[bbosncali]

Ok so finally after a week I got my mg today... I've been sitting on all these upgrades now let's put them in... first off thhttp://i1094.photobucket.com/albums/i446/bbosncali78/2011-03-28144943.jpge hull looks awsome very happy with it

[bbosncali]

Stock electronicd time to go... enjoy brushless there yours....http://i1094.photobucket.com/albums/i446/bbosncali78/2011-03-28150633.jpg

[bbosncali]

Wow what a difference in motor size!!!! And yes thanks to everyone you have to cut the shafthttp://i1094.photobucket.com/albums/i446/bbosncali78/2011-03-28152325.jpg

[bbosncali]

Here's all my goodies I've been sitting onhttp://i1094.photobucket.com/albums/i446/bbosncali78/2011-03-28151537.jpg

[bbosncali]

Next was time to install the hobbywing 150a esc.... it had 3 cooling lines but decided to add a 4th to be safehttp://i1094.photobucket.com/albums/i446/bbosncali78/2011-03-28184212.jpg

[bbosncali]

Next it was time for the leopard 4074 2200kv motor and water jacket...http://i1094.photobucket.com/albums/i446/bbosncali78/2011-03-28205139-1.jpg

[bbosncali]

Now its time to install the kinetic offset rudder version 1 (they were out of v2)http://i1094.photobucket.com/albums/i446/bbosncali78/2011-03-28191427-1.jpg

[bbosncali]

http://i1094.photobucket.com/albums/i446/bbosncali78/2011-03-28184233-1.jpg

[bbosncali]

I installed a 4 cell aa battery pack from radio shack with an on/off switch to make life a little easierhttp://i1094.photobucket.com/albums/i446/bbosncali78/2011-03-28205400.jpg

[bbosncali]

It was a tight fit but everything did fit with plenty of battery room... fianlly my octura x642 prophttp://i1094.photobucket.com/albums/i446/bbosncali78/2011-03-28214431.jpg

[bbosncali]

And last but not least can't forget my trusty flysky 2.4ghz $35 remote.... what a steal!!!! I love this thinghttp://i1094.photobucket.com/albums/i446/bbosncali78/2011-03-28205445-1.jpg

[bbosncali]

Ill take it on her maiden voyage this week and post video mg vs spartan here I come shaun78 lol

P.S. thanks for everyones help and those of you I bought some parts from couldn't have did it without you!!!

[dana]

im running an x442 with my MM that has leopard 4070 2200kv. others with that motor in similar hulls tell me they got slower speeds with the x642 than with x442. if you have a 442 i would try that first

[bbosncali]

I have a prather s220 that I'm gonna try after a few passes with the x642 but a 445 is in the future not sure about a 442 though

[Brushless55]

Awesome Brandon!

I wonder why they say the X642 is slower? seams like it would be faster with the extra pitch :confused2:

[Boomer]

bbosncali
Nice choices. Your tests will lead you to the best prop choice. Just a suggestion,
you are running the 1st generation Kintec rudder off set. I think you will find the the lower section of the bracket drags in the water until you are running at at least 3/4 throttle.

That is the primary reason Kintec modified it - I have posted a picture of the 2nd generation bracket and a drawing showing in red the portion of the bracket that has been removed.

I suspect, like many of us, especially with the upgrades you are running you will find the the off set bracket is not necessary, and that shaft angle trim is the key :to proper trim and eliminating any of the MG "bounce." Be sure reinforce your canopy and tape it in place.

Enjoy
Boomer

[bbosncali]

What works for some doesn't necessarialy work for others.... imo

[bbosncali]

Nice diagram..... I may just cut it out that's basically the only difference.... we'll see how she runs I'm looking to hit mid 40's and ill be happy untill I bump up to 5s then 6s ofcourse lol

[bbosncali]

Kintec hatch lock mod...http://i1094.photobucket.com/albums/i446/bbosncali78/2011-03-29011650.jpg

[Shaun78]

not bad, time to upgrade the spartan, can have the MG beat me.....Looking for possibly 60 out of the Spartan when I'm done. Not sure but maybe a Leopard 4082 1500kv is in the near future and a HOBBYKING T-180. there I said it (take that traxxas moderators,lol)

[LarrysDrifter]

From what Ive seen and read,you better re inforce the hatch and add floatation to it before you take it out. Id add 2 layers of fiberglass to it.

