i'm tempted to get some of the lights, as they would be useful for turn signals or brake lights with the PF adapter, any idea if they have a orange flickering led that could be used as a light to simulate the muzzle flash of a MG. This could be useful if it could be controlled by a PF power and have the LED shining through rigid hose.

It should be structurally solid, if it is reinforced correctly in the frame around it. Where do you think the differential will break ?

the model is up on rebrickable http://rebrickable.com/mocs/TommyStyrvoky/xl-differential

Maybe utilizing a NXT, or EV3 to automate it.

here's some new renders, I am still working on improving them, right now I use LDview to render them. differential xl V3 by Tommy Styrvoky, on Flickr differential xl V3 exploded by Tommy Styrvoky, on Flickr

For some odd reason I forgot to have the newer color for the 5 long axles, the instructions have been updated, and I am preparing to upload this to rebrickable. Also I will begin designing a XL dual differential steering system.

welcome to Eurobricks, great model after 17 years of not building. What are the ratios for the gearbox?

It's possible to assemble without force, it's just a puzzle. Version 3, I took Zblj's suggestion and replaced the 20z's with knob gears. http://www.bricksafe.com/files/Tommy_styrvoky/differential%20xl%20V3.ldr

I reinforced the differential further, I don't think it will come apart or have any problems now. http://www.bricksafe.com/files/Tommy_styrvoky/differential%20xl%20V2.ldr

Images have been added.

I will try, as I am at school and for some odd reason I can't upload photos to flickr, but I can try uploading to bricksafe.

I have designed this reinforced differential for a large 2 differential steering system for a very large tank model in the far future. I lack the small turntables to build this at the moment, but I believe this will function correctly and be a medium sized differential that doesn't utilize the large turntables. Since I lack the small turntables, I think this will work, but I'm not sure how well it will hold up to torsional stress, but this could be fixed if there is 2 gears being used to power both turntables in sync. It may be prone to seperation where the turntables are connected to the main frame of the differential.

I saw a similar concept using lego treads to move a vehicle under a street, I wonder if it is possible to use old lego train magnets to perform the same action.

I thought those were lego parts.... Though I did see a tire that someone used that was stretched to fit like the gasket o-rings you have.

The power distribution schematic interesting, I can't wait to see this model finished.

Outstanding models, what rubber pieces did you use for the rear wheel on the tracked version?

pretty good job, I have made a motorized lego camera rail slider, and a smaller tripod for close up shots. The lego system provides a cheap means for producing mounts, the only problem is a lack of proper bearings between the rails, this leads to occasional small bumps where tiles meet.

I may find a use this concept and compact this gearbox in parallel, for a tank.

I forgot about a few photos, so here are some more of the model outside, I may decide to convert one of them to serpia, to make it look like the actual vehicle on the Russian front.

I had some fun in gimp and created some "blueprints" for the model. Lego Tiger Porsche blueprints (RC) by Tommy Styrvoky, on Flickr

Here's another photo, I think it's a scale issue, as I used the same reference points, front of mantlet, back of trunnion/lift point, and rear of turret. I had to slightly scale up your image, so i'm sorry if it's a little blurry, and the photo is a little too far back for the reference points, as I missed the back of the turret with the bustle/storage. tigers by Tommy Styrvoky, on Flickr

I think my model may be slightly smaller than yours, as the whole vehicle is 37 cm long, so the scale may be 1/19th, but I will try scaling a blueprint to the model like you did above. Well I have a small issue with perspective, as it is difficult to get a perfect photo of the vehicle from above because of the tripod, but It looks like the turret should be even a tad shorter, I think the difference between my turret and yours is the thickness of 1-2 plates. blueprint overlay by Tommy Styrvoky, on Flickr

Lego Tiger Porsche heavy tank (RC) by Tommy Styrvoky, on Flickr I present my first model as an AFOL, a Tiger porsche or Tiger (P). This vehicle, and the Tiger I (H) (the more commonly known Tiger tank) was built to meet the requirements of a 45 ton vehicle that could mount a 88mm flak inside a krupp turret. Durning the testing of the two vehicles, the Porsche version struggled with teething issues in the electronic drive motors that drive the rear sprockets. This vehicle has an interesting means of propulsion, there are 2 V10 engines that drive generators, that in turn provide power to the rear drive motors. This eliminates strain on a mechanical transmission, and allows for ease of "shifting" between different amounts of power supplied to the rear drive motors. Because of the issues with the over-engineered drivetrain, the vehicle lost the competition, and it was not put into production. There had been a total of 100 hulls built by Porsche, and only 5 Tiger (P)s were finished. This vehicle is one of the few that saw actual combat, the markings of it are from the Panzerjäger Abteilung 653rd. I got the inspiration for this model from Sariel's Tiger XL, and I decided it would be cool to utilize his turret (like the actual tiger (P) used the same Krupp turret). I have made a couple small changes to the turret, as it was slightly too long, and the sloped portion was too short. The hull of the tank is packed with motors and details, as I replicated the entire engine bay, and that alone takes up at least 1/3 of the entire vehicle. The rest is filled with the 5 motors inside of the model.
