck with her and if there is anything I can help with please ask. All I can say is take your time, read as much as possible, and ask questions. I have a hpr06 build that may help a little here on ose.

        Hello, I feel all special now its an awesome hull!!! I have all templates for mounting drives if you need them?? this is definetly the right hull if you like a nice look. don't be afraid to ask as many questions as you need. the only thing I would change is the 1600kv motors to 2200kv on 5s or 6s. Today I got 80mph in my "OLD" HPR with that same setup. If thats enough then cool!!?? but you cant expect to go a lot faster, maybe with 450\3 props, I was running 448's and everything cold as!

        @ Phil, Hows everything going???....long time no hear. How's "My Boat going" ?? I always wonder...

          Agreed with nata2run. It is cool to stay conservative when setting these boats up but come on man you've got an MHZ mystic 114 lol. I would go with the 2200kv leopards or maybe step down to the 2000kv if you're running 6s. The esc can take the 2200 but its pushing it. I have run the seaking 180/5s/1600kv leopard 4082/x447 in a 42" MHZ boat and it runs all day, its fool proof. Have some fun and try out the 2000kv motors, if you have the itch go for the 2200kv you won't regret it.

            Yup 2200 is the ticket but if you've got the 1600 and wanna stay In a budget with motors that's fun too. You can always swap out if not fun enough.

            @ Nata
            Robs boat is great he ran it a few days ago. I still haven't seen it run. He's scared of her lol.
            Wants me to drive says the steering is very touchy I'm thinking dial down the % on servo but ill have to try it first may just be him.

            Mine hasn't seen water since it left the water at 87 mph on 5cell with 445 3 blades, took to air off a cross wind and I needed a pilots license for 2-3 seconds. The batteries broke loose and did some damage Inside but alls fixed and reinforced.

            @titu if I can stress one item it's secure the trays more than you think, 6cells are bricks and will damage interior if loosened. Look into rail system.

                    Hi again,

                    thanks to everyone for the tips, suggestions and advice. Regarding the motors, most of the builds I've seen have 2200kv leos (if using leos at all), but as I got already one 1600kv, thought to start with those. Hadn't planned yet how the batteries will be mounted, but I'll take heed of the advice when the build comes to that.

                    @Kent: and I thought I'd be happy to get 60mph with long runtimes based on my previous boat , so if the 80mph is achievable with the hardware, that suits me perfect for now . Thanks also for offering the templates for the drives, but it seems that I have to do my own template as MHZ have changed the drives a bit from the image on their webpage. As for now, it's fastened only with two bolts to the transom instead of three and it's shape is a bit different too.

                    Managed to make some progress with the project during the holidays. Nothing much though, but got the rudder mounted along with the steering equipment. The rudder's build quality was excellent and it was a direct fit to the hull. Mounted three brass tubes through the hull and epoxied them with some fiberclass to the hull, should be sturdy enough for my needs. Only thing I modified in the rudder was a little cap to cover the top end of the rudder's shaft. The hydraulic steering was easier to install than I thought and seems like it will work like a charm. I'd think I'll got around 30-35 degrees of turn to each side. Time will tell if that's enough.

                      Looking good man !!!! I think you should have more than enough travel for the rudder movement. I use less than that on my hpr 06 I am assuming it should might be the same for your MHZ, but kent or manuel would answer this better than me. Keep up the nice work

                        Quick question before I drill the holes for drives: should I reinforce the transoms with some cf-plate? I'd rather do that before (if necessary) any drilling. Tried to loof for it, but I think Kent didn't do that on his build though I might be wrong.

                          Do it before if you want to install it. You don't want to risk gluing in on an angle, so best is to mount then then glue in all together with some thickened epoxy, and grease on the drive/screws so it don't stick to that part.

                            Yup grease or vaseline works great to keep epoxy off of things you don't want to get glued in.

                              Titu, nice built I bought a Christmas pack from MHZ in 2011 and did today my first little run.
                              The boat is very cool and nice in the corners.
                              Still some trim work to do but it was a good run.
                              Good luck with your building
