You can't go wrong with a Wasp. http://www.robotpower.com/products/wasp_info.html I've used these as well. They work well and are cheap. https://hobbyking.com/en_us/hobbyking-x-car-45a-brushed-car-esc.html
A liberty ship weighs considerably more than a destroyer, for it the Hobbyking xcar 45a ESC is perfect at just over $10. It would probably work well in a destroyer as well unless you absolutely cannot spare the weight, only then would I suggest using the wasp which is nearly $40.
Agreed. But for those who want to experiment, a higher voltage capability opens up a much larger selection of interesting brushed motors.
Don't forget the Hobbywings! You don't have to water proof, and the 60amp is nearly half the size of the hobbyking 45amp. Note a 25amp is good for most all ships we use and are upto 3S lipo http://battlersconnection.com/hobbywing-25-amp-brushed/ http://battlersconnection.com/hobbywing-60-amp-brushed/
Charley, How do you all handle speed end-point adjustments with these auto-calibrate ESC's? Do you reset the endpoints after each power cycle?
Nope, install.. adjust speed once done. I never touch again unless I need to speed test and all I do is change endpoints no resets etc...
this is the note from the manual Note：WP-1625-BRUSHED has no optional running mode except the default “Fwd/Br/Rev” mod)
Doesn't this seem like a strange argument to make for an ESC for a cargo ship? Is there a good argument to be made for running 28V in a 34sec target?
It is a strange argument I would agree. I'm sure you could probably find something inexpensive in that range from a surplus store. But not likely cheap enough to offset the cost of the wasp ESC.
If he's new to this, experimenting with high voltage setups is probably not the smoothest intro to RC naval combat For an experienced person, sure. But as a new guy will be generally needing help with his first boat or 2, using more commonly available equipment will mean that more people are familiar with what he's using. I'm certainly not down on new tech and you know this
I know. I just hate to see someone going brushed to get stuck with 6v motors just so they can save $20 on the ESC. Remember, a higher voltage ESC will happily run a 7.4v system and give you the option of upgrading later. If keeping it simple is the goal, IMO the car ESC's do not do that. They all will require changing from fwd/brake/rev mode to fwd/rev mode (car guys call this rock crawler mode). In addition, most of the current crop of car controllers does not support full 100% reverse function. The 25A ESC that Charley pointed to doesn't even support fwd/rev mode so that's an issue.
