Using a Castle ICE Aircraft Controller in FE boats

[Raydee]

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.

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.
