72" mystic power

[JKArcade]

So, I'm new to the site and new to large scale boats. I bought a new 72" mystic hull from central marine rc and am building for pure speed. I am looking at the leopard 56110 780kv for power. It looks like 12s a side is what it can handle. Anyone have experience with these? Also, looking for an esc suggestions and props. Going for a higher end build.
Any suggestions would be awesome.

I'm guessing you'll be running this at LOTO?

For efficient, reliable and let's not forget expensive, high-speed running of your boat...nothing will come close to a Lehner 3060/8 (875Kv) and MGM 40063's controllers. Of course it's alot of cake for that setup, you could probably get away with MGM 25063's with cap banks and more conservative props (X457's) but will be on the edge of that esc's capacity, esc headroom is important on such a beast. If that is not in the budget then think about a large set of TP motors like 5660 760Kv. More affordable esc's: Swordfish 300 or possibly a Flier 400, I have a set of those in my 54" Mystic and so far so good. It's obviously a huge boat and going to weight 40+Lbs when loaded with 12S2P/side, expect 4-4.5 minutes of runtime only! With the Lehner/MGM setup you'll easily have the power to blow way past 100mph with a prop like X470 reduced to 60mm but the thing is, you greatly risk horrific crashes on anything less than perfect water...and with all that money in motors/esc's it can be a really bad day. The bigger the boat the harder it hits. What kind of speed(s) are you looking for anyways? If running in the 70's and into the 80's is fine then you can save alot of money on your components but you won't have the option to hit those higher numbers "when" the need arises...but nothing wrong with running those speeds, more runtime and less chance of losing the boat in a crash or blown esc's.

Looking forward to seeing your build and progress!

There's a few bits of setup info on big Mystics here:

I live in Kansas City. Will run around here mostly, but might run to the lake here and there.

Thinking of doing a duel setup. One for play, slower more reliable speeds, then saving and swapping to a second setup when the need arises. Ultimate goal is 100mph+. But seems like a bad place to start. 75mph on setup 1, 100+ on setup 2.

Your hull literally requires a dual setup, don't want to open a can of worms here but a hull this size needs alot of juice and two motors working together is just more efficient plus with counter rotating props you get rock solid stability and no leaning. Also, you could easily accomplish both speed goals with one setup, just dial in cell count and change props. My Mystic will run endless 90-95mph in the straights while running a massive oval on 8S/side and X457 or ABC 2215's, add two more cells/side (10S) and speed jumps to 105-108, throw on the X470's and she'll stay on the water at just over 115mph with room to go, it's a very versatile boat/setup. Of course I could run smaller props like my reduced (50mm) X457's and add more lipo's in parallel like 8S2P/side and would be in the 85mph range for close to 10 minutes. Changing motors seems easy enough but it is actually quite a pain unless you really love this sort of thing. Personally, I would not "swap" anything just to change speed other than the cell count and props, put your hard earned money into the best motor/esc combo you can, it's a hull that is certainly worth it and not the sort of hull you want to cut corners on, not saying you are/would ;-) Again, just my .02

I have no thoughts of running anything but twins.
Is the lehner worth it. Seems to be the best. Could do like you say, set it up and just dial down the voltage. Which esc would be good with the lehner? I don't mind swapping setups, but makes sense to leave motors and swap props and batteries.

I only mentioned about your hull "literally requiring a dual setup" because it sounded like you were "thinking" of doing a dual setup...just had to check ;-)

Is Lehner worth it?...this very thought has gone through my head many times while trying to make the same decision that you are trying to make. I enjoy all my boats whatever they are powered with but to me there is something a little bit more special about a Lehner powered boat, in no way am I bashing any other brand, there's alot of really great motors out there but once you step into a hull your size the power of a 30 series Lehner really allows the hull to shine, if you want to see the limits of your hull there really is no other choice but maybe that doesn't matter. I've truthfully never regretted the extra costs involved with Lehner, yes you will still be happy with any larger motor that will make your hull move but I can assure you that pulling the trigger on a huge dual Cat with dual Lehner's...pure adrenaline!! I've got a few Lehner powered boats, they feel like they move the hull in such an effortless way, they feel comfortable, predictable, responsive and run cool (with the right setup) in such a wide range of speeds keeping in mind this is running with quality esc's and lipos.

For esc's, same goes, big boat needing big power, MGM but painfully pricey. I've had moderate success with Swordfish 300's but lost many to the magic smoke for reasons that made zero sense, in your hull I'm not really sure I would trust them unless you were keeping the props smaller, maybe they will be fine, maybe not, under full throttle you will be under the limit but on launch that hull is going to pull huge amps while getting on plane and that's when things can (and probably will) go POOF!...and most times it's a meltdown and non-repairable. The Flier 400's are showing promise but again, I would not trust them at this point in a 72" hull. The Swordfish and Flier's are not exactly cheap, risking $600 in esc's when for twice the price you could get top quality MGM's and not worry (as much)...worth it to me. There's a reason you mainly see these big hulls with either old school Schulze's or MGM's. Really, the choice in esc seems to be the big one, it's always the weak link, the MGM 40063's while very expensive will most definitely provide the best all around experience. I'm sure you knew what you were getting into when you decided on your hull, there's no easy way around it but when the day comes that you pull the trigger...well just wait and see...and the extra expense will seem irrelevant.

I hope something up there helped, if not I'll try again tomorrow after the caffeine has set in ;-) BTW: My 40063's are due to be delivered to me tomorrow (will post some pic's)!!

This helped a lot. I'm going to get my pricing together for the lehner setup and make that choice pretty soon. The point of this build has always been higher end and fast. Might not be ready for spring time, but it'll get done.

When it comes to motor wind, there is an option from 4-40 on the lehner 3080. Also, high amp or LK? Any suggestions/thoughts there?

[Lone-Wolf]

I would go with the LK motor, a little extra cooling doesn't hurt, it's what I use for what that's worth. Yeah the 3080 of course would work but at this point you're just adding more weight, won't be a huge game changer, seems the 3060's are what works in the 72" hulls while the guys with the monster's (HPR233) are running the 3080's. For sure the 3060's will provide all the power and then some, easily enough for the 72"...heck the smaller 3040 would be fine too I'm sure!

Attaching some shots of my newly acquired MHZ185, this is what the MGM 40063's are for...was going to post a thread on the boat soon but since we're talking about 72" hulls I may as well show you something that will surely help in your decisions.

That's nice! Gonna break the toy bank for a bit, but seems like the way to go. What motor wind would you suggest?

[JKArcade]

Where did you get your MGM's from?

[Lone-Wolf]

Yeah the paintjob is unreal, total eye candy. Has the extra layup in hull and hatch which is nice, MHZ's are flimsy otherwise. Mine has the 8 turn and seems to be perfect for 12S. I'll be pushing the hull starting this week and will really know what's up shortly. Uploading a video now and will post momentarily...
