Motor/ESC and battery combo - will this work?

[Diesel6401]

Very lol

So I'll go for which ever I can find the cheapest out of the two then.

Thanks for the info on the KV issue. I wanna run as many volts as possible, so 5/6s I guess.
The prop is the one that came on the boat, I was going to get it all up and running and play with prop size after.

Just looked at your vids... made me laugh... I have looked at them before and are one of the reasons I got the UL-1 LOL! Oh well, live and learn.

I wondering if I should give the setup I have a try, it might be fast enough for me. Or is more a question of things will over heat?

Well volts and KV go hand and hand. You can't get a high kv motor and throw a lot of volts to it. Bad things well happen. If you want to run 5s and 6s 1400-1600kv range. 5s for sport and 6s to turn some heads. The CC 1520 motor may suit you, but the 180 esc's even though the are rated for 6s it's not good to push them to that limit often. I would say the 1520 castle motor on 5s would be a nice setup. 45mm-48mm prop range to start. Disconnect the bec on that esc and run a external rx pack. Good habit to get into.

To your question, I think the initial start of the boat trying to get on plane would prob blow the cap on the ul-1 esc. Amps peak on starts. JMHO

Flying: Dubious hull?

Diesel: Looks like I'm gonna be hunting for a new setup then. Oh well, at least I found out now before cooking something.
The 1520 has fins on it, does that mean I cant run a water jacket?

This info is priceless, thanks...

Thought id post a quick vid of my NQD "Spurt" for a possible setup suggestion. Its basically a copy of the Hawaii. Feigao 14XL on 6s with the Turnigy 120a speedo. Still has the steerable outdrive on it with a beefed up u-joint coupler. Runs about 120* with this setup.

Here's a cooling jacket for the 1520 finned.

Make a wave: thanks for that, give me a good idea of what I'll be looking at :)

Diesel = legend

The Castle looks like what I'm after, but might be a bit long for my setup. If it is, do you think the leopard 4074 1774Kv would work well? Its a bit shorter and might fit in more easily.

Sorry for question over load... but when you find someone helpful you tend to unload all you unanswered questions on them lol

Yes that motor should work nicely. Run 4s maybe even 5s. I run a seaking 120 with that motor.

[Simon170]

What size boat is that in, how many cells? Be good to see how it goes for camparison?

Was also looking at the Feigao 580 8 or 9 L.

That's in a 29" skunk cat I run on 4s with 48mm prop got 47mph WOT the whole time. Video to come on that cat. I would use a leopard 4082 1500 over that Feigao. http://www.offshoreelectrics.com/pro...o-4082&cat=148 I ran a 580 in a genesis cat, click the genesis video in my signature.

[Simon170]

Holy smokes! Thats Genesis moves with that setup!

You think the Loepard would be better? I'll go with the Leopards if you think they are better, as you know more than I.

I was thinking the Traxxas Titan setup (1600KV/6s) would be good. I've decided to stretch the budget (here starts the slippery slope lol) So the 1500kv Leopard would be spot on! Is there much difference between tha 4082 and the 4074? Its just that thebulk head sits behind the motor and space is tight, so the extra 8mm might come in to play.
Glad I found all this out before messing about with that UL-1 setup and wondering why its was struggling...

You think the Seaking 180A might be pushed at 6s? Hmmm will have to find another ESC if I go down the 6s route.

I can feel the onset of being poor...

The Leopard motors are far superior to the Feigao motors. If you have a tight fit and the extra 8mm is too much then the 4074 will work for you and may be your best option. Biggest difference between the 74 & 82 is the amount of wattage the motor can put. If you want to run 4s or 5s run the 1774 if you want to run 6s run the 4074 1400kv. On 6s you may want to look into a HV esc or do some research and see if people a successfully running the seaking 180s on 6s. You could try a seaking 80amp HV esc, but you may be pushing the limits of that esc's amp rating. The next reasonably priced HV esc is the swordfish 240HV.


*EDIT, seems people have successfully run 6s on a the seaking 180 esc's, 6s2p seems best*

[Simon170]

Thats good to know, thanks. I think I'll go with the Leopard 4082, I'll just have to pull my lovely handcrafted motor mount and start again. Damn it.
I recently saw cat video on here that had this setup:
34" hull
Leopard 4082 1600kv (even though I can only find it in 1250 and 1500 kv
Turnigy 180A
6S
42mm prop

and it went like a rocket!

From what I've seen on the Leopard website, they draw a maximum of 120A, so I *should* be ok with the Turnigy (although I'm sure theres another factor I dont know about yet)

One last dumb question... 6s2p? 2 lots of 6cells in parrallel...?

4082 is a GREAT choice. You can either use your own mount or get the Leopard mount. Prop size has a HUGE effect on amp draw. The 1500 will serve you well. You are correct on the batts. I run 4s2p in my Pursuit 32" mono on a leopard 4074 2200kv. I have a HD video on my skunkcat with the 4074 1774, but haven't uploaded it yet to youtube. It's a 1080p vid so it's gonna take a long time to upload.

[Simon170]

Right that me off to Hobby King then... LOL

Going to get some 2 x Turnigy Nan-Tech 5000mah 6s 25c-50c packs (unless told otherwise)
Man, 12cells on board is gonna be heavy, but I should imagine the extra run time will be worth it.

I can not begin to thank you enough for your help, I was truely lost at the start of this thread.

[Diesel6401]

Yea 12 cells is going to be a lot especially at 5000k.

Here are some options:

http://hobbycity.com/hobbyking/store/uh_viewItem.asp?idProduct=9341

I run 3600mah cells in parallel for 7200mah. I always run 3-5 minutes regaurdless of the mah count. What happens is after 5m or so of runtime your temps get to high. If everything in your setup is cool after 5 minutes knock yourself out, but it may not be. Also remember run wide open throttle as much as possible as this is less heat and work for the esc, throttle runs less then wide open is hell on the esc.

Thats alot of motor for that ABS hull..................it may not be sturdy enough to handle that power. Mine has all it can handle with the 540XL. You should consider a major reinforcement project on it. Good luck and i'll be following along!!
