MHZ FOUNTAIN and CASTLE 1717 1580kV

[Alfa Spirit]

Because very low prices from Castle Creations I bought a 1717 1580kV motor and I' m looking for a deep vee hull capable to work with this motor.

MHZ FOUNTAIN 39" should be fine with 6S 1P or 2P batteries, what do you think guys?

Technical Details:
Length: 980 mm (39 inch)
Width: 215 mm (8.5 inch)
Weight: 745 g (26.3 oz)

[forescott]

I think it will work fine with a smaller-ish prop. Definetly 6s2p. The new 200amp LV esc that OSE will be stocking in the next couple of months should work well with this motor too.

[westbeach]

Alfa,

That is a very nice hull, looks like you and Jesse will have to have a build off, if you both end up getting the same hull. :bounce: I'll be watching closely. :buttrock:

Ya baby, you know what they say about great minds, cheap Castle motors and sweets boats... Alfa, I hooked up my 1717 to the water cooled outrunner motor mount I got from Williams Racing and it fits perfectly, you could get one (be sure you get 25 mm bolt spacing) for a little cheaper that isn't water cooled - probably don't need it.

I don't have my hull yet, but will start me a build thread - will be great to compare notes as we go. Yep I was thinking 6S2P and 45-47 mm prop - probably won't be able to go much more w/o heat issues.

[westbeach]

Jesse, how soon till ya get the boat?? Any ideas on harware? Scale drives??

[Brushless55]

looking forward to this one :thumbup:

[JEDNJONES]

I might have to copy you guys too. I just cant find a realistic stepped Fountain anywhere in this size range. So...Dragon Lady is looking good for a winter build. Anxious to see wich drives you guys are going to use.

[Alfa Spirit]

I will run this Fountain 39" hull with this setup. Trimax is great and expensive :tongue_smilie:

That is very nice hardware, but the dumb twit that I am , explain how it functions.

Douggie

[forescott]

The flex shaft has a square end that slips into the square female end of the black propshaft, which in turn slips into the stinger from the rear. Stock hardware from the HK osprey!

Nice hardware here, MTC https://www.mtc-powerboat.de/index.php?lang=en&section=13&produkt=6&variante=83

[CornelP]

Douggie, the main idea here is that you can adjust the strut in 2d instead of the usual 1D. Decent thing if you want to get rid of some of the torque effects... but then again you can offset the strut from the beginning...
Anyway, Trimax and MTC are usually designed for gas boats, so big wires...

[JEDNJONES]

Wich size Trimax is that? I dont see that one on MHZ w/ that brass fitting on top. I am tossing around the idea of twins in this thing. Those SSM#6 drives look awesome but are too big and expensive.

The hexes on each of the three rods are threaded left and right hand thread, so you can lengthen and shorten the rods by turning the hex (without removing them). By turning the hexes you change the rod length and in turn change the strut angle.

Is that what you were looking for?

[JEDNJONES]

Guys, I just spoke with Lowe at MHZ and I want a white hull. He has yellow in stock and is willing to shoot a batch of white if he has enough interest. Can you let me know if you guys are looking for white Dragon ladys?
Thanks,
Jerry

[Heath M]

This strut would look good as well http://www.mddracing.com/Home_ban_Ls.htm click on hardware

[Alfa Spirit]

The Castle 1717 arrived in France, MHZ Dragon Lady Fountain should be at home at the end october :w00t:

I was looking to MHZ Racemaster but I really like de Fountain design, what do you suggest for the rudder: center or on the right side? Or may be two rudders?

[Alfa Spirit]

What do think about MTC PowerTrimm V for the Dragon Lady hull? See attached file
Length = 90 mm / 3.55"
Thank you

[westbeach]

Alpha,

The MTC powertrimm V is very nice. I would invest in one if they were easy to buy.

[Alfa Spirit]

Yes westbeach this is a nice part, price is double than a chinese stinger. I don' t know if the lenght is correct for this hull

[westbeach]

Alpha, yes the pwertrimm is too short for the fountain hull, you need at least 10cm length for the fountain like this https://www.mtc-powerboat.de/index.php?lang=en&section=13&produkt=1


Yes westbeach this is a nice part, price is double than a chinese stinger. I don' t know if the lenght is correct for this hull

[Alfa Spirit]

The difference of lenght between those 2 parts is only 1cm. I' m not sure this is important, this centimètre is expensive :laugh:
Lenght of stinger is approx. 10% of hull' s lenght, is it right?

How many rudders? One or two,

[Alfa Spirit]

The motor arrived, it' s big and magnets are very strong, a nice motor for low price, good deal

What is the lenght of your Outlow? I will run the 1717 with 5S 2P parallel

[Brushless55]

The Outlaw is 39" and I'm going to start with 5s2p, then get some 6s packs and run 6s2p..

I just got done installing my 1717 in my 40" fountain Vee!

I think bigger?
I have the stock S225 on my Outlaw that I will keep on it when I try my 1717 on 5s and 6s

[Make-a-Wake]

Maybe so................i was wanting to start on the small side..........check temps etc.............and work up. It may well end up being a 445, 447 or s225............thanks.

[Brushless55]

I hope to be able to go upto a S230 and possibly a S235

[Alfa Spirit]

DISAR build a MHZ Racemaster, his hull is 1 meter long like the Fountain. A Castle 1717 on 6S will give too much RPM, I think 5S will be ok, around 30000RPM, 5S 2P (parallel) should be a nice setup

[Alfa Spirit]

What do you think about this hardware, lenght is 9cm ( 3,6"), is it enough for a 39" hull?
This hardware is expensive, If you have links to cheaper hardware that' s great :help:

[DISAR]

The prop distance behind the hull is one big question. normally is 10%, but when I asked MHZ for the racemaster they said 55mm which is quite small I believe. I have it at 85mm and I use the eco trimax but I think that the speedmaster stinger is far better. I recommend the speedmaster stinger, very good quality, 83mm length and cheaper. 3/16 flex, teflon and 9/32" tube. the teflon just fits in the stinger very nicely.

