Is this Schulze Esc Any Good For Boating?

Just trolling the net and found this. It is an aero version not the watercooled one.

Yes there are and they make a watercooled version of that speedo as well. They are still good high end esc's with the proper set-up and component selection.

I bought a NIB one for $100 shipped yesterday evening!

Would like to know more about either using conformal or corrosion X on it. I have corrosion X already. Will be ordering a pistix for it too.

Here is the link where I found it and bought it.

You will not need a pistix for the Schulze, the DIP switches allow the user to set it up for either ground or air use.

Although conformal coating is optimal it is difficult to do correctly. You will need to mask off the DIP switches, 5V ISO plug, USB plug, etc. I would just stick with corrosion X and find some shrink wrap to protect it.

As a newbe to fe Tyler THANKS!!! Great info and would have surely bought the pistix.
I have shrink wrap already. Was thinking of installing water cooled tubes on the heat sink???????

[RaceMechaniX]

You can try to add some cooling plates, but this will be so-so in terms of cooling. You could try to solder brass tubes to the sides of the copper board like Schulze do it from the factory. Take a look at how they do it for ideas.

Schulze was asked about soldering tubes to the board - they said not to do it. Too easy to warp or unsolder surface mounted components causing permanent damage. A better solution is to add a fan to the ESC - as long as you have enough air volume inside the hull. I use a 25mm computer fan on my Schulze 32-170 controller in a Q Sport Hydro and it works well even on a 95*F day. I'll try to find a photo later.

Ok fan it is. How do I hook it up and where can I get one? OH thanks!!!

Great find!

I got my fans at a computer parts store, but they are available on line too - even on eBay. Type 25mm, 12 volt. Below are pics of how I installed one on my Schulze. I wired it straight to the battery wires where they contact the board. Shrink wrap holds it in place and provides the ducting. It blows through the controller.

VERY nice. Did you treat the esc with corrosion x or something else also?

Hey Guys,

as fluid says Schulze doesn't solder water cooling tubes to their ESC's cause of the risk to unsolder any other components. And they also say they do not recommend to try.

I don't know if for the new futures the air and the water cooled versions are the same (you may post a detailed picture) but I know it was done for several of the old Schulzes to glue the water cooling tubes to the PCB where they are normally soldered. It may sound a bit crazy at first but for example for the use in normal PC's and Heat sinks there are very special glues available with a very high thermal conduction coefficiency. Might not be that cheap but really worth a look and it has been done succesfully for Schulze 40.160 and 32.170 of the old series. Adding an additional fan like fluid is not a bad idea either.

Best regards,
Manuel

tnks Manuel, I am positive that JB Weld will both hold it and conduct heat too. It is a epoxy 2 part mix compound used here in the US to even patch engine blocks on cars. Water cooling would be simple vs the fan method so must now decide which I want.

[RaceMechaniX]

Do not use JB Weld, it does not conduct heat well and in fact it may insulate it. You need thermal paste or thermally conductive epoxy. It will probably be best to just add the fan as suggested.
