Water proofing and basic lines

[Speedfreek]

what is the XL X rated at compared to say... the Edge 200 (which is technically 240a for water cooled) ?

400 max
I am new to electric boats but I have ran my XLX in my cars for a while at 380 ish Amps multiple times.

I ended up using the motors and escs, they worked great on 6s. For the 1ms I gave full throttle the data read 11hp and pulled 325a, on the back of my mind I was a bit worried if it would be completely waterproof and if the cooling would work.. I couldn’t run it that day as good as I wanted since there were sailboats in the lake.

I did not change the caps since I didn’t run twin 8s, but I did add ripple killer cap packs.

Nice, what kv are the motors ?
Going to add 10x10mm aluminium rail like another member here on each side by milling out the cooling fin on top and do the silicone conform 3x on the boards these XLX take the amps easily use it on my rc car speed rig pulling 300 + amps no worries

No way, $1-2 bucks at the most especially if you buy a few or more, it can get a lot cheaper based on the quantity

On eBay it is $10 each

Why not use 470uf 35v rubycon ZL series or similar Chemi-con caps?

I was looking at them last night $10 each

Speedfreek, I build my cap banks using the following capacitor: The following part number is for a 63VDC, 2200uF cap on Mouser: 661-EGPD630E222MM35H

Wow, there very expensive and out of stock.
What did it bring your ripple down to , minimum value max value ?
Thanks

I would love the link to the caps please

So I am in the middle of setting up two Castle XLX esc for their voyage in my zelos along with two TP Power motors. I went with basic water proof MG Chemicals Silicone Conforming Coating on the boards, drilled out the small fin on the heat sink to add a 4mm aluminum tube for water cooling and about to add some MG chemicals Silicone Heat Transfer Compound between the tube and the heat sink. The tubes fit in snug, trying to see i I am missing anything on these escs?

They will each be running Ripple Killers’ cap pack which run great on my speed cars.

What kv motors are they ?

For those with little experience with ESCs, let me confirm that the OP’s cooling should work fine. It is almost identical to the Castle Hydra series, just with one pair of lines instead of two. There are more efficient cooling mods which involve removing the extrusions, but for a simple mod it will work.

For years I ran a heavy P Sport Hydro with a Neu 1521/1.5D and an aircooled Castle ICE 200 controller. I simply installed a 40mm computer fan on top of the ICE using zip ties and completed well over 100 race heats with 100% controller reliability. No water cooling.

How good is that

[Speedfreek]

Awesome, love the XLX doing a similar job for when the seaking 180's V3 give out, which will not be long with me behind the trigger

[Speedfreek]

Miltoggie, I can send you a link for good caps if interested. If not, just disregard. That’s a nice cooling mod, I applaude those that “go beyond the covers”!

I would love the link to the caps please

Can I ask what voltage you will be running? You posted excellent pics, and I invite folks to note the voltage rating. Those are 35V caps on an ESC that says 8s. That’s just not enough margin for 8s. I would recommend using 50V caps on 8s for more voltage headroom and make it last longer with the ripple current.

I think it’s sad these ESC manufacturers cut corners like that... I’ve had to change all the stock caps in my 8s controllers over to 50V. Note: only applies to 8s operation. 6s and lower should work fine, although the ESR on these stock caps is pretty high, meaning their ripple current rating is low...

Sorry for digging up old thread.
But I’m thinking about picking up xlx to run on 8s in my 8th scale hydro.
Are you talking about replacing all the caps on Board or leaving them and adding 50v caps?
Would mind posting a link to caps you were mentioning? There a Fry’s eletricronics store around the corner from
me.
