Crusader Tank new build

This section is for builds that are not strictly Tamiya or Heng Long. For instance, replacing the electronics from a WSN or Matorro, or even a scratch-build.

After producing the Matilda and having viewed many videos of the North Africa campaign I decided to take a look at possibly designing a 3d printed Crusader.

As this tank uses a Christie suspension, I am hoping to use existing suspension arms/springs from an existing HL tank to save me having to develop them from scratch, plus they will be stronger. What I need to know is what HL tank has suspension arms approximately 30 mm long? Perhaps someone out there with a squadron of tanks could check and get back to me please (and if possible if they have a spare plastic arm and spring in their scrap box could they please let me have one - happy to pay any postage/packing costs).

Had a quick look around the 'toy cupboard' - KingTiger, Pz 3 and Pershing/M41 look to be too short, and KV too long. Don't have a HL T34, but the arms on the WSN ones seem to be closer to 25 than 30mm, as are the ones on my Panthers.
Challenger 2 looked promising, but having pulled the arm off it measured 27.5 at best...

Hi Tiger, 27.5 is probably close enough, so I just need to find some chally2 arms now. Thanks for the help on this, much appreciated. :clap: :clap: :thumbup:

Hmmm, this isn't looking straightforward at all, so may change tack and go for a Churchill. I know Ludwig does a kit but I priced it up once and it added up to about £750! I have shied away from the Churchill as it looked complicated, but compared to the Matilda it will be easy-peasy. I have mastered the sponson issues and the Churchill is far simpler than the Matilda. The other thing that has held me back in the past is the narrow chassis and getting gearboxes to fit, but I think I have probably solved that problem.

So watch this space :D :crazy:

If it’s of any help Ludwig has 2 versions of suspension that can be used on his. The tiger 1 or his own

I'm still trying to get my head around what to build next. The main thing with both the Crusader and the Churchill is finding tracks that would fit. The tracks on Ludwigs model look nothing like the Churchill tracks, and the closest I can find in size terms are the ones from my Centurion and Chieftain builds, which were KV-1 tracks with the edges trimmed off, but again these don't resemble the Churchill tracks in any way. The Crusader tracks are very narrow, and the closest I could find would be Panzer 3 tracks, which I used on the Matilda. Hmmmm, what to do? :/ :crazy: 8O

I struggled with tracks for my Crusader build - used Panzer 3 then ground down the sides. Scale tracks should be 17mm wide - my cut down ones are 19mm. Bit of a tedious job as had to be done with Dremel cutting/grinding disks.

It had a very low profile (not much over 7 ft tall), making it harder to target, and displayed early adoption of sloped surfaces- but one in front of the mantlet would certainly have helped. Also, I suspect the Inward sloping turret sides might have directed incoming rounds to vulnerable deck/roof plates. :O
But for mechanical woes, which could have been resolved and time been available, and HE-capable 2-pounder rounds it would have performed better than it did in the desert. In the event, it showed the Italians the way home and had early successes against the Afrika Korps.
A six-pounder- at the outset- and with which it was equipped later, would have given it plenty of punching power too.
Like you, Kaczor, I think it's a pretty neat design- notwithstanding its service history. :problem:

I thought DKLM RC had Churchill tracks since they do the 3D printed Churchill?

Just discovered this, I'm not sure it will work but I'm going to try it

For £3 it's worth a shot!

That track is double guide tho, the Crusader is a single center guide horn.

Yup, I have decided to wheel out Openscad and design my own. 8O :crazy:

Honestly I'm inclined to go with cut down Pz 3 tracks, the Panzer IV sprocket is only slightly larger than the Crusader's

Looks like this - just have to print it

At 11 minutes per track thats not great but maybe I can print thicker layers and reduce that without quality issues

Well they printed pretty well and even in PLA+ they are pretty strong.

Joined them with dresmaking pins and they look and work very well. Looks like a way forward! :thumbup: :thumbup: :thumbup:

Hi Alwyn,
the track link looks terrible.... stringing without end and the filling level is too low.
But I think they are prototypes. :haha:
