I'm gonna work on that tomorrow. I'm going to tackle one of our engineers and beat some info out of him for you guys! :)

Good to see you here! I talked with out on RCcrawler also I believe

Waterproof?

[Quicksilver]

I've been wanting to ask this for a while now, what happened to the 432m esc. That thing was great, it lasted me a decade......but I dont see anything with specs like that one had. 6-32 cell and some ludicrous amp rating

[domwilson]

I would like to see an Brushless ESC with the following:

1.) High continuous amp rating >150 amps
2.) Waterproofed with water and/or fan cooling.
3.) Easy programming capabilities
4.) 22v or higher voltage rating at 150 amps.
5.) Good customer service and support.
6.) Very competively priced.
7.) Detailed specifications.
8.) Hassle-free warranty.

I hope that's not asking too much.

The 432M was a unique controller with high voltage ratings,
but not as burly as todays components or as efficient. The
higher voltage fets do not tend to switch as well. What
made it work well was the excellent water cooled heatsink in
direct contact with all the fets. Our Fxpro is superior in
all areas with lower resistance, higher current handling,
improved patented fly back circuit and super trick switching
for max efficiency and minimum heat. However a separate BEC
unit is required for use with 4s or more and we cannot get
direct contact with the heatsink on all of the fets due to
the stacked power boards. It is not waterproof, but
probably almost as water resistant as the 432M. We do coat
the boards very well with a protective layer. We probably
need to consider some sealant for better protection.

Fxpro brushed fwd only 416amps.
FxRpro w/rev 208amps.
R1pro or Rspro in brushed forward mode 624amps.
R1pro or Rspro in Brushless mode 208amps per phase.
These are in ideal conditions like temperature. SO if these are properly cooled this is where we'll be. If they get hot we thermal and simply shutdown.

These should get you in the ball park. As you guys know boats aren't on a constant load either.

We are making a 1/8 BL controller that will work well in
boats with extreme setups. It has a built in BEC for up to
6s battery and a heatsink with a fan for cooling. We can
easily make a watercooled heatsink and bag the fan for a
boat unit. The unit is reasonably small at about 2” long
x 1.5” wide x 1.2” to the top of the heatsink. We are
also going to offer 1/8 scale motors like what some of you
are using.

what does the FXR handle in amp ratings and voltage...since I have 2 sitting here....and they are small!

[Eyekandyboats]

if they are so small. how can i take the heat of the
208 amps per phase....
for some reason i dont think it would handle that in real world.
i would like to try one... but when i blow it up i am pretty sure it would not be under warranty.

[00garyc]

dom i completely agree!!!!

[TekinTeamMngr]

I would believe the FXR non pro would take about half of the Pro's amperage which would put it around 208 or so.

We have the most fet's in our R1 Pro and RS pro than almost any 1/10 brushless controller period. There are 48 top level fet's and fet drivers that make the magic happen.

We seriously put a straight short from battery to motor with little to no loss at all. This means top power to your motor(s).

Eyekandyboats what motor(s) do you run in your boat? I can answer the questions better if I know what type of loads to expect.

We have guys running dual 9x2 hand wound modifieds in heavy racing monster trucks for drag racing that are running off of a single FX Pro. Trucks weigh around 8-9 lbs.

[rockwerks]

I have found that size of the esc has absolutely nothing to do with quality or ability to take abuse or amperage. The quality of what goes into the esc is most important.

so the FXR will handle about 104 amps? I tell ya what Im going to put it into a hull this weekend a 8 cell mono with plet motor...Hey is this thing waterproof?

[domwilson]

I looked at your site and it appears that your ESCs are rated to only 3s lipos. Can these handle more? How hard would it be to water cool these? Would the warranty cover mods like this? Alot of FE boaters are going for the Chinese ESC's because of cost, realiabily, specs and word of mouth. Warranty isn't so much an issue because of the lower cost. If ratings/performance are much better, and the warranty is hassle free, then cost would be less of an issue. But that's just my humble opinion.

[TekinTeamMngr]

They're not "water proof." They are water resistant due to a coating that is applied. Our esc's have a smaller footprint due to our stacked powerboards.

We are working on aluminum lower housings for heavy load use and these could be attatched to a standard water cooled heatsink as well. We may be looking at one that has the tubes drilled into them as well if the market shows we need it.

Our support group is top notch. They're easy to reach and have a wealth of knowledge.

Yes the esc's can take more the 3s when a seperate BEC is used. The batter rating at 3s still allows for the onboard BEC to be used.

[domwilson]

How many cells can they handle?

[Ub Hauled]

their 1/8 scale buggies had 4-5s on them...
