Leopard 4082 1500KV

**Shaun78** · 04-01-2011, 03:44 PM

Who's Model? Would the spartan be faster on 1450 KV or the new 1600KV coming out? i want a faster max speed so I can run the boat with packs forward and strut level or so in order to get no or limited death wobble and still hit mid 50's or so comfotable. but high 50's to 60 maxed out. That would be ideal i think

well you would need to prop up on the 1450kv and smaller with the 1600kv
so your speeds could actually be the same in the end

Shaun, HiModel is an offshore hobby shop similar to Hobby King.

Just google the name. You need to create an account on their site to get the best prices.

And as Brushless said. The 1600kv motor will run at a higher RPM. So with the same size prop the 1600kv would be a bit faster.

You can go to a larger size prop and get similar speeds out of the 1450kv.

Remember though, that it isn't always about top end speed. For sport boating you want good speed, good handling, and the ability to get quickly back on plane coming out of a tight corner.

It's about finding a good balance.

I agree with BL55, we all see what's Traxxas's recommendations have let too. I read there manual on the spartan and I don't agree with it at all.

Straight from there manual: http://traxxas.com/sites/default/fil...8_manual_0.pdf page 23

Traxxas recommends a motor with a kV rating of 1600-1800
kV

They recommend 1800kv? On 6s (stock can run 6s and they don't tell you not to run when going to a higher kv)? Seriously?!? You recommend people to run a 1800kv on 6s thats around 40k unloaded rpm. That is TERRIBLE advise! They don't recommend a motor size either, so some new guy is gonna go grab a 1800 540xl motor (that's the size of the stock motor so they don't know any different)and run it on 6s and blow his whole system up. This is pretty much a sport boat 1600 on a 6s with a 540xl motor is just not good. 1500 would be more reasonable or lower kv with higher voltage with a 540xl can. JMO of course. I wouldn't listen to Traxxas though. If you want to run 6s a Leopard 4082 1500kv would be a great setup and add a HV esc so you aren't pushing something like a seaking 180 to the limits. A CC ice 240 would be awesome in this hull as well. I would reinforce the hull best you can. If only a matter of time before the plastic hull starts to show wear and tear of running at those higher speeds.

i was going to get the Turnigy,Hobbywing 180amp ESC. I can get the 1450Leopard for a good price thats why i was asking. The T180 ESC will handle this right (1450,1500 or 1600KV whatever I get)

**Shaun78** · 04-01-2011, 08:31 PM

thats my other issue, i wanted to keep stock. I dont want to spend all my time replacing hulls,flex shafts etc because i am running too much power. I would be happy with 50 or low 50's with great reliability. (i am going to try a P220 on stock setup,see if i can reach 50 that way)

Make it short if using the stock motor, that prather prop has a good bit of pitch and on a less then effecient 2 pole motor things are gonna heat up QUICK! If you are a sport boater (just for fun, not racing) don't let speed chasing get the best of you.. Just my 2 cents.....

The esc will handle the motor, I don't like pushing esc's to there max voltage (personel thing). Some people have ran 6s on those esc's without ever having a problem. Others have blown on plug in, where I stand is I will never find out which is what because I don't ever plan on trying it. That's just me...

what is your choice of esc for these bigger thumpers?

**Shaun78** · 04-01-2011, 08:42 PM

u r saying the T180 esc is maxed out on 6S with those motors? it seems thats what everyone is using with upgraded motors and I havent heard on any ESC's blowing up unless its the stock traxxas one. OR were u referring to the stock setup? I could also try an X642 prop on stock setup. This boating thing is making me crazy...maybe traxxas will come out with a better motor esc combo on version 2 and hook us all up that have generation 1????? wishful thinking on my part

5s a seaking 180
6s a HV esc, Ice 240 or a swordfish 240. I have/will be running a Ice 240 with my CC1717 on 6s2p. Also I think 2p setups would be a must for the bigger motors.

Yes (VOLTAGE WISE). The amps is not why I suggested moving to a different esc. The voltage is why I suggested that. The esc is rated at a max of 6s. I don't run any of my esc's at there max voltage. I have seaking 120s, 180s and I never run them past 5s. I also have/had swordfish 120s and 200s and same thing I never run them past 5s.

I run a T180 with a Leopard 4074 also ran it with a Feigao 580 never had a issue. I even pulled A CRAP load of amps in that esc without ever having a issue, but I never pushed it past 5s.... Esc is pretty old and still ticking hard!

**Shaun78** · 04-02-2011, 06:24 AM

The Castle HV and ICE. Those things are like 300 and up. I dont have it in me to spend that kind of dough on a speed control to go 10mph faster. just me though

That was my mind set as well, I looked at better ESC's, but wasn't prepared to spring that kind of bucks on one.

Diesel's philosophy is sound, for any type of equipment, if you don't run it maxed out it is easier on the equipment.

But I'm going to do as others already have, run a T180, 4 pole motor, and 6S.

One would hope these ESC's have been designed with a bit of safety factor built in so they will operate reliably at the claimed specs.

uhm can you say traxxass

the T180, many are having great runs on 6s with no issues at all..
D just plays things on the more safe side.. I'm acutally thinking of running my PT Hydro on 5s now with this T180 esc on a CC1717 and using a bigger prop to get the same speeds I wanted on 6s
