[RCprince]

lol you guys are funny...enough already....What is It we like about the SV...hmmm..I like that fact that I have an outboard on mine...waiting for the winter thaw to whip some cats behind.....working on stopping it from leaking when it flips....

Hey RCprince, what's your top speed these days? What motor your favorite?

Kin, you will like the Hydra, it's well designed, nice instructions clear and easy to understand.

yeah im sure to love it and it be music to my ears , sorry off tracking , thinking of getting the titan 29 hull and build it from there ~ not sure what electronics to store in yet tho , still in the drawing board stage

I liked to hear what kind of speeds you guys are getting when done with your mods. I will be interesting.

I'm going to have to get a GPS then. More $, ugh. Kin, try a Feigao, they are a nice upgrade. The AMMO 2300 is a sweet upgrade to. They are sold by OSE. Here is the link: http://www.offshoreelectrics.com/pro...od=dh-gpmg5290

If you want something that is close to the Feigao 540 11L 2,234 RPM / Volt 5mm Shaft. 540 10L 2,458 RPM / Volt 5mm Shaft

As of now they are out of stock, but once in stock it's a great upgrade!

I beleive RcPrince is way over 40, even 45+.

I noticed the same thing you did when I was cleaning out the obstructions in my cooling system. When I had the heat sinc apart I bent the two pieces back out the other way so they were concave. Then, during re-assembly, I tightened down the screws in a uniform and gradual manner with blue locktite. The heat sinc/cooler now sits flat on the top and bottom of the ESC.

I'm glad someone saw what I'm talking about. But anyways I abandoned the stock ES for a Hydra 120. I never even used it!

Kin disregard my PM. I didn't read the entire thread before I sent it.

I know this thread is kind of old, but I noticed that mine is this way too. I bet they all come from the factory that way. It doesn't seem to matter how tight or loose the screws are. I can't imagine that it works very well this way. Probably just needs to be bent a little so that the heat sink actually touches the ESC. Or, just buy a Castle ESC!

[SweetAccord]

That was my solution a Castle ESC!

hello, i had the same problem with the esc overheating but what i did is i went to radio shack and i bought ( Thermal Grease ) and i applied it in between the esc and the cooler, Thermal grease conducts the heat transfer better and up to now i have never had a problem.

You can do that, but the idea behind thermal grease is not to act as a "filler" if there is a noticeable gap, rather it's to provide a "better" contact on top of an existing "good" contact. If your heat sink is flat, adding the thermal grease will definitely help like you already said it would.
