NeverWet for ESC's?

[Cooper]

Yea, lol,, my boat has been flying a lot lately!!! Takeoff speed seems to be right around 105mph. But she looses flight quickly and goes out of control once airborne. Maybe I should dimple the whole hull?

Lmk when boats start flying then

Seriously, your google elplination is spot on of what I said to start with, read it again. The dimples create a disruption in a normally stagnet airflow. My explanation and what you refered to are of the same. Sorry but you can't argue with factual evidence supported by overwhelming factual data. I'm not trying to be right but simply giving you the facts. And in the early days of golf most of the balls were hit dead. No spin, get your information from something based on factual history and evolution of the sport. Do what you want and believe what you want. But I will only give my opinion on factual established I formation unless otherwise stated.
Smooth and flowing lines above waterline and sharp square lines below for our boats, period !!

lol ok...

actually very similar, its all a part of fluid dynamics.

Who gives a crap what golf balls do? They're moving thru the air, not across the water. Two completely different elements.

[ls1fst98]

golf balls get quite a bit of rotation, so idk how you say thats why they have dimples. and a sharks skin is far from smooth, only feels smooth to the touch in one direction, look at it under a microscope and you will see. http://entertainment.howstuffworks.c...question37.htm here's the explanation on the golf ball. large ships want smooth because they have no real separation from the water surface like a planing hull. the rough surface would allow for tiny microbubbles under the hull which is less drag on the hull then smooth water.

[Cooper]

And this is the only place I know of that the racing world believes rough surface is faster. World class race boats and world economic shipping companies invest a lot of money to make their vessels more slipstream. (Paint, coatings, shape ect. )

[Cooper]

a rough surface works better. look at a golf ball, its designed with the dimples to make it fly farther, straighter and even correct slice and shank. dimples do work better for some reason beyond me. more so look at a sharks skin, quite rough, yet very efficient at slicing through the water.

Oh boy here we go again , lol,,, yes on the golf ball but the reason is wrong. The dimples were established on a golf ball because they were hit dead, no rotation. On a dead ball the dimples will create I consistencies in the airfoil allowing greater flight distance and accuracy.
Sharkskin, completely different, fish have scales, sharks have skin. Like mole hair on cross country skis - directionally smooth as opposite rough. And very seldome addressed in fish is the mucus membrane (slime) that effectively negates dragg (from scales or skin) dolphins are similar

I still don't understand why people think a rough surface is more hydrodynamic. But I originally purchased this by the parent company and it depends what your uses are. When properly applied it has the feeling tacky felt. Water does need up and run right off but it is a dust and dirt magnet. Can be scratched very easily. Comes off with many solvents, naphtha,xylene , acetone ect. I sprayed a hull and ran once then wiped the whole bottom off with xylene. Left it on to to help repel water but it has very little left after a couple months of handeling. But it is good stuff just not as durable and speed oriented as we would require for our hobby. Now that the price is way down from $200 for a quart (top n bottom coat) get some and try out, Im positive anyone can find many uses :)

I posted this earlier but more geared toward the bottom of hulls. I'm sure this would work well for ESCs, Rx and servos.

I'd try but mine are already waterproof.

For hulls, it might be better to have a slightly rough/primer'd bottom...JMHO.

Actually I meant in relation to your OP, not to be applied to electronic devices... like esc's ?
Still worth a try I guess. Not available here though, unless I'm willing to pay 70 bucks incl shipping

I think it's now being sold by Rust Oleum...
