Great thanks

Can you guys tell me this the power rails in the picture are electrically isolated from one another? What I would like to do is make a extrusion just like the other side of the controller and mount water tube to both sides. My concern is that if I bridge the pos and neg sides of the controller with the extrusion that it will short out the controller.

I also received two of the 200 lite controllers and they appear to be built differently. One has some type of tape on the neg rail and the other has nothing. What kind of tape is this and can I just remove it to add the watercooling?

Just glue extrusions with arctic silver epoxy like the way everyone else is doing and it will be fine since it the epoxy isn't conductive

Wanted to post some pics of the aluminum cooling plates that my buddy made for me. First test today went great, really made a huge difference in cooling.

Thats pretty nice, did you make the metal yourself?

[Raydee]

They were machined out of a block of square aluminum tubing.

Nice job Ray.

Can't take any credit for these except maybe being the Guinea pig that tried them first

Vary nice.

[dmitry100]

Raydee, how much did you pay to get those made? And who :)

I can’t wait to get my air controller and do this mod. Years ago I bought some cheap (china as they get) esc’s, they were so dinosaur looking the boards were stacked with rods it was caged looking and they cogged really bad on startup. I remember completely coating the entire thing in JB and after that cured I JB’d on aluminum tubes and when the tubes cured filled in the rest of it with JB. I never even used it and gave it to a friend.After 11 years and over 100 hours of used it still works great!

Torque Roll with a twin when turning at speed.
If you have your props turning inbound, you will have problems turning at speed.
When you turn the outside motor loads up in a turn, and the torque of that motor is now trying to rotate the boat even more to the outside, causing a flip.

This is why I run my props outbound on my twin race Cat, when the outside motor loads up in a turn, the torque of that motor is now trying to hold the boat flat on the water.
I have found that I can now turn at almost full speed. My "Q" Cat runs at a full speed of 70MPH.

The top speed of the boat would be a bit faster with inbound props in a straight line, but cannot turn without slowing down (FLIP)

I do not know if this will work,
Above is a old video of my cat , when I was still setting it up.

The outside motor in a turn will never load up , the inside is what “amps/loads up”

I’m so ready to put a cooling tube directly on this part.. thin layer of JB and then brass tube right on it

I am not sure JB weld is the best for this application. You want something that is specifically designed to conduct heat (thermal epoxy). I've used this product with good results.

I was talking about large CAT's in my statement.
The outside motor will load up in a turn at high speed.

On the my quad drive if I did a bunch of right hand turns at end of run the voltages on my 4 batteries would always read lower starting from the right side of the boat and go up in volts as I went threw each separate system , the battery driving the prop that found itself on the outside of the turn the most would always read higher voltage. That’s why I say the inside was loaded because the prop/system running inside of the turn always consumed more power. That’s my understanding of loading, kind of like a positive differential the inside seems to over torque and slip and the outside tire wants to be pulled threw the turn. sorry if I’m not getting it !

Maybe in your Quad drive.
I am talking about a large light Twin Cat for "Q" Racing.
In a turn at high speed (over 70MPH) The hull tilts to the outside ( opposite of a Mono) therefore loading the outside prop more.

This is why I always run my setups so that both motors see both batteries, This way toward the end of a race, the inside motor does not have more battery causing the boat to want to turn left when the steering is center.

Also for racing, I recommend running your props outbound NOT in bound.

When Outbound - when the outside motor loads up.(deeper in the water) the torque of that loaded motor will try and bring the hull back to flat running.

That makes sense, thank you Larry .

Ordered the Mamba XLX today, I’m going to leave it factory with the fan and going to add water cool to the factory heat sink housing, I’ll make a couple water cooling plates that go on the side probably attach them with thermally conductive Yamabond gasket maker or might even just JB to the side. Price point was better with this esc vs the air controller and will work out of the box with my old DX3S radios. Going to use the IOS Bluetooth programming implement also . Castle said they are working on the telemetry program for iOS still but that’s coming
