Prefect Fit!

First of all, I received my YGE ESC's today and these are the biggest (and most expensive) I have owned to date. Not convined on how effective the water cooling system is, I would have thought a metal plate on the fets with cooling water circulating around it would be the way to go. Here the brass tubes (one on each side) just seem to be soldered to the PCB and water simply runs through the tubes. Does the PCB conduct heat that well?
They are supposed to be good so we will see.



I installed the water intakes today which was about a 2 hour job. I did end up moving the cutouts for the intakes 2mm further away from the tunnel which makes the total distance of cut closest to the tunnel 5mm, thank goodness I did because they would never have fit otherwise. I still had to re-shape the intakes quite a bit to get them to fit properly, they are basically right up against the sides of the sponsons.







I sanded the surfaces, cleaned everything with acetone and glued them in the hull with the resin + cotton flake mix. They will stick out a little on the bottom of the hull but thats fine and will make it easy to get a nice flush finish.



The suggestion from Hanspeter is to cut the nipples off the intakes and drill the 5mm hole all the way through the intakes, then push a short piece of 5mm stainless (thin walled) tubing up through the intakes and attach the silicone tubes. He recommend not to glue them in but just seal with a little silicone, that way its possible to replace them for whatever reason.
