Ultra modified SV 27 pics ...

[hex-dj]

I am currently using an AMMO 2300Kv , octura x438, feather weight carbon gears servo, hallowed some aluminum parts to make it lighter ,sharpened 2 blades and fins,14 cells, 2000 Mah ,4/5 sub-c cells ,Novak 2700 mf Power capacitor in stock ESC. Boat GPS ed 55 MPH...Very ,very fast! Motor and ESC got slightly warm.I ve got pics too. I ve been running R/Cs for eight years now. I also have a Black Jack 26 modified too. Checkout the Black Jack 26 EP forums too.

Pics of my Ultra mod SV 27 EP...

Full throtle ...

Second pic.. HAHHAHA ..ooops all my boats are drag race ready thats why they excel in speed with cheap set ups... imagine something more expensive,but way too heavy... Hahaha...Videos coming soon.

I also use rain X ,believe me it makes boats faster.

[Jedi Master]

Looks awesome, get that video posted!!

I also use rain X ,believe me it makes boats faster.

sorry nope.
running the full size hi performance boats i know first hand "rain X" will not help.

[hex-dj]

Realy well I ve tested it and no salt sticks to none of my boats ,because it works the same way it does on a windshield in any polished paint. Why you say it does not help? Can you please elaborate on that?

[FeGateKeeper]

How exaclty is it helping you out? Are you using it as a protectant or for a performance gain?

[hex-dj]

Both ,because I dont get any salt under the hull first and second it makes the hull repel water under the hull like it repels water in car paint or in a windshield crystal making any boat big or small faster, dont know how much speed it will add to boats exactly ,but I ve seen speed increse with my eyes and gps differences for example without it, my sv 27 looks slower and gps ed only 52.465 MPH when applied it GPS ed 55.0 MPH following the water stream both times when gps ed. I can imagine a Hydro or a Rigger with this kind of setup. I use many drag race principles even from full scale drag vehicles or boats. I will be getting the new Miss Elam brushless RTR when it becomes available. I will try the same setup Im using with both my SV 27 and BJ 26 EPs RTRs. I get very fast speeds from any setup on any R/C... Sometimes expensive doesnt mean faster,but sometimes setting up right takes a bit of time and testing.

These are my opinions and not fact, so feel free to correct me!

from what i hear... you need a slightly rought surface to trap a very fine layer of bubbles on the bottom of the hull, to break surface tention between the boat and the water, and a smooth polished surface is counter productive.

maybe if it was to be used on a non running surface it might help clean up, you say your running on salt water?, i would like to see the speed difference on fresh water, i'd be surprised if you came close with thoses speeds.

Apples 1, Ask yourself this question... Why do we need to polish propellers? Is it to make them spin faster or just to look sharp and shiny? Same thing happens to paint when it is polished according to my experience.

[hex-dj]

Take a look at a full scale race boat and look at the bottom of the hulls.

Having been in the F1 boating scene for a few years in a pit capacity, there is not a single race boat that has a shinny painted running surface on the Aussie Circuit.

I'm not sure about the rain x qualities but if you put Mr sheen on a RC boat it is slower than with out it.

What does everyone elses expierince show? what is the consensis, a poll would be nice.?

[hex-dj]

Yes a poll will be nice. Well rain x may actualy add weight and repels all water,but scuffing as far as I understand makes a boat stick more to the water in my belief, I think a good engineering and paint class will help.

It's a fact that the smooth surface creates more drag by increased friction. It's also a fact that a 3mph difference on gps can be no gain what so ever. The gps reading is based on avarages not exact ground speed. The stop watch over a marked distance is the only true way to mark your speed.
These are not opinions. This is information givin to me by guy's who have forgot more about rc boating than I ever hope to know.
