Wanna make Miss Geigo FAST...need some input

[gibbies_03]

Hey guys,
I'm new to the forum and just getting back into the boat schene. Had some gassers in the past, but wanna keep with electric this time around...My Miss Geico is gonna be here on Wednesday and I wanna make a few upgrades...So far I have ordered the Octura x642, and the rudder re-location and break-away screws...

Looking at motor and ESC's...found the Turnigy 180 which seems to be pretty popular and very well priced

I'm a little lost on what motor to get tho...I am looking at the 3660SL 3060KV motor...what do you guys think? I am very experienced with RC and just wanna do things the best way possible, the first time around...I know there are better products but I dont wanna spend the cash yet...

Is the 180A ESC gonna help the speed on the stock 1500kv motor?

Any input is welcome

thanks

[gibbies_03]

I plan on running 2 3S 3000 40C packs

[Jeff Wohlt]

Stay with 4S and the 3060 would be waaay too much. Go for something like a leopard 2000 KV or the 2200 KV and a x442 or X642. Should put you up there to the max of the hull. The 180 is great for the above set up.

how fast do you want to go? The leopard 2000kv would probably have you running in the high 40s/ low 50 and the 2200 would be slightly faster with slightly less run time.

There is room for 8s in the MG how much money/ how fast do you want to go/spend?

[gibbies_03]

so ur saying I should stay with 2 2S packs??? or will a 2000kv motor with the 180 do great with 2 3S? thanks

and can I expect any gain from just adding the 180 and leaving the stock motor

I am going to build this boat with a pretty strict budget, and if I really get into the hobby again I will do a custom build and go ALL OUT...Is the Leopard only rated for 4S total? or can it run on 6S(2 3S)

[Flying Scotsman]

Stay with 4S power on that ESC, you might get away with 5S and a low KW motor. The prop will decide your fate

[gibbies_03]

so what leopard motor do I want...I know I want the 2000kv or 2200 but there are several different models...which will fit in the Miss Geico

changing the esc will not yield any additional speed. You could run 6s on the stock motor with the t 180 though.


Depends on what leopard you get. I wouldn't do more the 4s with the 2300 kv but the 1600 kv is a different story.

So i just read you want to run 2 3s packs to make 6s? Get that esc and run the stock motor till she goes, then pick up the leopard. As for prop, id start small, like an x437/3. Not familiar with 6s set ups.

[martin]

1500kv = 33300rpm if you want to run 6s, 2200kv =32560rpm for 4s. Going above & your pushing your luck unless your looking at just short sraight line bursts. Martin.

[martin]

Leopard 4074 2000kv or 4074 2200kv.

[yurkanip]

you could do the 4082 1600 on 6s as well. Using the T-180 esc.

[martin]

Personally i think the MG is a bit small for a 4082 on 6s, But it will be fast. Martin.

[siberianhusky]

One thing you guys missed is the 2 3s 3000mah packs. sure thats 6s but only 3000mah, not enough capacity for what is being suggested. 5000 mah packs minumum.
Won't get much runtime with those motors on that limited capacity before you hit the LVC.
Series you don't add the capacities together just the voltages!

[martin]

Stick with the 4074 2200kv on 4s, Only mentioned 6s because it was raised in thread. Martin.

[Flying Scotsman]

Another thing you should think off, is that the boat you are running is an RTR hull and designed for a specific speed threshould.

Douggie

[TheShaughnessy]

Stick with the 4074 2200kv on 4s, Only mentioned 6s because it was raised in thread. Martin.

the OP said he wanted to use 6s, that is why i said something about 6s.

I think you will be happy with the 4074 2000 kv on 4s. I have a ul1 2030 kv with an m445 and wouldn't want to go much faster. I would think the leopard would be a more powerful and efficient motor then mine, so you could prop up i'd imagine.

I didn't catch the 3000 mah batts. You will be getting 2 min of run time give or take.

With those batts i'd stay with the stock motor on 6 s with the t 180. 1500 x 22.2 = 33300. With an x437/3 or a x440/3 you will be flyin. As i said before i dont know squat about 6s set ups though so i could be way off on prop size, those should be relatively conservative though.


