12v speed control ?

[thierryc]

What choice is there for 12V electronic speed control ? So far I have only used 6V systems and was very happy with the cheap and resiliant Traxxas XL1, but for my new boat I might go to 12V, and so far the only ESC that I found that can handle 12V is the Super Rooster at $150, knowing that I need 2 of them, the wife is never going to allow that, what else could I use ?

Hi ThierryC

I have chosen to use a Graupner "Navy V40R" as the 12V regulator AND power supply to my receiver as well. (It has BEC) The regulator is watertight, is reversable, wide voltage range, and can handle quite alot.
Please see this link for detailes and tech. data]http://hjem.get2net.dk/robse/SSBN/EngiServ.htm[/url]

and scroll down to "Regulator" I can mail U a picture if you'd like...

Thierry,

I use both the SubTech

Thierry,

I use both the SubTech and the OTW speed controllers with 12 volt batteries. Both work fine. I believe that the ThorDesign ESC is also capable of supporting 12 volts too.

Thanks for the info, the

Thanks for the info, the SubTech and the Thor ESC are only rated 10Amps, isn't this a bit small ? I am used to the 75Amps of the XL-1, and knowing that my boat is big and heavy, I wouldn't want to blow an ESC nor a fuse every 5 mins. How well can they handle power ?

Hi Thierry]http://www.subcommittee.com/forum/icon_smile.gif Typically the 75

Hi Thierry]http://www.subcommittee.com/forum/icon_smile.gif[/img] Typically the 75 amp controllers are used in model cars with brushless motor with specifications like 14-T (14 turns of wire). My Typhoon was modified to operate with a 12 volt battery, that is 12 volt motors, relay mods, etc. The only thing that remained at 6 volts was the receiver.

vantec makes 12 volt speed

vantec makes 12 volt speed controllers for a much more reasonable price.

i have two of these, and they have been working fine for several years]http://www.harbormodels.com/SpeedControls.html[/url]

I am using them in a Dumas Mr. Darby (60lbs), with 30amp 12 volt gel cells running 2 Dumas 12v pittman motors (monster motors that pull about 12 amps continous).

not listed on that web page, but they also make a cheaper version that is rated for 6 volts.

I would recommend them in a heartbeat.

Duh ! I completely forgot

[color=#0000FF]Duh ! I completely forgot that when doubling the voltage the current is divided by 2 to keep the same wattage V X I = W
I guess that's what happens when posting at 11]

I ordered mine from a Danish retailer called

http://www.hobby-world.dk

It's a $88 set-back, but well worth it. The shop deals on-line with credit-cards, just drop him a mail asking for the regulator. He orders from Graupner every 3 weeks, and then sends it out once it's prepaid. He's eMail is hobbyworld@hobby-world.dk and the regulator is called "Graupner Navy V40R, no. 2875" You might wanna try a 'local' Graupner dealer to save some of the shipping?
Hope some of this helps.

Hi Thierry]http://www.mackproductsrc.com/index.htm,[/url] you can get some really great motors. When you look inside a motor at the windings like the motors that came with the Typhoon, notice how the windings are "scramble" wound. If you look at the mack motors, the windings are neatly placed next to each other. When you cross a winding, you negate it's effect. Torque wise, I can not stall the mack motors at any speed with my fingers. If you are converting your Typhoon to 12 volts, let me know. I've already done this. Back to PIC programming 101.

Hi Thiery,

Hi Thiery,

In my opinion, LRP-electronic in Germany produces some of the best ESC´s around. They are mostly into RC-car racing, and for my Patrick Henry running at 6 Volts, I use an F1 Reverse Digital that can handle up to 30 Amps. continuesly.

For 12 Volt users, LRP actually has a specially for boats designed Marine Reverse 12 Volt. It can give up to 35 Amps continously, and has a 5 Volt BEC that can handle up to 4 servos.

Are you planning to convert your Typhoon to 12 Volt?

Thanks for all the information

Thanks for all the information guys ! I am not planning to convert the Typhoon to 12V as I am pretty happy with the way it is running now in 6V but I am building a new boat, japanese B1 class 1-35 and this one will run on 12V
