But I dunno gasoline would be nice too, get more running time. But then I don't know much about them.

I think a kb 45 xl motor on 10-12s 2p would be good.

Turnigy have a HV watercooled boat esc on hobby city : http://www.hobbycity.com/hobbycity/s...hless_Boat_ESC

Pair that with this motor : http://www.hobbycity.com/hobbycity/s...hless_Inrunner

And run a pair of these lipos in series : http://www.hobbycity.com/hobbycity/s...idProduct=7300

That combo should be good for 4+ hp... Not sure how fast it would get that boat going, maybe 35-40mph.

[nitrostarter]

Yeah, anyhting over 40mph, you'll need Neu or Lehner power on 10s2p minimum. Or a nice gas motor.

Stock Zenoah 26cc with a 257carb will push that hull 50-53mph with a nice prop. And you can get this Zen on ebay for $205 shipped.

I think I will need your help when I setup the big gas boat...

I was thinking about using a feigao 540 14xl I have in a 29" boat hull I have laying around. Get that turnigy boat esc I linked to and use 8s lipo... Not sure what hardware to use on this boat. Was going to get some SV27 parts, but I think there may be better stuff available. Want to do it cheap, so I may try to scare up some used hardware. Time to hit up the swap shop on OSE!

That would be nice budget setup. These boats suck lotsa of current, what kind of running times would that setup give? I would gues something 10 to 15 mins with heavy finger.

But I have now so many things to do have to finish my 2 Genesis trucks, change v3 diffs to my g2r and last converting my new Team Magic buggy to brushless. So really dunno when I have the time to build it. But definitelly will ask help for you guys when it's the time for it

[nitrostarter]

10-15 minutes is a hope and a prayer away. Electric boats are good for 3-8 minutes depending on setups. Which is why I suggested to go with the Zenoah 260 with a 257 carb. runtime plus gas it up and go again...

Sending it back seems the only way to go, otherwise I may have to take it apart to reform a good 3S pack.
Thanks Linc

thought I'd post what a zippy looks like







I taped the cells togeter. It actually seemed like they had some kind of tape or glue in between the cells as I tried to pull two apart and I couldn't. I taped them and then shrunk it black.

The shrinkwrapping actually turned out good this time because I have aquired a hair dryer! It "Fell apart when [she] picked it up". The handle is gone and the switches are bare, but it's hot enough and better then a lighter!

Solder job on the flightmax packs is not as user friendly as the zippy H packs...

[rawfuls]

Wow, look at the solder joint with the positive red wire...
Weak, hope you fixed that before you reshrunk it?

Linc, do you have anymore hard cases you can toss some Zippy's in?

I do not have any hardcases...

I find the zippy lipos do not have much of the main leads stripped and tinned, I usually like to have at least 3/8 of an inch of tinned wire to make contact on the solder pad.

[rawfuls]

Alright, what would you use, for protecting your lipos, besides just a battery tray....

My lipos always get scratched up, and I'm just generally scared.

Also, anyone have any experience with the high amp lipos with the hobbycity deans?

[brushlessboy16]

The hobby city deans connectors are trash... get rid of them... I have scrapped all mine for use in charging harnesses.

[rawfuls]

Go figures.

Mike told me to just switch all my lipos, and leave the NiMH's current.

I only have 6cells, that's it.

And lipos, I have a GT ESC from HPI and the KD 700Non-HO and a TrueRC 2 Cell 5000mAh, and nothing melted... yet.

So, just to compensate, I'm just going to switch all my lipos, and my esc plugs to the real deans, and leave everything else the way it is.

Good idea? Or just plain stupid?

Good connectors are a must. I have seen the pseudo deans crap out... Real deans do perform better.
