I have designed a Technic trial truck. It has 4wd and is remote controlled. It has two L-motor's for driving, one in rear, one in front. It has a working V8 motor. It has steering in the middle, just like a wheel loader. Of course it has a remote controller, but it is not on the photo.
I design this for fun, but getting a real model would also be nice
I think this can be good for lego because I think many AFOL's would buy this one and it is nice when both young and grown up can buy lego models they like.