I think the 4082 might be a little much for MG as well. I have a 3656 size can and she is a hand full on that.

[gibbies_03]

you guys are awesome and this info has helped a ton...off to work and then home to order motor...gonna go with the 2200kv on 5000mah 4S...

[bbosncali]

you guys are awesome and this info has helped a ton...off to work and then home to order motor...gonna go with the 2200kv on 5000mah 4S...

I have this motor in my mg with a 150a esc and only running a x642 offset rudder and on 2s 40c 5000mah lipos and it keeps up if not a tad faster than my buddies 6s spartan. I am gonna push the limit though and try it on 5s against everyones advice. I did however buy a backup seaking 180a esc for if and when my esc goes. If you don't want to throw away your money definetly stick to 4s or buy a lower kv motor like a 1500kv or at most the 1774kv jmo

:rockon2:

[TheBoatbojo]

Would the 3660SL 3060KV motor be a good option if it were run on 2s or 3s? Also, what is the main difference in using a low Kv motor on 4s comp with a high Kv motor in 2s?

[jac4412]

High kv=more speed, less "pushing" power. You should really stay away from kv that high in this boat... It's going to be working very hard to get speed. I'd say its a 4s minimum boat.

[bbosncali]

so ur saying I should stay with 2 2S packs??? or will a 2000kv motor with the 180 do great with 2 3S? thanks

and can I expect any gain from just adding the 180 and leaving the stock motor

I ran a tacon 4074 2000kv on 6s with an octura x642 and it screamed hit my highest speed of 63.4mph but my run times were about 3mins with a set of gens ace 5300mah 30c temps were only105 it was fun but not long enough run times. The leopard 2000kv is rated at 25vlts so 5s shouldn't be a problem but that's jmo. I love high rpms but that's also living on the dangerous side and pretty muc asking for something to break. But atleast ill have fun doing it

[cmexeqtu2]

I got a dumb question, but I noticed the lepord motors don't have cooling jackets, Do they need them? or do I just use the stock MG cooling jacket off the stock motor?
Thanks

[ericwpg]

Lepard moters have matching cooling cans sold seprately and my 4082 runs cold so they are worth every penny

[ron1950]

aquacraft ul-1 motors do very well also and cheep

[benjijames]

I also want to modify the boat set up to get more speed but don't want to spend too much money. I want to buy the seaking 180A esc and a leopard motor 4074 2150 kv or 2200 kv. Will it be possible to run 5S with that setup ? Can I keep the stock motor mount or do I need to buy a new one ? What are the matching cooling cans for leopard motor ? Thanks for your help.

No don't run 5s on either of those motors. Stick to 4s with them.

[ron1950]

if u are tight on cash use the t 180 and the stock motor on 4s .....prop it with a m445......5.5 bullet conectors all around and u will get into the low to mid 40's......u will have to dremal the cornor of the strut bracket but thats about 5 min work.......

[ericwpg]

A miss Geico with a 4082 a t180 using the internal bec 6s 5000ma 40c and the pro boat radio with a 42 x 55 Grim Racer prop has pulled 50 runs or so with no problems other than blowing the blades off the original props,and eating a strut and flex shaft. To get rid of the bounce i cut the original strut slot a little lower with a dremel and raised the prop. I also glued a big flat catfish weight to the nose and put some fiberglass to make the front wing stiffer. The Boat is a bullet just stop pulling the trigger 20 feet from shore or your gonna make a hole in whatever you hit.

Nice.... Those leopards do run good but I love my cc 1518 I run it on 6s without any problems I'm over the 33000 rpm mark but just under 40000 and run consistent 60's I know I'd be safer running 5s but when compared to 1600kv motors on 6s it's really not a whole lot more. I'll keep rolling the dice for now

[benjijames]

I have finally ordered a turnigy marine 120 A and a aquacraft ul-1 motor 2030 kv that I plan to use on 4S. I already have an octura X642 prop. Is this prop appropriate? What timing do I have to put on the esc ? Can I use the water cooling jacket of the stock motor on the ul-1 ? (both motors have 36mm diameters). Can I keep the stock 3.5 mm connectors of the motor or do I have to switch to 5.5mm. Do I have to add a battery receiver pack or can I use internal BEC ? Can I try riding 5S with this setup ?
I was riding all stock on 5S with a X642 prop but I was a little disappointed by the speed. Thank you for your help.

