Looking for opinions on how much tape is typically used to mount side air dams on a wing car body? I have always fully taped the side of the body to mount the air dams, but have recently seen some above average drivers that only had a strip along the bottom (though they used a staple in the rear and at the nose where I do not use any).

 

All my stuff is flexi wing, Grp F or Grp 12, none of that big boy stuff.

 

Thank you in advance

I have always taped full side, but others use 1/2 in wide and it works very well, as for staples haven't used them in years although 15 years ago that was almost everything mounted that way. In Group F its all about the weight.

At a race recently I was treated to a lesson on body mounting by a couple of champion racers. They gave me a number of tips on this topic.

In general, using that special transfer tape, they put it down the entire side of the body, then apply the body to the side dam.

Having mounted my own based on experience, I have used various widths of the transfer tape in the same way, usually with 1/2" tape. However, they are using a much wider tape. When I did mine I needed to apply additional tape to the higher portion of the body over the rear wheels where a long time ago we would have used a staple.

about 3 months ago we had 1 or 2 threads going about cutting measuring and winging bodies. I will try to dig those up. There were some really good ideas and methods documented there.

The other bit of advice everyone throws in the ring is also good... Get a body that has been done professionally, and examine, measure, and duplicate what they have done. That's the slot racer way.

As an aside, I weighed my winged bodies and they came in around 9g. Joe "Chubby" Salzman told me they should now come in closer to 6g. And FWIW, I am running OMB and potentially H12, not that "Big Boy Stuff".

Whatever side gets the tape applied (body or wing), leave the d/sided tape backing in place. Mark off area(s) where pin holes will go (avoid these) then get a hole punch and remove as much material as makes sense to you

Then apply.

Out of interest, collect all the waste discs and you can use these for chassis packers - or weigh them to see how much you have achieved

I'd love to understand how 6g is possible, they must have access to some components that I don't...just the basics before assembly come to over 7g

And the finished article, built as lightweight as I can (just to survive one race) comes in at 7.74g

What kind of track are you running it on?

Just about any top Wing racer runs tape along the front edge of the air dam.

Albeit, these days, narrower and narrower.

The other thing is your air dams are most likely too long in the back.

By where your wheel well shows, next time, you may want to shift them further forward and then just trim the excess off the front.

BTW, those 6G bodies are .005" thick, and very short, for short chassis, on super high speed tracks .

What kind of track are you running it on?   Flat Track

Just about any top Wing racer runs tape along the front edge of the air dam. Yes I might add some.

Albeit, these days, narrower and narrower.

The other thing is your air dams are most likely too long in the back. Yes I trim these if they flutter, have to track test first

By where your wheel well shows, next time, you may want to shift them further forward and then just trim the excess off the front. They're Bang on for the club class I am running with this (JKX25 w/Phoenix)

BTW, those 6G bodies are .005" thick, and very short, for short chassis, on super high speed tracks . yeah, this is a .005 body and wings

The 6G body Chubb built, most likely had .004" dams.

 

That allows you add tape in right spots.

Aero, among others, makes .004" side dam air kits.

1241 is the one we carry, our wing guru, Michael Iga, prefers.

Below is a (well used) body by him.

From what I've heard, a lot of guys are using .003 side dams and adding ribs to stiffen them.

Dom,
Don't show him a car with those, or he might reconsider wing racing. Lol

For running on a flat track, they might not necessarily be an advantage, or good at all.

Wings on a flat track, in the U.S., not very common.

I remember running(hot lapping) a G27 with skinny tires, on a 165 ft. MTT.

It was fun.

I wish we would of tried having an actual race.

We race 2 classes of Wing here on Flat track

 

Club: any stamped Flexi from before the C43 was released, powered by a Phoenix with fixed 64p 11/35 ratio

 

National: Any OG12 Chassis with any G12 c-can, free 64p or 72p gearing

 

They are good fun races