If you want longer distance you can install a distance piece on the transom or elongate the stinger, but need to find out how ...

[Make-a-Wake]

I guess the 442 was too small, took my first run with my 40" fountain with the 1717 on 6s. Ran very well.............not a huge speed difference from the Feigao 580L but definately faster.............the thing is though, the 580L would come in at 125*, and the ESC fairly warm too. This motor came in after a 3 minute run at 78*..........yep...........78*. ESC was 83* and caps 89*, its a Seaking 180. This big boy wasnt even loaded up and i imagine that loading it would wake it up. I think the s230 mentioned by Brushless55 would be a good fit...........that or an Octura x447. I'll play with it.................

[Rumdog]

That motor will spin a MUCH bigger prop!
Good luck with the Seaking on 6s though.

Bam!
this is very awesome, another great run on the 1717!
let us know how the S230 or the X447 run. I will buy a prop for my OSE Brothers Outlaw after you run yours :banana:

do you have a cooling jacket on your 1717?

Are you talking about this 3/16" Speedmaster Stinger Strut? http://www.offshoreelectrics.com/proddetail.php?prod=ros-stinger-str

What 3/16" prop shaft and what 3/16" flex shaft work fine with the Speedmaster Stinger?

Thanks

[DISAR]

Alfa yes, this stinger, I believe that you have all the items needed for the shafting.

[Alfa Spirit]

Thank you for your help DISAR, parts are on the way;

The Speedmaster strut for 3/16'' look fine, What about the lenght 82,5mm?

[K.R.Joye]

Not sure if you seen my post on RR this is my current setup with uncooled 1717/1580

40" AM Sprint Cat

Etti HV 200 amp water-cooled ESC

6S1P 30C 4500 Lipo

X450/3 Prop detounged / 53MPH GPS no heat on anything

X452 Prop detounged / 57MPH GPS no heat on anything

I'm likin these motors!

[Gerwin Brommer]

Alfa :

The Speedmaster Stinger is even better than the others.
Why ?
You can adjust not only the angle, but also the HIGHT of the shaft !

Lenght : 10% is not a "rule".
Works well on stepped mono's with a SAW-setup.
For a normal setup/hull you don't necesseraly need 10%

[Alfa Spirit]

The Castle 1717 with his water jacket is a monster, great !!

[Alfa Spirit]

Parts of hardware are on order The flexshaft and the coupler come from Dave Marles, out of stock at OSE

[Make-a-Wake]

Have this hull on the way for my Castle 1717. The old hull wasnt performing to my liking. Gonna run it on 6s............its 39.5".

Question is, which prop? I'm thinking in the x445, x447, x642, x645 range. Any suggestions are very welcome and appreciated!

Looks like my Thundertiger OBL :thumbup1:

[forescott]

I think the x452. Those props are kinda small for a hull that size. I ran the m545 on a castle 2200 with no heat issues. The 1717 will push those props without breaking a sweat!

[Make-a-Wake]

OK...........seems kinda big, but thats why i asked. Thanks!

[Alfa Spirit]

I need help guys, how many rudders for the MHZ Fountain? I think that I will install two rudders for stability, what do you think?

[DISAR]

OK...........seems kinda big, but thats why i asked. Thanks!

If it is the thunder tiger OBL, it can do well with small props as well. I ve seen one with a prather 220 and a 642. Depends on the position of the strut, if it is low small props can work, if it is high you need bigger props.
Depends also on your esc, 225,230,445,645 are definately safe, then if temps-amps are ok bigger ones can be used

[Make-a-Wake]

Thanks DISAR................ got my hull in, got all the parts too.................just gotta pace myself as i tend to wanna rush things a bit and i want this to be as close to perfect as i can get it.

Not trying to hijack your thread alpha..........we both have 39" mono's with 1717 power and i thought id share mine as well.:smile:

I think I' ll use 2 rudders for my MHZ with a symmetrical assembly and water inlets

[Alfa Spirit]

Nobody? :confused1:

[DISAR]

why not buying the twin rudders set?

to be honest I don't know if twin rudders will add stability.......?

[Alfa Spirit]

Twin rudder sets on Ebay don' t have water inlet.
The Speedmaster stinger is 115mm long with the DD and the propeller, this model should work :confused1:
If the rudder is to long I can cut it, water inlet is high, but I want to know if a symmetrical mount is possible

[Alfa Spirit]

I' ve got the answer :banana: :rockon2:

Speedmaster strut, flexshaft and coupler. Speedmaster is a nice part :thumbup1:

[Alfa Spirit]

Total lenght of the Speedmaster strut , drive dog and flexshaft is 120mm

[DISAR]

I was looking around for twin rudders as well and now realized your point...........

You were referring to the brackets arrangement, so it is possible.........isn't it? Are you going to use two servos or one servo and interconnect the rudders? how?

[Alfa Spirit]

Exactly, it is possible with those rudders from Promise Hobby they are symetric, only one servo with good linkage

[Alfa Spirit]

I will interconnect the rudders I' ll see how to when rudders will be at home. May be a U inverted part aluminium made fixed with up screws

A three blade prop i think x447-x646 on 5s 2p.
I realy like that hull for salt water.