[bbosncali]

I was gonna get a noodle and cut it and shove it inside the hull but I'm a little confused about what you mean by add fiberglass to it??? I'm not worried about the hatch coming off as those hatch locks make a very tight fit although I'm still gonna tape it

[JackBlack26]

Great looking MG. I have that same motor in my Genesis though I got the larger cooling sleeve that Steve sells. That motor can swing an x447 easily in the MG. I run an x445 in my Gen and everything is barely warm and it's a way bigger and heavier boat. Just make sure you run 30c or higher batteries. I run 5000mah, 20c packs when I'm in a pinch but they get a bit too warm.

I agree on reinforcing the hatch. Should of done that to mine BEFORE I broke it, lol!

[bbosncali]

Yeah everywhere I looked couldn't find the 40mm or 50mm everyone is sold out. I was lucky to find this through a post on this site or else id still be waiting... I will upgrade when they become available. What do you guys mean by upgrading the hatch and how??? I'm open to sugestions just not sure how to?

[JackBlack26]

Some of us who have had issues with the hatch have layed a layer of fiberglass over the inside of the hatch to ether keep it from breaking or to put it back together. I broke mine on a blow over but it was just shattered. I left the window of mine without glass cause I like the way it looks and the fact tht when the boat is speeding by you can see through it.

[LarrysDrifter]

Apparently,the plasitc hatch shatters in a blow over or wipe out in general. I was saying to add fiberglass matting to the inside to give it added strength so hopefully the hatch will stay together. One should always re inforce the hatch along with the hull IMO when building or buying a boat. It just makes it stronger as a whole and it will definitely last longer.Matting and resin can be bought at the local auto parts store.

[bbosncali]

That's a good idea thanks guys... it can't be a harder to do than say bondo or drywall mud... I would assume... oh and jb I'm running 2 2s 5000mah 40c right now and just ordered 2 3s 5000mah 40c so I can try 5s and then the crazy 6s..... so yeah deffinetly gonna have to do some reinforcement... you guys have some fast boats how do you keep it from the nose coming up and flipping over that's my biggest concern right now

[JackBlack26]

Glassing is easy. This is how I do it. Cut your cloth first to shape. Once you're happy with the coverage mix the resin or epoxy. Apply a thin layer of resin or epoxy to the area that will be covered. Lay the cloth and squeegee it in place making sure to move in one direction, usually outward to get any air tapped in to go out the sides. If needed brush more epoxy/resin until the glass becomes completely transparent. Done!!

As far as keeping the boat planted, move the batteries forward. I run my batteries from 9.5" from the transom forward and adjust the further forward if needed.....good luck and have fun!!

[LarrysDrifter]

Another thing to do is to add expanding foam in the front of the hull.Some dont like it,but if you get Great Stuff window and door foam and add it in small increments it makes the front end solid. To keep it from blowing over,move the center of gravity forward with the batteries.If you want to get an idea of the foam thing,look up my build thread titled "Triple Cat". For center of gravity ideas,look up my other build thread titled,"Larrys 32" Twin Cat".Im by no means bragging on myself,so dont think that.I just know you can get ideas from both threads.I also dont know how to link them or else I would do it for you.

[bbosncali]

Awsome.... thanks for the tips... I was going to use greatstuff but I've heard a lot of bad things about using. I used to build houses for a living so I'm extremely familiar with it and yes I gues if I just aply it in small amounts should be ok? How do you feel about making a ball of it so it expands and then cut the pieces to size that I need? We used to do that t fill holes we didn't want to blow out? Just curious if it would make a difference if I just stuck it in....

[JackBlack26]

Lary, find your thread, highlight the URL, press control and the letter C. In the reply box, press the "link" tab. Now press contro V and tht should paste the URL in to the box. That should be all you need to post your links.

[bbosncali]

Hey thanks for the tips guys I listened and applied and my boat ran great forgot to tape the hatch and almost zero water got in.... hatch nice and sturdy seemed well balanced with the battery suggestion the great stuff door and window foam was the ticket for me its non bowing... I wouldn't recomend the red can use the blue can it helps..... now if I can find the right prop for her. One that's already balanced cause that's a pain in the butt lol

[dana]

That's a good idea thanks guys... it can't be a harder to do than say bondo or drywall mud... I would assume... oh and jb I'm running 2 2s 5000mah 40c right now and just ordered 2 3s 5000mah 40c so I can try 5s and then the crazy 6s..... so yeah deffinetly gonna have to do some reinforcement... you guys have some fast boats how do you keep it from the nose coming up and flipping over that's my biggest concern right now

leopard 2200kv on 6s? you sure you want to do that..?

