VK 16.02 Leopard

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.

Hi all,

I start this topic to document the construction of VK 16.02 Leopard. The Leopard was a German prototype of light reconnaissance tank, finally canceled and no prototype was built (more information here).

This model is going to be my first build "from scratch", and I have chosen it by several reasons:

  • It is a relatively small tank, with a length of about 30 cm (without the barrel).
  • With the exception of the turret sides, no armor plate has curvatures
  • I have the blueprints.
  • Suspension is very similar to the Panther, so I will use the same components from Heng Long Panther.
  • It's exclusive 8) (I've seen only only one RC in this video).
  • As it was never real built, it gives me the freedom to improvise/change certain parts.

Regarding bibliography and documentation, my primary source will be "Panzer Tracts 20-2 - Paper Panzers" book from Jentz & Doyle, where it has the original july 1942 blueprint. Additionally, there are other more or less faithful references to the original drawing:


To help me in the construction I have chosen to model in 3D, using as reference the original blueprint. Some considerations:

  • I'm using Onshape as CAD software, and you cand view the model here.
  • It is made as independent parts, perfect for taking measurements and to move to he mateeial or even 3d print them.
  • I'm learning CAD, therefore operations and/or methodology cannot be the most accurate
  • The model is fully under construcction, there are draft sketches, redundant operations, duplicate parts, etc. I don't guarantee that all pieces have the same dimensions from one day to another. I fyou have doubts, ask me without problem.
Ok then but, what will it lool like? It should look like this :D

Hi again,

One important thing. I started the construction few months ago and there may be discrepancy between the uploaded photos and the current model in onshape. If you are really interested in the chronological order, ,please visit this topic in the spanish forum La Cadena Herrumbrosa. A lot of spoilers inside!

Cheers.

Doubtless, many here will be curious to see how this build goes along, Edumardo!. Builds of rarities are especially welcome, I'm sure. :thumbup:

Thanks for the links, I didn't know some of them ;) . Another one that has inspired me and I forgot is this model for War Thunder game:

Hi,

Since I'm going to use the suspension parts of Heng Long Panther, I needed to get the measurements of the swing arm support, both the hole with screw and spring and the rectangle to simulate the torsion bar effect. I have modeled taking as reference the Heng Long plastic model:

I have one type for you, arched tracks for the movement of the shoulders, the cutout, do longer than the original, I once grinded these tracks on my first tank, which serve as stops for the movement of the shoulders, and made them much longer in the plastic tub, movement, suspension and behavior the chassis has changed dramatically ...

Hi LK88. If I have understood properly, you have enlarged this gap, right?

Hi all,

Because I'm going to use the classical gearboxes of Heng Long (long shaft), I also modelled them for place in position and take care of distances, support structures, etc: This 3D model (right side gearbox) fits on Heng Long Panther G:

A unique and interesting project, Edumardo! I'll be following along with interest, your CAD drawings look great. Looking forward to seeing more!

I've always thought that the Luchs is like a baby Panther and the Leopard is like a baby KT. ;)

WoW, fantastic job! You have set the bar really high ;)

It seems you used a panther hull trimed, right? What about the turret? Is It from scratch? The wooden barrel is a very good idea for this inusual model.

Thanks for sharing, It Will be a reference without a doubt.

Hi there Edumardo

The Hull bottom and bavk plate were the base for the build ... as well as the engine deck

The turret is scratch built from plastic card as is the rest of the Hull

Fortunately the bk 16.02 is a fairly simple build but the secret is the detailing that makes this

I remember enjoying the build.. and the model now lives in New York in a collectors privet collection

Ps the gun barrel was actually a modellers paint brush as it had a nice taper ....

Hi,

Continuing with the suspension, the layout according to blueprint is sprocket + 5 overlapping wheels (2 doubles and 3 singles) + idler (copyright in the picture):

img_2016.jpg

To ease the building, I will choose the following configuration: sprocket + 5 overlaping wheels (3 doubles and 2 singles) + idler. Hence I don't have to worry about the interference between the last overlaped and idler, and it will allow me to use the standard heng long tracks for Panther:

img_2015.jpg

In other words, a layout almost identical to Panther. Furthermore, and this is my personal opinion, beacuse it was a initial design of M.A.N (derived later to MIAG), we can assume the reuse of parts and designs from the Panther in its different versions. It is not unreasonable to think that if the Leopard had entered in production, it would have followed an evolutionary path similar to the Panther, inheriting and feeding back the improvements. This last guess will help me to take decisions based on the parent model.
