Blue Rock Crawler

[Tamas Juhasz]

I present my latest crawler:

It's main concept is similar to my previous crawlers: nothing unnecessary part and weigth, as simple and reliable technik, as it can be. The chassis is enoug flexible to do this: http://www.brickshel...Crawler/021.jpg - so you don't need more advanced suspension in this concept. Two XL motor drive, one M motor steers the vehicle. For power supply there is one LiPo battery and a V2 receiver built in.

The front part is heavier, thanks to the small wheels in the front rims and the ship weight. The chain holds the weight in position.

This crawler also has the usual rock crusher tires, in my case, from RC4WD.

The body is partly from the 8437 official model:

I lookde around my room in the beggining of body building time, and the 8437's body in my showcase just gave himself to connect

with the chassis. I wanted to make a tubular body/frame.

Has a fake L6 motor in the back too:

As video, there is the first part (from 00:40 to 20:55) of this video:

(720p)

This was an RC track test, for more information see this topic:

Looks and drives very well, I love the fake engine. The only thing I dont really like the is the position of the front motor...I think you can put it into a simillar position as the rear one with a few tweaks.

[Tamas Juhasz]

Thanks. Yes, I also thought about alternative positions, but because of simplicity, this was the best. I used a strong part for holding together the bevel gears, it needs quite a lot of space:

And this allows to use the thick 12 tooth bevel gear, so it won't break if you put it to the XL motor's axle, like the thin 12 tooth one.

"...nothing unnecessary part and weigth..."

I love this statement, followed by:

"Has a fake L6 motor in the back too:"

I would love to be able to go to a trial track, unfortunately there aren't that many around me:(
