Just wondering if any fellow TC members shortened the wheel base on their CR-01 (especially the rear) and if so how did you do it?

Mine has a wheelbase of 276 mm. To shorten it I made new links using threaded Rod and SS tube ( or alu, i don't Remember). I'll try to find some pictures...

Unfortunately four years have passed and I can't find the measurement I used. But  I cut three different parts in lenghts, therefore I must  have used  just one original link.

for fine adjustement probably I switched from original Tamiya uniball to traxxas uniball, but I'm not sure... photos don't help.

To complete the link  normally  use threaded rod 3 or 4 MA . I cut the rod 16 mm  longer than the tube and screw the uniball

for example, self made link for HPI Venture

I pulled up @mastino's first image in Matlab. Granted there will be some artifacts because it's a real world image, but he got a good top-down image without much distortion. And taking the photo with the ruler was key.

Measured the the ruler twice and took an average to get:

>> mmPerPixel = mean([(170/701.11) 170/712.02])
mmPerPixel =
    0.2406

Then from that (using the measurements from the image) define:

>> shortTube = 186.65;
>> midTube = 250.18;
>> longTube = 254.07;

And from that calculate:

>> shortTubeMm = shortTube * mmPerPixel
shortTubeMm =
   44.9108
>> midTubeMm = midTube * mmPerPixel
midTubeMm =
   60.1971
>> longTubeMm = longTube * mmPerPixel
longTubeMm =
   61.1331

Those numbers look about right. Cheers to @mastino for the images illustrating his process.

So it turns out the numbers are 55mm for the upper rear and 53mm for the lower rear to move it forward by about 15mm

i will find out once my kit arrives and I get building
