Hi captains,

I went ahead and deletedall the pictures that were not cooperating above and reposted them. They seem to work this time..Hopefully it will be better for all to see.

Sorry about the vanishing comentary Dauntlessfan. I had that happen to me a few times so now out of habit I highlight the entire text and copy it before submitting...This has saved me from redo's so many times...

The boat is much faster than in the past. In the short video the low voltage alarms were going off so she wasn't performing at 100% then leaves fouled the props when I turned the boat around...I am happy with her speed and seeing this big girl get up on plane is really cool.

I have to lay up Dauntless for a while. Her sound module is defective and I have to disconnect it and send it back to Canada. The speed controls are currently wired into the module. The defect was that when I turned on the sounds there was a piercing feedback sound coming from the speaker. According to the designer it should not be..

-Rich.

I couldn't get the right two on the top row to open. Is it just me or is there little evidence of Sandy in any of those pictures? My trip to Connecticut didn't show me much more than power outages though, due to my not going down by the coast, that might account for it
Hey Hydro...If you are ever in the area let me know & perhaps we can make arrangements to go sailing..

i think i got it i need a total of four 6-8.4v packs so i get 16.8 volts.2 per esc i was  thinking that the graupner 700 bb turbo 9.6 would not handle the 16.8 but  the specks say it will

Yes sir, that setup will be "plug-n-play" and those 700 bb turbo 9.6 motors should push her along very nicely! Your boat is looking remarkable too, by the way!

More importantly you bettter see if your ESCs will handle that voltage or you are either going to burn them out or they will be shutting down all the time. Most Escs I have encountered will not take more than about 14v including the 208D. Also with that voltage those motors and esc will run hot so you will need water cooling. I have those motors in my Dauntless and run them on 12 v.. You can run with 1-12v NIMH per motor and the larger the mah of the batterythe more run time. If you put 2 12v INPARALLEL per motor you are still running on 12v per motor but you double the running time. If money is an issue i would start with 1 per and add the second later.
Here is a pic of my setup of 2 12v per motor . (total of 4 ) They are stacked 2 high with the 2 on the left for the port motor and the 2 on the right for starboard. To wire them, as I told you before, Y harnesses are available either in series or parallel. Series doubles the voltage while parallel keeps same voltage but doubles run time.I don't thinkI can make it any clearer than that.

If you have seen the videos of my boat you will know it moves well with 1 1/2" props and this 12vsetup. IMHO you are asking for problems if you go 16.8v even with the motors over any amount of time and i think Graupner and Mabucchi would tell you the same.

BTW I went the cheaper route with emergency gel pack batteries first and they would appear to go dead quickly. After sitting a few minutes they would recover for a while and repeat the cycle. Wound up being a waste of money so I replaced them with this setup. If you look on Ebay you can find good deals on 12v nimh batteries. go for the most mah you can for the most run time. Notice mine are 4200 mah. Still cheaper than GOODlipos.

pic of Y adapters One on left isparallel, one onright isseries. Notice on left red to red and black to black On right notce one side loops to other male plug. Plug on bottom (female )goes to ESC the two males at the topto the 2 batteries.

No Deep you won't need to modify any wiring in the situation you described.

Deep,

Don't know why but none of yur pictures will download?  Seems to be a system problem.

All Captains,

FYI, there's a new Dauntless kit available on fleabay at item number 150946814054.  It has 6 days to go, started 9 days ago at  $0.99 and is now only $56.  Running hardware kit is included in the sale, kit 2332.  Just in case you know someone looking for a kit.

Bob

????? He is talking about 4 motor leads when he really means 4 battery leads since "motor leads" would be from the esc to the motor. He said he was going to use 4 batteries, 2 for each motor and each would be in series to get 16.8v. DF, are you saying you think he should be using 16.8 v to his esc and motor? If so we don't agree but have at it and it will be interesting to see how it works out.
Maybe it's me who is missing something here so I'll leave it at that and not comment further.

Hi Bill, the EVX-2 is different from the typical ESC in that it has two battery input harnesses ( + and -) and two motor output harnesses ( + and -). It's advertised heavily by Traxxas as a 16.8 volt ESC since it can accept two 8.4 packs.

I'll post a few wiring diagrams tonight to clarify.

I see, I am not familiar with that esc (really different)but I still would not run those motors on 16.8 since that is probably the max with no load. I find it hard to believe they will last long and besides as we know the boat does not require that much voltage to run with those motors.

Yup I think 12 volts is probably the sweet spot both for the motors and this boat. I'll include that setup in the wiring diagrams.

Hi Dauntlessfan,

So the speed control takes in 16.8V and the output is (2) 8.4V jacks for the two motors?

In a perfect world I still think he would have been better off with the Astroflight ESC's..IMHO.

Close but other way around, it takes in two batteries 6-8.4 volts and the output is double, up to 16.8V max. I'll clear it up by posting some wiring diagrams tonight.

I get it now...one 6V battery input has a 12V output...

What that esc does is put the 2 batteries in series thereby doubling the voltage. That means you get the most votage out of the combo of 2 batteries but less run time. Not my cup o tea.  

I opt for longer run times in my boats so all but one have 2 batteries in parallel.

Yes Deep that is correct and would work fine (your output voltage would be 14.4).

And yes Bill you are correct as well on the series statement as well.

DF are you using this esc? Interesting reading the specs. Notice motor limit and about thermal shutdown. Also about the 0 timing for reverse



Bill


Motor Limit: EVX-2 Marine has a 12-turn 550 modified motor limit whenInsulate the Wires: Always insulate exposed wiring with heat shrink tubingUse Neutrally Timed Motors: For reverse use, the motors must have 0°Motor Capacitors Required: Ceramic capacitors should be properly installedNo Schottky Diodes: External schottky diodes are not compatible with

the motor is properly geared. A water cooling kit (Traxxas part #1580) is

required for modified motor use in marine applications such as the Villain

EX. If the motor or speed control is overheating, try a smaller pinion gear.

Do not attempt to use a more powerful motor (fewer turns) than the above

mentioned motor limits or you could experience frequent thermal shutdown.

to prevent short circuits.

timing. Modified motors (with adjustable end bells) timed to 0° or Johnson/

Mabuchi (closed end bell) motors are recommended. Using motors with

other than 0° timing will draw excess current in reverse, and can result in the

speed control overheating and premature motor wear.

on every motor to prevent radio interference. These are already installed on

the factory Titan Marine motor.

damage the ESC and void the 30-day warranty.

My motors & ESC's are Astroflight and you see I have a no-nonsense setup...

I mentioned this time and time again..go for the Astroflight ESC's..

Here is what I find comical...So many people cut corners to save money and then have to spend even more moneyto do it all over again...I've seen this happen on the forums for years..

Isn't it cheaper to just do it right the first time?
