Hi everyone!

I am very glad to introduce to you my modification of brilliant ACT truck made by Lucio Switch!

Truck 1_1 by Alexey Tikhvinsky, on Flickr

The heart of this giant are: 2 SBricks, 2 LiPo batteries, 4 buggy motors, 2 servos, 2 LED lights.

Later I will publish additional technical details and some internals.

Here is some outdoor photos:

Looks so good with the white-blue color scheme and 3rd party tires.

I was impressed with the performance, how fast did the 4 buggy motors drain the batteries?

Thank you!

Driving time is about 10-15 minutes.

Wow! I thought the first picture was the original and the following pictures the Lego version. Looking closely I noticed the lego parts. :-)

Very cool truck! Size is impressive, performance as well, details are very good and photography is great. Please share the underside shot, it would mean a lot to us :)

Brutal MOD :) Looks awesome in real life!

Wow. That's very impressive! Well done!

Thank you very much, guys!

That is sure a beauty! Can you share a bit more details on the construction/features?

I will upload pictures of the internals and some different modules later.

At the last photo you can see that the entire structure is modular. The motors are mounted from the bottom, between the back and front parts, you can see black-red-grey module in the center of the photo.

Was that a lizard at the very beginning of the video?

Yes, it is :laugh:

huge and powerful heavy truck, cool!

This is an excellent build! Cool you used someone else's design and took it your own way... Brilliant, it performs excellently well...!!! :thumbup: :thumbup: :thumbup:

I saw this beast in the beginning of the movie of topic [MOD] Dodge T-Rex 6x6 Friends Edition and was wondering if it ever showed up in a seperate topic. And here it is.... mighty, excellent build. :thumbup:

Thank you very much for your feedback guys!

I've already said that I like it, but I'm really impressed by the performance!! Really a good job!

Your MOCs are always a source of inspiration for me, I am very glad that you like the result!

Any update on the gearing on this beast? I'm curious. So slow (appropriately so...i.e. Not a bad thing) on buggy motors I bet the gearing is something crazy.

All that I have at the moment - this picture from Sariel's calculator:

_zpsk9go52vh.jpg

The only adjustment - in-wheel-reductor gear ratio is 4:1, not 3:1

So we have about 530 N*cm torque in total.

For example, Madoca's 8x8 Tatra has 725 N*cm and weighs more than twice less

thanks. I had the feeling that it was something quite extreme.

This really is a great model. and btw... the first pic, with the light coming through the tires, :wub: :wub: IMO one of the best pics of a technic MOC I have seen out there.....

Very clever design, even though it is based on someone else's design, you really did a great job!!! Love the limited slip diffs you used! :thumbup:

Limited slip diffs were invented by efferman, I used his axle design as basic structure.