[bbosncali]

Why not?? ? Suposedly it can handle it? I gotta atleast try unless its an absolute no no

[JackBlack26]

It can handle it. Just run a 38m prop, 40mm tops.

[bbosncali]

Ok so don't try it with my 642 then? What's a good prop to run on 5s then. Not trying to break any speed records just want a little more oooommmmpppphhhh!!!!

[bbosncali]

Is a prather 220 to big to run on 5s with my setup?

[dana]

Why not?? ? Suposedly it can handle it? I gotta atleast try unless its an absolute no no

im curious to see your results. thats about 48,840 rpm... i dont think 6s is a good idea with that motor, but im no guru

[bbosncali]

Yeah that's what I came up with.... I'm pretty new to boats so I'm always open to suggestions

[dana]

i think youre gonna fry something, but go ahead and try if you like. just disable the bec

[bbosncali]

That esc has no bec. Do you think I would be ok with 5s?

[dana]

That esc has no bec. Do you think I would be ok with 5s?
you might get away with 5s, i cant say for sure. i was always told this is a 4s motor... you might search threads for the answers. i am running 4s on mine with a rather small prop x442 and i am trying to keep the hull in the water, let alone propping up. im nowhere near the speeds that can be acheived on 4s with this motor and the right prop so im gonna stick with props, and not more cells. jmo

[Brushless55]

4s motor depends on application
this small of hull could work but dang the rpms! the right prop is needed :thumbup1:

[bbosncali]

The esc can handle 210,000 rpms 2 pole 70,000 rpms 6 pole so that's good the 4074 2200 can handle 23vlts according to leopard

http://www.leopardhobby.com/product/product_veiws.asp?id=1323&functionID=01020207

[Shaun78]

i wanna see your boat on 6S too

[Shaun78]

if u cant run 6S then you will never catch me when/if I upgrade

[ron1950]

i know guys that run this motor in a mono with a 180 a esc and 4 cell and a m445 and they hull butt

[bbosncali]

I need to prop down to run 6s though so its not gonna be this week... need to find out about how big of a prop I can run on 5s. Besides your boat is gonna do barrel rolls if you put too big of a motor kinda like it wanted to today

[bbosncali]

i know guys that run this motor in a mono with a 180 a esc and 4 cell and a m445 and they hull butt

She was moving pretty good today with a x642

[Shaun78]

I didnt see the Leopard 4082 on that site

[bbosncali]

Does anyone know if a x642 is too big of a prop to run 5s on? Next question is why do you have to prop down with more voltage? If it can swing the prop now wouldn't more power be able to swing a bigger prop? That's where I get confused

[JackBlack26]

You have to prop down because more RPM+large load caused by big prop=:flashfire: Imagine trying to climb a hill on a 12 speed bike with the tallest gear. Not gonna happen!

Typically, bigger prop = more load = more amps = more heat. So, you prop down and check the temps to make sure you don't harm the motor or blow the esc.

The Prather 220 is 43.7mm vs 42mm for the x642, and the pitch is essentially the same 2.6 vs 2.64.

5S on that motor will produce 40+K rpm, which is SAW range. Can it be done, yes but again watch temps and amp draw since you are beyond the "normal" suggested range of operation. In other words it shouldn't be a surprise if you blow something. :Sinking:

[bbosncali]

Makes sense... but how do you what's too big of a prop? You suggested a 38mm to 40mm with 6s so what would work with 5s and again how do you determine that other than trial and error?

[Brushless55]

was your run with the X642 on 4s?

[bbosncali]

If kv is mutiplied by vlts and the manufacture rates there motor to handle 23 vlts which would be equal to 50600 rpms then I should be well under peak load at 18.5 x 2200kv = 40700. Wires are 10 gage from the esc not sure about the motor 5.5mm connectors ec5 on the batter with 8mm wires from battery. If its gonna go atleast I prepped it right..... I think

[pyroM!KE]

I run a m445 and a cf45 on 5s with out any probs..Of course Im using a SK180 esc..Temps are in the 105-110 range..Ohh this is with the stock motor too..

