For me, the bottom of the car needs to be smooth and not cause turbulence. If that means covering it with tape - so be it. I like paint but sometimes my car is already on weight and I have to do something without extra weight. Clear tape can do the job without much in the way of weight gain.

I would like to learn more about under body turbulence. How much does not having a "smooth" underside effect times ??

I haven't a clue as to how much difference it makes, but if the difference between second place and winning is a few thousandths, and there is a way to get those few thousandths by eliminating a little turbulence what would you do?
In the KOH, one of my cars tied in the final run and won in the run off by about 2 thousandths. Second place didn't get a check for $400 - was it worth it to pay attention to "little" details? I think so.

And being one of PDDRs fastest (not mentioning any names) doesn't hurt when selling a league car on ebay for $500.

what ? who ? Ok it was $499.95 with free S&H but it's the highest price I've seen since the car, "Casino" was resold last year on ebay for $400 if I remember correctly. I won't disclose any more than it was a very fast car from the 2008 PDDR season.

Here's the bottom of Viper
As you can see I've carved it out fairly deep. Weighs about 25grams, but I think I can go lighter.... I am not sure that clear tape will have enough on the rockers to stay put.
Any ideas or suggestions ??

You could use a very thin sheet of balsa and make a cover. Put some small ribs running through the middle of the void for support and glue on the cover. Or you could cut some Styrofoam to fit the void so that it is flush with the rest of the underside. Glue it in and use some tape or even a cut down bumper sticker to put over it. When I redid the guitar car I dremeled it out in a honeycomb type pattern and used some thick paper and Elmer's glue to make a skin over it. If you wanted to use balsa you could pick up one of those small balsa airplane kits. You know the ones with the rubber band that you twist up with the propeller. The wing might work for a cover and you could use the frame to make the ribs to span the void.

You could use 1/64 hobby plywood or monokote. Monokote can be ironed on and made banjo tight with a hair dryer or heat gun. It's light weight, comes in many colors, or it can be painted. www.monokote.com/The trim sheets might also work. www.monokote.com/trim.htmlHope this helps!

Great info !!
I've never used Monocoat before, read the web site info & it sounds like it could work.
Thanks "Santa Bones"

Well...... Tried to cover the bottom of Viper RT10 with some Monocoat.....
Used an iron on the edges to stick it down, then a hairdryer to tighten it up.
Let it set all night, when I checked it this morning, the edges were 'curling' & the front curved 'air scoops' had lifted......
Gotta be operator error..... having never used this stuff before. I'll give it another try after work tonite. [/color]

[/color] [/quote] Fast I have used monocoat before and I have always used it on bare wood and it was easy to apply and stuck very well. I don't know how well it sticks to painted surfaces. Might want to try on bare wood and see if it helps. I do what you did by sealing all the edges with the iron then I have used a heat gun to shrink it more to make it tighter like a drum. Once it is applied it shouldn't change over night or loosen up for a while.
