Default IPS 2010 Cars: Work In Progress

Devious Dave sent me a couple of pictures of his entry that I'll post tonight if I can fix the home PC (does anyone know what's failed when it's a dozen short beeps spaced so close together it's almost a 1 second long beep then a 5 second gap?).

Dave has learnt a few things from this year and built a car to better suit the tracks than his current Ferrari 166. I know first hand how well Dave's cars go, he builds cars so easy to drive fast that I once borrowed one and beat him in a race. I'm predicting his entry will be one of the front runners in 2010.

My car will probably be the Strombecker D-type that I was going to use last year but it was so fast it didn't seem fair to use it. After seeing Dave's car I know I will have to improve over the E-type so it's now it's going to be how many races will Dave win, the Stig win and my car win?

Oh, you guys can tag along for the ride if you want to.

Cheers

Paul

Great job Dave, wish mine was as good looking.

Hmmm... It will be tough to find a wider or longer car within the rules. I've got 2 Ninco Classic Corvettes but I don't feel like cannibalizing either of them for the IPS so the search for a suitable entry continues.

The Ninco Jag XK-120 and Ferrari Testarossa are also very good cars to use for next year. I think they comply with the max width rule - 57mm.

You are all in for it in 2010, This year you will be running with me, and not with my VW. Earlier today I put me new ( Dads old car ) on the track set at 8 volts, 5 amps. I beleave he set it up for one of these races but never sent it in. Them Ninco rear tires were nice and warm and very true on them BWA wheels. You know this was only testing how fast the car will go for how long. We have Digital Carrera so the track is hot all the time.

nhdungeonracer will help work on the wheels & tires in his slotcar machine shop once I get the car to handle 10 volts without slipping in the turns.

My next step is to sand the inside of the body. Strating with the dremel and then hand sanding.

Starting weight of car with my dads setup 91 grams
Body weight 30 grams, chassis 61 grams
rear wheels max width (55 mm) running 52 mm

I closer look at the rear tires and it looks like 1/2 of the tire thread is worn off and started filling in the thread that is still on the tires. Remember we run rubber tires with magnet mostly so there is rubber on the track.

Nice looking Vette, I like the idea of the cut down windsreen

Been looking at these cars alot, one thing really sticks out to me

Stig ------------------ 10 ------------ 1 ------------- 698.8
Bopalou -------------- 6 ------------- 2 ------------- 684.9
Kidvoltage ----------- 26 ------------ 3 ------------- 665.5

You haven't said what car you will be running, is it going to be the T-Bird? Just make sure it's narrower than 57mm to make sure it's legal.

Body weight 30 grams? Try to get this down to around 15 if you can then you don't have to use much lead to balance the car. If you can get the total weight (including lead) under 80 grams you should have a good car.

Thanks for entering.

Cheers

Paul

That is a nice looking Corvette, to be sure. But couldn't he find anything more suitable than those Volkswagen/Porsche wheels?

That Corvette look familiar to me, was it built back in 2006 for another Proxy race?

Thought you might recognise it Phil. I copied the magnet map of Tassie (the island), and put it on the car as a memento. It's still showing with pride some of the scars from the Tassie Targa in 2006. The wheels in the photo are what is currently on the car as raced in classic races. The wheels on the model are what was on it originally, or, as near as I can get to them. Dave.

Hmm. Got my car together last night and ran some test laps... not as speedy as I had hoped, but handles like a dream. We'll see how she compares to the '09 CPR car when I get it back and go from there...

Hi all, been some time

I think my son was up late last night and one of my older cars was all in parts.

Up date on his car.

Quote:
Just make sure it's narrower than 57mm to make sure it's legal
Front fenders are 56mm but the front bumper sticks out to just a hair over the 57 mark, bumper can be removed easy

The scale was right here by the computer,
Newer body weight 25 grams
Newer chassis weight 52 grams ready to run, He cut the rear of the chassis right off,
11 tooth, looks like a scalextric pinion with a 26-tooth slot-it crown, seams to move very freely

For him money doesn't matter as I will buy him what he wants for this, but there is a very big parts box just full of my old parts, you name it & it's most likely in there. Setting here I am getting very interested and hope to help on the car.

So need to get the body weight down under 15 grams, WOW thats going to take some work.
I will take some photos of him working on it this weekend.

Here's a tip on getting the body weight down.

Use a dremel to do the initial grinding to get lots of plastic off the body.

I use the warm to the touch approach. Hold the outside of the body exactly where you are grinding and when it gets warm you know you have ground enough off. If the car body starts to go red and your hand hurts you know you have ground too much off so take things gently. I use quite a few different bits in the dremel to get into some of the tight spaces, especially across the back and front of the body. Spend a lot of time on the back of the body as you want as little weight behind the rear axle as possible. The same goes for the roof if you have a coupe or sedan as this really helps to get your centre of gravity down low.

Sometimes you may want to keep the front untouched to keep that part of the car body strong enough to withstand accidents but so far I haven't had any problems in all the proxies I've entered.

Occasionally hold the body up to a light so you can see through the plastic. You are looking for any spots in the body that are lighter (body is thin enough to let some light through). This is where you have ground enough off so don't grind any more there.

Use a coarse grade sandpaper to finish the job.

Using this technique I cut my D-type Jag body down from 30 grams to 15.

I also use lightweight interiors for all my cars. With the D-type the driver is cast into the body but it's only one driver and steering wheel, not a complete interior so I'll probably leave him alone.

You can also cut down the interior glass if you are really keen but all you are saving is 1 or 2 grams at the most. Hardly worth it unless you are cutting down a windscreen on a roadster (similar to what Devious Dave did to his Vette).

Have fun but remember to take things easy when grinding, it's easy to gat carried away and put holes in the body. You don't want that as body filler is heavier than plastic which defeats your exercise.

Cheers

Paul