I'm sure this motor can take 60,000rpms
but if its over propped, things will smoke
the wires will be plenty big enough and good connectors to

[bbosncali]

With stock motor that's only 1500kv its a lot less rpms that's only 27750 rpms as aposed to 40700 which is where it goes into that gray area so I'm learning. And 22.2 is at 48000+ is really pushing it from what I'm understanding

yes that's a lot of rpms for boats

[bbosncali]

New motor mount and 4082 leopard

[bbosncali]

And a set of auto bailers

http://i1094.photobucket.com/albums/i446/bbosncali78/2011-04-30182239.jpg

[bbosncali]

Hit a personal best with a 4074 2000kv tacon motor on 6s and a x642 prop

http://i1094.photobucket.com/albums/i446/bbosncali78/2011-05-07132951.jpg

[Shaun78]

Not bad, but look the genesis hit 63.7mph..........http://i1208.photobucket.com/albums/cc373/SAshton78/2011-05-07140656.jpg

[bbosncali]

Lol on almost your last run of the day.... I had you all day and you beat me out by .3mph lol

[Brushless55]

how many runs did you guys do to back up these speeds?
Lots of Mojo there! :rockon2:

[bbosncali]

how many runs did you guys do to back up these speeds?
Lots of Mojo there! :rockon2:

We ran for an hour or 2 making adjustments and playing around 2 sets of batteries I hit right after that run 60.1mph 60.6mph and 60.5mph must have hit a good gust of wind but still my best of the day with consistant 60's with a $60 motor. Still have my cc1518 and 4082 2200kv to try to try and break my best. He was hitting consistant 59's all day in his genesis and on his 2nd to last run hit that 63.7mph good day for both of us

[Brushless55]

I may need to try my Medusa 3670 2300kv in my Mean Machine on 5s now! :Peace_Sign:

[bbosncali]

Well I was definetly pushing that motor on 6s but had good temps never hotter than 105 on either esc or motor 119 at my ec5's but I was only getting a little over 3 mins of play time but a lot of fun watching that thing go

[TheShaughnessy]

Little adjustments really do make a big difference, put my strut up a 1/16 of in inch from where it was and i gained some visual speed, This was also using 4s1p instead of the 4s2p set up i usually run. Felt like i was easily getting to 45, maybe more, could be talking out my ass with no gps though, got an app for my phone that may work well enough. Next purchase may be an eagle tree with the gps sensor.

Yes they do. My buddy told me to angle my strut up a bit I did that moved my packs back 2 inches and went from 49.5mph to 63.4mph on the next run with same prop just a slight adjustment. Could only pull solid low 60's after that run but still very happy even with that. The eagle tree is nice cause it can do everything but for the money I love my garmin forerunner.

[Brushless55]

yeah moving the packs back will loosen up the hull and make it run faster
I run my MM at 8" from the transom

[TheShaughnessy]

solid 60's are nice, but i do like having a little bit of run time.

[bbosncali]

Well now I've got good run times with 60mph passes with my cc1518 so far a best of 62.1mph with that motor. Definetly happy with this setup although I lost my my flex shaft that day so I was getting some slip can't wait to see what she does when I get my wire drive

[ron1950]

60 mph just says to me that its gonna break as soon as it flipps over.....good luck with it....ill stick with 4s lol......

[bbosncali]

Yeah I've been pretty lucky it hasn't flipped yet its come up once or twice a little chine walk hear and there but I can live with that. I seen what jpriamis looked like after his flip so I'm crossing my fingers

[TheShaughnessy]

60 mph just says to me that its gonna break as soon as it flipps over.....good luck with it....ill stick with 4s lol......

I just split the front of my hull the other day on 4s. Was running in some super chop when i got a little balls. Nose dropped off a wake and submarined hard, broke that batts loose and they flew in the front of the sponsons. I think i hit the lake bottom and that is what split it. Lots of flotation in the front so i know the packs didn't get all the way up there. I just dremeled out the split a bit filled with epoxy and now just needs a little sanding. Should be back in business by tomorrow. 4s 6s, either way it can break but i guess 6s is really asking for it.

[bbosncali]

No pain no gain.. unfortuanetly I already lost 1 boat and didn't even wreck it just hit a wake and it submarined and never came back up so ill keep having my fun at 60 because the boat I lost was on 4s and was only hitting mid to low 40s
