Toni-23 Posted June 27, 2017 (edited) hi everebody! Today i would like to show you my new 4x4 pickup truck. Specifications: dependent suspension portal axles 2 buggy motors for drive(geared 13,8 :1) 1 M motor for steering 107 mm wheels so,here it is and the video available here: Edited June 27, 2017 by Toni-23 Share this post Link to post Share on other sites

technic_addict Posted June 27, 2017 Typically people use L or XL motors for vehicles like this so it is interesting the use of two buggy motors. What gearing did you use to improve the torque of the buggy motors? Share this post Link to post Share on other sites
grum64 Posted June 27, 2017 I'm liking this a lot, it has a sense of purpose to it. Performance seems pretty good. Share this post Link to post Share on other sites

What gearing did you use to improve the torque of the buggy motors? gear ratio is 13,8:1(low speed output) i think it's enough for this truck:) 23 minutes ago, grum64 said: I'm liking this a lot, it has a sense of purpose to it.

Splat Posted June 28, 2017 It seems to run very smoothly over most terrain. What is the purpose of the large linear actuators at the front? Are they part of the steering, or used as variable length linkages for the suspension, or something else? Share this post Link to post Share on other sites
1gor Posted June 28, 2017 It looks cool, but depending on size it could be called Monster 4 x 4 offroad pickup Share this post Link to post Share on other sites

I think about that.But only with power puller wheels it can be looks like monster truck,because they wider,than wheels from 42054 Share this post Link to post Share on other sites

About Powepullers you are right, so called BigFoot pickup like in U.S. shows is kind of monster 4 X 4 and PP wheels would be perfect in that case...

Lakop Posted June 28, 2017 Nice. Good video, it performs well. H Share this post Link to post Share on other sites
LEGO Train 12 Volts Posted June 28, 2017 Amazing pick-up and impressive suspensions system! Share this post Link to post Share on other sites
TechnicRCRacer Posted June 28, 2017 Interesting! Typically, I don't like monster/pickups because they are so slow, but you did a great job of making it fast! Share this post Link to post Share on other sites
nerdsforprez Posted June 29, 2017 Funny.... I am actually working on a similar, but certainly not the same, project. When 42054 came out with the new wheels, I instantly thought of a.... what is called a "redneck" mudder here in the US. LIke this.... And knew that I had to build one. Been side-tracked with so many other projects and work.... haven't had a chance to finish but hopefully will soon. Mine will be powered by hopefully two XL motors..... perhaps will be slow but I actually hope to film it doing what I want it to..... go through some gnarly muddy conditions..... Yours is a fun little project. I must say that using the actuators is different for links......did you also consider the 1x16 links? They typically work very well for these applications.

Leonardo da Bricki Posted June 29, 2017 Great balance between performance and speed here! I like the simplicity of the design, its very clean and looks good! Share this post Link to post Share on other sites
PorkyMonster Posted June 29, 2017 Only playable off-roader I've seen... the rest using PF motors are too sloooooooow... alternative to buggy motors will have to be 3rd party motors for such models to be lively. Share this post Link to post Share on other sites

They typically work very well for these applications. So,it is good idea But as for me 1x16 links are too flexible and elastic and axles can move left-right on high stress.Thats why i use large lineal actuators and beams like linkages. behind little .Thanks to a slight backlash of gray pins, the suspension works well. 9 hours ago, PorkyMonster said: alternative to buggy motors will have to be 3rd party motors for such models to be lively. One day i used 3rd party motors(more powerful than baggy motor a little bit) in MOC,but lego receiver cant provide enough current for the motor and,i think, lego plastic is not designed for such loads:( Share this post Link to post Share on other sites
