CC 1480-1800kv vs Leopard 4082 1800kv

[GTRhino24]

Just ordered what seems to be a direct replacement for the Spartan motor from OSE. It says that they are custom wound for OSE, but doesn't specify whether it's D or Y wind. I'm curious because since I'm running the Seaking 180 at 15* advance, I want to know if I need to change that setting when using the new motor. Anybody tried this setup before? I know some have dropped the kv to 1600-1700, but I went with what was available and believe I can make it work.

Also, efficiency/quality wise, where does the Leopard stand against the CC Spartan motor. I know CC makes good stuff, but is this a possible rebrand?

I assume you bought a Leopard since you didnt say. When I asked Steve about timing with a motor I recently bought, he said to start at 7.5 degrees. The type of wind is unknown, so start with low timing. You should prob even start lower around 3 degrees just to be safe. Run the boat, check temps very often. If all is good, move up to the next timing increase. I wouldnt surpass 11 degrees if all goes well.

[GTRhino24]

Yes, just realized I didn't specify. It's the Leopard 4082 1800kv.

Not much of a direct replacement unless you are taking fitment. The 4082 is a bigger and longer can with quite a bit more power than the stock spartan motor. You will also need to get a larger cooling jacket to fit the new motor. Stock Spartan I believe is a 1600kv and you are going 1800kv. This will be rather high rpms on 6s so do not go there unless you feel lucky. As for efficiency the Spartan is only a 2 pole whereas the leopard is a 4 pole making it more efficient by design. Nice motor combo for the Spart and should scream on 4S with the right prop.

Got the free Leopard cooling jacket (Long) so we should be good in that dept. So you're saying that with the Seaking 180a, Leopard 4082-1800kv, Octura x442 b/s, and 6s2p 40c Zippys that we could go nuclear? I'm pretty sure that the current motor is 1800kv after the Castle Creations upgrades. That's why I was considering this a drop in swap for a more efficient motor.

[Snowride]

Just doing the math, 22.2 x 1800 = 39,960 rpm. A little hot for a Spartan if you ask me. You would be much better running that on 4S IMHO. Not sure what they did to the upgraded motor and as far as I know they added some caps to the esc which seemed to have solved most issues however the motor I do believe was unchanged except for the castle stamp. (both esc were castle even first run however not labeled so) Don't quote me on this as I do not know for sure however this is what I have read time and time again.

Personally I will be testing a 4082 in the Spart come spring however I am using the HK Turnigy version and 1600kv which is about as high as I want to go on 6S.

[GTRhino24]

Uh oh. Oh well, it should be fun for as long as it lasts anyways. I'll back the timing down and work up while checking temps. I still think I can get 60mph out of this thing reliably somehow. If not, I'm going to build a fightercat that will.

[Snowride]

Run it 4s with a larger prop and I bet you will see 60 reliably. Nothing wrong with what you got except maybe a little too much kv to run on 6S. Then again like most Spartan owners like myself, you probably invested in a few sets of 3s batts and want use those right?

I got the 4082 1800 too but haven't been able to try it. I also have seaking 180. Steven couldn't tell me the wind but suggested 7.5 to start

[dana]

I will be running 5s2p btw

Yeah, I've got a 4s, 5s, and 2x6s setups. I got 47mph on 5s and 57 on 6s on the stock components. Stock ESC gave up. Seaking is getting 53mph consistantly on 6s. I just thought a little more efficiency would get me to that magic number. I'm beefing the driveline before the motor swap with a Wohlt .150, Octura liner, and Octura coupler. I'll start at 7.5 and post some results.

It depends on which Spartan he has, first generation was 1600kv, Second Generation, which I think he has because he references the CC motor, is 1800kv.

I ran a 3674 1700 kv Turnigy 180 setup with no issues at all, but tried a Leopard 3674 2000kv and burned up the ESC after 2-3 runs.

The 4082 1800kv kind of slots in between, so you might run without problems on 6S, but in my opinion you are starting to tip the scales toward higher risk of melt down.

I tried running a CC1515 2200kv motor with the Turnigy 180 on 5S toward the end of the season last year and so far (touch wood) it has been reliable.

My daughters Spartan has been running the Leopard 4082 1600kv / T180 for some time now, and it has proved to be very solid on 6S.

PS checked the Leopard website and the 4082 1800kv is not listed, so as Steven said it is a custom wind, with no info available on Leopards site.

[Snowride]

If 1800kv is in fact the case on the newer ones, no wonder that are still having issues!! Like I mentioned before, just doing the math comes to a hair under 40,000 rpm. Not recommended from everything I have seen so far except for SAW. IMHO that is just plain dumb in a RTR beginners boat. If they changed anything they should have dropped it a couple hundred KV as opposed to increasing it. What were they thinking? Wait a minute, just figured it out. They needed to make the boat do 50mph as advertised to avoid a possible law suit. Does not mean it needs to last very long though.

What prop are you using on this and what speeds are you getting with this setup? How long do you think a set of 6000mah 3s Nano's will run? I will not be using the Leopard but I have to assume the HK version is pretty much the same. http://www.hobbyking.com/hobbyking/s...FInrunner.html

FYI, The little project I have going with the Spartan tray is going to be great. A little busy right now to take care of it but my proto-type seems to work perfect for fitment. May consider making a few dozen and selling them to those interested. You sir helped me out with soo much valuable info when I first got my Spartan, I will send one to you for free. Cheers.

Yup Not sure what they were thinking.

We experimented with a variety of props but pretty much settled in with the Prather 215. Speeds are consistently in the mid to high 40's on Eagle Tree GPS. We found, as many others have that running the Spartan much faster it gets unstable anyway, so she kind of gave up on maximum speed and settled for maximum fun. Also we run on a fairly big lake and water conditions are seldom perfect, so top speed isn't often attainable anyway.

I still experiment with mine, different motors, different props etc. but I'm a glutton for punishment.

Looking forward to seeing what you are up to with the tray mods.

That is a tiny prop for such a powerhouse motor, no wonder it is rock solid. Kinda like running in first gear all the time. You will need to install a heater on the components to keep things from freezing up? I really think that it would be as reliable with a larger prop and upper 50,s easily attainable. I will not be shooting for top speed either, rather monitor temps all around and let the temps determine how fast it will go. Would like to keep things sub 120 all around.
