Teo LEGO Technic Posted February 28, 2015 Posted February 28, 2015 Hello everybody. My next MOC is a mini T815 with 8 x 8 drive powered by 2 x L. The model was built to climb the maximum possible slope, while looking good and having high ground clearance. Therefore, the cabin is very heavy too, and all weight very low to stop it from falling over. It also enough torque so as never to run out. Suspension is half-axles, tatra style. A video showing all the features: Another title photo And showing the mechanics: I hope you all like it! Quote
Coola1 Posted February 28, 2015 Posted February 28, 2015 Awesome build, great offroad performance and speed! Quote
Teo LEGO Technic Posted February 28, 2015 Author Posted February 28, 2015 Awesome build, great offroad performance and speed! Thanks! originally I wanted it to be very fast, to minimize the trouble with too much torque. Then I decided to make it be good at slopes, so I geared down the L's a lot. Quote
sama Posted February 28, 2015 Posted February 28, 2015 (edited) Nice model. This thing has alot of torque. What gearing did you use (what is the gear ratio)? Also, which battery box did you use? Edited March 3, 2015 by sama Quote
HorcikDesigns Posted February 28, 2015 Posted February 28, 2015 The only thing I do not like on it is the red smallest panel (I do not remember it's dimensions) filling the side of the cabin. But everything other on this truck is awesome. And, it reminds me Madoca's T813. I can't deciede whether it is good or bad. It is just fact. ;) Quote

What hearing did you use (what is the gear ratio)? Also, which battery box did you use? I used a rechargeable battery box, tucked in at the back of the cabin, and gearing 2:1 for each L. Quote
Teo LEGO Technic Posted February 28, 2015 Author Posted February 28, 2015 nice moc looks super fast Thanks! Quote
Rishab N Posted February 28, 2015 Posted February 28, 2015 Great Tatra and I love how it's in such a small scale Quote
Teo LEGO Technic Posted February 28, 2015 Author Posted February 28, 2015 Great Tatra and I love how it's in such a small scale I did try to keep it as small as possible, because heavier models need more torque than lego can take. Quote
750ACE Posted February 28, 2015 Posted February 28, 2015 I like the fact that the axles are in line with each other however I am not familiar with true Tata wheel alignment. Looks awesome at a great small scale! Quote
Teo LEGO Technic Posted February 28, 2015 Author Posted February 28, 2015 I like the fact that the axles are in line with each other however I am not familiar with true Tata wheel alignment. Looks awesome at a great small scale! In real life, the axles are all driven by a single central drive shaft, and are in line with each other. I used two drive shafts to allow skid steering. Quote
KirTech LAB Posted February 28, 2015 Posted February 28, 2015 Very good performance! Maybe I missed it - what is its weight? Quote
Kelkschiz Posted February 28, 2015 Posted February 28, 2015 Great little Tatra, like the minimalistic approach, very nice performance as well! Quote
Teo LEGO Technic Posted February 28, 2015 Author Posted February 28, 2015 Great little Tatra, like the minimalistic approach, very nice performance as well! After my big last MOC with a lot of torque, I wanted something small and effective. Quote
VKTechnic Posted February 28, 2015 Posted February 28, 2015 The suspension reminds me of ZBLJ's mini trial trucks from a few years ago: Quote
Zerobricks Posted February 28, 2015 Posted February 28, 2015 The suspension reminds me of ZBLJ's mini trial trucks from a few years ago: Just wanted to say that How did you make suspension? Quote
Teo LEGO Technic Posted February 28, 2015 Author Posted February 28, 2015 (edited) Just wanted to say that How did you make suspension? You're MOC was used as a baseline. I wanted to make a more powerful version. But the chassis is really similar otherwise. The suspension is made for side to side, not up and down, to handle terrain, not comfort. Here's a picture: DSC01100 by teo_technic, on Flickr It uses rubber bands and rubber 1x2's. Edited February 28, 2015 by Teo LEGO Technic Quote
Zerobricks Posted March 1, 2015 Posted March 1, 2015 So its simillar suspension as my version? I'd like to yours in more detail. Quote
Teo LEGO Technic Posted March 2, 2015 Author Posted March 2, 2015 So its simillar suspension as my version? I'd like to yours in more detail. Yes, the suspension is similar, except for the front-most which uses rubber bands in a way that allows up and down, and side to side motion, so that the truck does not flip when it hits an object at high speed.

Rockbrick Posted March 2, 2015 Posted March 2, 2015 Impressive speed and climb! shame its only skid steer - but tat this scale and in the dirt that is probably an advantage! Quote
Teo LEGO Technic Posted March 8, 2015 Author Posted March 8, 2015 Impressive speed and climb! shame its only skid steer - but tat this scale and in the dirt that is probably an advantage! Thanks! It's true, skid steer is not as cool, but I was doing everything to keep it small and powerful to climb the 70 degree slope! Quote

What is skid steer? Also, ZLBJ, do you have an LXF of your version? So it could be converted to this guy's MOC? Quote
Teo LEGO Technic Posted March 8, 2015 Author Posted March 8, 2015 What is skid steer? Also, ZLBJ, do you have an LXF of your version? So it could be converted to this guy's MOC? I used ZBLJ's idea for the suspension, but the chassis and body are original. Also skid steer is where either side of a car are separately powered to steer when turned in opposite directions, like a tank. Quote

I can start it, if anyone wants to help, I could finish it in way less time. I'm starting off with ZBLJ's LXF. I'll change the body later. https://drive.google.com/file/d/0B7ClftNJdh9_REdTcUs4T0M1NHM/view?usp=sharing Quote
