Ok . Cool! TRUNKMUNKY. Soon I will post mines after my radar gun arrives of course.

Super flipper at 44mph, http://www.youtube.com/watch?v=Tf-hhyeCOws
Im a surfer and have shaped my own surfboards for years.
Here is my opinion on bottom surfaces.
Gloss=slow (buffed fibre glass high shine)
Wet rubbed=fast (400 to 600 grit sanded fibre glass)
Friction free finish=fastest (this is done by spraying a clear coat of car acrylic through a spray gun mixed with talcum powder with a very dry finish (minimal thinners) The acrylic dries as soon as it his the surface. Leaving it with a feel similar to a sharks skin.

Man I just read this whole thread and all I have to say is WTF MATE HAHahahahahhahahahaahahahahahahahahahahahahhahahah ahahahahahahahahahahahahahahha

That issue was addressed a looooong ti me ago.kck741 and SouthOzSV27. I know that what you say is true. I scuffed my bottoms a looong time ago. Suffed=faster. Looks like you guys are catching up with the forums.Thanks for looking though. :-)

Ever get a video posted hex? hows that radar gun working?
Huh,Since I drag race I dont care much about run times. I care more for voltages. To add at least 5 MPH to any R/C you need twice the amount of mahs for example ..say you have a 4000 mah battery ...in order to add at least 5MPH more to any R/C you will need double that amount. You need 8000 Mah just to add five more miles per hour so to me mah doesnt count much and its why I look more for Volts than anything else..though good run time is also appreciated Chiro.Oh and not to say that a 4000 mah batt. is twice lighter than any 8000 mah out there. Voltage can add at least 10+ MPH per NiMH cell... Thats why LiPOs only come in 2 cells three, four or six,because their voltage amount per cell is more than any NiCD or NiMH.They are around 3.7 v a cell ,while NiMHs are 1.25 sometimes more than 1.25 each cell.It also depends on your ESC too. A LiPO may add more than 10+MPH per cell,but who s going to have a 12 cell LiPO batt. unless you want your R/C to do close to 200 MPH.
Come to the FASST side
Let it go people...let it go
novak GTB's can only run 6 cell Nimh/Nicd or 2s lipos max.
i have a couple of electric drag cars i race and even on 3s lipos i've only hit 1.7's at 75 mph. mamba max esc with a 5700 brushless motor in a direct drive dragster. i can hardly keep the car on the road. everytime i run it it's a 50/50 chance i can make a good run. i know there's guys that have hit the 1.3's and i can only imagine how fast that is. a duratrax evader........................107.37 mph?? sorry, kinda hard to believe, especially on 8 nicd cells. how about some pics of the pro stock car?

i've done some test and tuning to my 2.5 index electric drag car and i've run with both 2s and 3s lipos. both are 2200 mah's. i got runs with a 27 turn brushed motor (trinity CO27) on 2s lipo's of 3.5's. when i switched to 3s lipos i've run time's within 2.5 to 2.7's. mah's don't give you more mph in dragracing.......voltage does. and besides, a 8000 Mah lipo weighs a ton. more than a 4600 mah 6cell Nimh pack.

Wake boards, snowboards and surfboards all have mat finishes on them.
In my experiance with surfing wet rubbed fibre glass is much quicker then fibre glass that has a highly buffed finish.
If your worried about protecting the hull.. or fibre glass do what surfboard makers do and mix talcum powder with acrylic clear and spray the hull (dry spray- so it dries instantly). This what they call a friction free finish.
Ive done it to my boat and flies. It feels like scales.