[gek1946]

I need your help. I have a Mystic 29 using 7.4 5500mah/35c 2s traxaas batterys hooked in series.
Ive changed to motor to a 4074 with 180a esc. the prop is octura 645. After changing the motors and esc the boat goes much slower. I have the hobby king program card for the esc and have changed it many ways, nothing has helped. With the boat on the workbench and prop shaft removed the motor has the same rpm no matter how i change to specs on the porgram card. I have used lvc no protection,also 3.2,3.4. Im beginning to believe i have a bad esc or motor. Im ready to change the motor and esc back to the stock. When stock the boat was running 38-4o mph on gps,with the 4074 and 180esc 30 mph is tops, no matter how i program it.
thank you

If you wired the batteries in series then that's your problem your only getting 7.4vlt instead of 14.4 you need to run in parrallel and also make sure your prop is balanced. That's a little big for a 4074. Is it a leopard or an off brand? Also what kind of connectors r u using for battery and motor? I run a castle 1518 in mine with an m645 and hit consistant 60's on 6s.. also is your prop an m645 or an x645? Big difference. If you continue to use that prop watch your temps and add some capacitors. This has just been my experience

[bbosncali]

Ben the prop is fine use an external bec with battery pack for anything over 4s also junk those 3.5 bullets go with 5.5 or 6s also don't use deans plugs the amp rating is to low I like the Ec5 connectors there rated at 120amps hope this helps

[jac4412]

Youre also going to want to make sure the prop and strut height are sharpened and balanced as well as at the proper height (respectively). Raising and lowering the prop by just a couple mm can drastically increase (or decrease performance).

I thank yo for your comeback on my problem. Ive changed everything over to 5.5 plugs and gotten rid of the deans.The motor is a Leopard 4074 and the prop is an X645 octura. I still have the stock stainless prop that came with the boat but havent installed it. The boat was runing fine with the stock set up but i just wanted to faster than slower. Also your information on series and parallell is incorrect, im running on 14.4 volts in series, red to black etc. to creat the 14.4 volts. Thanks again and any other information you have would be appreciated. Does this Diesel who is listed in a lot of these forums is a person who might have some ideas?

Diesel i have a problem with using a leopard 4074/a80a esc. Im listed under Motor ESC Changeover
Ive written to anohter member of the forum and am writing to you also if you have any ideas of my trouble
your help is appreciated. if you dont find me in the forum I can be reached at garykerksick@yahoo.com for some help

thank you

[bbosncali]

I would de-tongue your prop cause that's a lot of prop for a 4s setup. I use an m645 which is already been de-tongued its less prop but it will spin faster. Also what is the kv of your motor? That could also have a lot to do with it. Just my opinion

Sounds like your esc may not be recognizing full throttle. Did you calibrate the throttle? That m645 is a lot of prop, a 2p setup would be much better then a 1p setup with that prop. I would suggest dropping to a m445. What timing do you have your esc set at? Do you have a gap between the drive dog and strut?


What's the specs on your lipos? If you mentioned that info b4 sorry asking again.

[gek1946]

You were exactly right I calibrated the throttle so it would recognize full throttle I hit the throttle the first time and the boat leaped out of the water and ran extremely fast and straight. Im using just a simple lipo 5500mah/35c 2s Traxxas Rustler batterys. I didint change an prop yet. Your advice paid off. The question still is should I get different batterys,and maybe go to a different prop,or should i put back on the stainless that came with the boat? Thanks for helping me out,you know your stuff!

Lucky guess on the throttle calibration ;)

How has the prop been "reworked" ? More then just a s&b? A x645 is a lot of prop, a m445 and a 4s2p is a nice setup or a grim 42x55 or x442 on the batts u have or on 2p would be nice also.

The stock prop is similar to a prather 215. If u s&b it it's not a bad prop.

[Boat guy]

When you say a grim racer 42x55 prop do you mean 2 blade or 3 blade. Any way to run 8s if so what esc can you get. Most I look at only go to 200 and w 8s it will need more. Thx
