Tommy Styrvoky Posted November 12, 2014 Posted November 12, 2014 I sort of stumbled across the idea of building an armored car. It happened when I was browsing through some of the 1/35 models at a hobby store, I saw a few British variants of armored cars. Following that day one foot of snow fell. I then researched some armored cars, a new sort of a project for me. As a am usually used to building tracked vehicles, having little experience with 4x4 vehicles ( this is my first 4x4). This vehcle is sort of a hybrid between a crawler and a tank. It will have a durable chassis with a 2 speed transmission powered by 2 XL motors. I would say that the gear ratios will be around a 3:1 for the low gear and 1:1 for high. With the current axle that I have built, it has portal hubs that add an additional 3:1 ratio to the driveline. the real vehicle blueprints scaled with Sariel's blueprint scaler.

MajklSpajkl Posted November 12, 2014 Posted November 12, 2014 Good choice, I am looking forward to your progress, I hopevthe snow holds up until you finis it, it would be so cool seeing it on snow and see how your snow chain concept works. Quote
Tommy Styrvoky Posted November 13, 2014 Author Posted November 13, 2014 more progress, the rear axle is complete and I have begun working on the transmission and steering assemblies. Lego AEC MK. III Armored car (RC) by Tommy Styrvoky, on Flickr Quote
VKTechnic Posted November 13, 2014 Posted November 13, 2014 Looking good Although that caster angle on the front axle will make handling a bit weird Quote
Tommy Styrvoky Posted November 13, 2014 Author Posted November 13, 2014 (edited) Looking good Although that caster angle on the front axle will make handling a bit weird it lacks the springs so the caster angle will be closer to perpendicular with the ground, the whole model is propped up by a XL motor.

VKTechnic Posted November 13, 2014 Posted November 13, 2014 it lacks the springs so the caster angle will be closer to perpendicular with the ground, the whole model is propped up by a XL motor. Ah, okay. It seemed to me that the XL motor was there to simulate the final ride height. Quote
Tommy Styrvoky Posted November 13, 2014 Author Posted November 13, 2014 Ah, okay. It seemed to me that the XL motor was there to simulate the final ride height. That would be way too high for the vehicle, It would have problems with mounting plates for the front and the sides. Quote
Tommy Styrvoky Posted November 14, 2014 Author Posted November 14, 2014 Lego AEC MK III Armored car (RC) by Tommy Styrvoky, on Flickr Transmission was added to the model, with a 12:1 in low gear and 4:1 in high gear (portal axle reductions included). Rear suspension was added, the steering motor was mounted with steering box on the rack and pinion. Though the motor may be moved to lower the area near the axles for the fenders. Quote
VKTechnic Posted November 14, 2014 Posted November 14, 2014 You're making short work of this, keep it up! Quote
Tommy Styrvoky Posted November 14, 2014 Author Posted November 14, 2014 You're making short work of this, keep it up! It should be short work, until I start working on the body, that may cause me to have to redesign parts to fit the proper shape of the body. I'm just trying to make the chassis as low profile as possible and hopefully I will find a way to cover up those XL motors. For protection when I drive it in the snow. Quote

Heres a short video of the vehicle crawling over some boxes. https://flic.kr/p/p95obg Quote
Tommy Styrvoky Posted November 22, 2014 Author Posted November 22, 2014 Lego AEC MK. III armored car (RC) by Tommy Styrvoky, on Flickr I finally have some more progress after this past week, I had several tests in classes and a 4000 word paper to type. The frontal shocks were removed and remounted and fenders were added. I'm not exactly sure how I will be mounting the battery box though I'm thinking under the turret. Quote
Scorpion Posted November 22, 2014 Posted November 22, 2014 Someone has Bradford's British AFV plans... Keep up the good work! ;) Quote
Tommy Styrvoky Posted November 22, 2014 Author Posted November 22, 2014 Lego AEC MK. III Armored car (RC) by Tommy Styrvoky, on Flickr Some work on the body, there was some minor changes to the steering mechanism to make it fit into the sides of the vehicle,more clearance was added to the frontal suspension, so it has a greater travel. Next part to be added will be the turret ring and turret, Lego AEC MK. III Armored car (RC) by Tommy Styrvoky, on Flickr Quote
Rockbrick Posted November 25, 2014 Posted November 25, 2014 coming along nicely indeed - unimog tyres would make it look more like the original Quote

Rockbrick Posted November 25, 2014 Posted November 25, 2014 If only I owned some unimog tires ... Buy the volvo set! Quote
Tommy Styrvoky Posted November 25, 2014 Author Posted November 25, 2014 Buy the volvo set! I don't have the money for that and I plan to finish this model up sometime next week, then I will be building another tank before christmas... Quote

Tommy Styrvoky Posted November 27, 2014 Author Posted November 27, 2014 (edited) I thought I may post a small update during Thanksgiving, I have begun shaping the frontal armor around the drivers hatch.

Tommy Styrvoky Posted November 28, 2014 Author Posted November 28, 2014 Lego AEC MK. III Armored car (RC) by Tommy Styrvoky, on Flickr I added the complex sidewalls of the vehicle, they are slightly too large, but the whole vehicle is too wide because of the internal components.

Rishab N Posted November 29, 2014 Posted November 29, 2014 Looks good. I like the angles you made on the sides Quote
DrJB Posted November 29, 2014 Posted November 29, 2014 (edited) Looks like you have a large collection of StarWars sets (LBG color) ... either that or you're depleting bricklink's supply of grey parts :) Nonetheless, looks very nice. I like especially your use of plates, as I'm not a fan of protruding 'studs'. Edited November 29, 2014 by DrJB Quote

I like especially your use of plates, as I'm not a fan of protruding 'studs'. I "had" quite a few Star Wars sets, but they eventually turned into my armored vehicles.I did purchase quite a few hundred grey tiles off of Bricklink. Here's an example of one of my first models, without many tiles. Quote
