Default Scalextric Ford GT Conversion

As promised, here are the step-by-step photos documenting my conversion of a Scalextric Ford GT to run on the SCX Digital System.

As you know, this is the car I decided to convert:
FORD GT .jpg


I assessed the "closed" bottom of the chassis.

With the body off, I assessed what needed to be done ~

cSTEP 002.jpg
dSTEP 003.jpg
eSTEP 004.jpg
fSTEP 005.jpg
gSTEP 006.jpg
hSTEP007.jpg
iSTEP008.jpg
jSTEP009.jpg
kSTEP 010.jpg
lSTEP 011.jpg
mSTEP 012.jpg

At this point, I wanted to make sure that everything thing that needed to be secure was secure, and everything which needed to move, did indeed move properly. I neatly taped the motor leads in place, removed any remaining dust particles from the cavity, and as you can see, hot glued the chip unit in place (I like Matt's idea of screwing it down, but cannot find the right screws to do so). I guess...

And after all was said and done, time to put up...

For this initial test run, I ran the car with the body off(as in photo) to carefully watch the action of the solenoid arm and guide and such. In replacing the body, I found no detrimental side effects in handling, and the most enlightening observation I made, and I should have realized this during step 12, is that you do not need quite the headroom we all anticipated and fretted over for the solenoid arm to operate properly. It's upright, static position is as high as it goes. In the future, I think more concern should be placed on feasible distance for arm's reach, and width for the chip to sit at the correct depth, that actual hood height.

I'd be more than happy to answer any questions you may have, or explain any procedure more in depth, but hopefully, I covered each step in depth.
In the meantime, I'll be mulling over the options for my next conversion model...

Very nice post and great instructions, Len. This is most definitely a car that I will be converting in the future.

Question: How did you mount the chip assembly?

I very simply, hot-glued it in place from the rear of the chip housing, Matt. It held fast, however, it is only temporary as I'd like to bracket it in place as you did but cannot for the life of me find a viable screw. What type did you use?

What I may do is mass produce an aluminum bracket which would be something of a double reverse "L" which would firmly hold the chip in place without a screw. It would fit perfectly over the top of the chip house, 90% down the rear of the housing, and reversed 90% angle flanged out upon the chassis, with the only necessary screw being into the chassis itself.

I say "mass produced" because I am dead set upon one design which would work in any and every situation.

I have a diagram of my intentions at home which I do not have at my disposal at my office to show you right now, but will get it to you.

You'll have alot of fun converting this car. I am considering as my next conversion ~ a classic 'Vette... yellow, of course

I can picture the double reverse L bracket and it is a good idea. I've been wanting an excuse to get one of those computer controlled plasma cutting machines I see in the back of Popular Mechanincs...

A yellow 'Vette? Do you happen to be a fellow yellow junkie too?

I LOVE yellow cars... I must've been a cab driver in a past life!

Anyway, I'm glad you concur the "bracket" is the way to go. We'll standardize this yet!

Sorry, I forgot to answer this question. The screw was just a short, pan-head screw I had in one of my bins. It fit perfectly in the hole Scalextric used to mount the car to the display box. Note the washers I piled up as spacers so the screw doesn't extend past the chassis bottom.

As I pondered your statement of using hot-glue, I decided that this may not be such a bad idea for several reasons:
  1. It is easy
  2. It is secure
  3. In the event that the chip must be removed, I have to de-solder the motor leads anyway; hot glue isn't that hard to remove.
  4. Being such a flexible solution, it should work for any situation.
  5. It would be the lightest mounting solution.
Thoughts?

I haven't looked at everything yet but it appears to be a very detailed conversion How-To. Good job. I'll take a closer look in a bit.

Default ARS guide hole size: updated

I forgot to mention this is my step-by-steps:

When I drilled the hole to accept the ARS guide, I drilled it at 1/4", and have it listed as such. However, I found it to be slightly tight, so I re-bored it at 9/32"


ARS Guide "hole" size: 9/32"

It's about time this was bumped - maybe topped. This is an excellent tutorial.

How is that hot glue holding up Len?

EDIT:
I see how the new axles are attached to the chassis but how are the front wheels held onto the axels/screws? Do they spin at all?

Only if I'm allowed to use "stick figures" here and there... lol

Thanks for the kind words. I'm just happy you enjoyed what I'd written.

Being new here the whole idea of conversions seems tricky, but a challenge. Has anyone tried, or heard of anyone trying, to convert a Carrera COT over to SCX Digital? I know SCX is planning to release the COT's in the fall, but I need a project............or at least another one!!

Len,
Does she change lanes for you? I looked at my SCXd cars and the guide sits deeper than the rest of the chassis floor. With everything level, my conversion could not push the guide switch deep enough.

The COT's will be released before the fall I think.

Sorry it took so long for me to answer Danni, but I haven't had much time to come out here and check the boards the past couple of weeks.

Anyway, yes, it does change lanes perfectly.

But truthfully, I'm with Dave and Brian from BRS on this one - I'm waiting for the SCX releases instead of attempting any more conversions. I've done several and not only are they a major headache to get working perfectly, but also, as I wrote in another post - very costly. If you figure in the cost of the car, conversion chip, axle & front end, replacement motor - it's just not worth it. Besides, I really, really, REALLY like what SCX is releasing, so why go elsewhere?

I've converted several car successfully and proved to myself it can be done. Now I'm done . When it comes to conversions, I'm saying what General Custer should have said... "I've seen the indians - I'm goin' home!" Len
