ESC Suggestions ????
 

I would like some advice on selecting a better ESC for my SV 27.... I don't like having to arm the ESC every time I run the boat... A switch would be helpful, I am running LIPO's so built in low voltage circuitry would be a big plus.... Water proof case would be a plus, even though I've never had water in the radio box... Fitting the water cooling jacket seems to be a good idea as well. Running BEC needs to be included. What are your thoughts, anyone ? I've experence with running Novak, LRP, and Mamba Brushless in racing Oval and On Road but I'm a new comer to the boat thing.. Are there Aircraft ESC's that might fit the bill as well??? I know that I need at least 45 amps as well as at least 18 volts.. Your thoughts are appreciated! KNOT NUTS (Ole #5)

every BL esc has to arm before you run the boat. it takes 2 seconds and thats all.

Thanks, The ones that I'm most familiar with can be programmed and do ont have to be reprogrammed every time that you turn them on...Simply turning on the switch and go race with the settings exactly as they were when you turned it off. No need to go to full throttle then neutral... I suppose that you meant that arming meant giving power to the ESC??? Are there any Esc's that you can program LIPO low voltage circuitry on and off like you would do with Novak or LRP???

the hydra esc from castle creations is programable for lipos

you need to read your manual for the boat and speedo and you will fix the problem.

No where in my manual is LIPO low voltage circuitry mentioned... It is NO problem to pull a trigger and go back to neutral..... I'm looking for a better animal that's all. I'm sure that there are other ESC's used in electric racing other than the one offered by Aquacraft..... Are all boat friendly ESC's Programmed the same??? I doubt it.

RE: ESC Suggestions ????
 

pretty much. you have to program most every esc you get

RE: ESC Suggestions ????
 

you can just buy a LVC (low voltage cutoff) and still use the stock esc....

and here is the hydra big thunder suggested

Yes I'm aware and am using a Novak LIPO low voltage circuit now.. I'd really like to know a little more about ESC's that are available.. The one (FUTUBA?) that is offered by Aquacraft is more like an on/off switch than I like.... This may be due to the Brushless motor magnets close proximity to the windings. In many Brushless motors they free wheel to a degree unlike the motor used in the Aquacraft.. ie. Novak's that I'm used to racing Oval with. You couldn't use this (cogging) in a race car because it would instantly spin when you let off the throttle!!LOL!! I've looked at the Castle Creations Hydra's and I'm sure that they are a little more sophisticated than RTR supplied ones... A little more pricey too!!LOL But like in any other type of R/C hardware...You get what you pay for!!!LOL Are there any others out there that I could consider???

i just have a question i just got some lipos for the sv27, does the sv27 already have the low voltage set up ??? for 14.8v

RE: ESC Suggestions ????
 

NO!!! You must use an aftermarket device such as a Novak 2s Lipo low voltage circuit!! Without it you'll stand a chance of over discharging your LIPO's and ruining them..

where do i get one tower hobbies>>?? and how many do i need?? and what prop is better for the sv27 x642 or x645??

RE: ESC Suggestions ????
 

Should i get the 4s novak cutoff or the 2s??? and how the heck do i connect it??

RE: ESC Suggestions ????
 

so you re joined eh.

and you need the 4S cut off

RE: ESC Suggestions ????
 

yes tayler i join lol is that easy to set up on the sv27??

RE: ESC Suggestions ????
 

spelled with a "O"

RE: ESC Suggestions ????
 

Tower does carry them.. you'll need only one.. about $25.00...Prop selection has a lot of variables, Trial and error is about the best I can suggest.. Water condition, power, motor, acceleration desired? Top end? I guess it's up to what you're looking for! LOL

RE: ESC Suggestions ????
 

Icccc So its easy to set up the low voltage cut off for the sv27 right?? sorry taylor!!

RE: ESC Suggestions ????
 

Thanks Saleen! their price is a LOT better than Tower!!!LOL!! Have you used the Castle product??? Is it more Linear than the supplied Aquacraft?? My bad Supervkilla, you will need a 4s NOT the 2s.

Set up is no problem... follow the directions that come with the Novak. I used bullet connectors and a short wire and soldered them to the deans connectors that come with the boat. I mounted the unit to the top inside of the radio box with velcro.. Plug the unit into the receiver where the ESC plugs in and the Esc plug to the receptical on the unit itself, per the instructions... You'll need a small hole in the lid of the radio box to exit the two leads that go to the battery harnesses. Make sure to solder one lead to the Black wire and one to the red wire for your batteries.
