CP5670 Posted October 19, 2015 Posted October 19, 2015 (edited) (click for more pictures) Video: A trial truck with all-wheel drive, steering and suspension. I was going for the size here and wanted to make the chassis small and compact, while still having differentials. The performance is decent for its size, good enough to play with although it struggles a bit on slopes. It uses two PF M motors for driving and a servo motor for steering.

2LegoOrNot2Lego... Posted October 19, 2015 Posted October 19, 2015 Nice build, nice concept, love the 4 wheel steering and the colors! Do you have any idea why it struggles on slopes? To me it seems like this Ranger should be capable of much more... Quote
CP5670 Posted October 19, 2015 Author Posted October 19, 2015 Thanks. It would definitely do better on slopes and rough terrain with L motors, but I used M motors to keep the size small (they just barely fit and L motors would need some adjustments to the rear area). Quote
Kman860 Posted October 20, 2015 Posted October 20, 2015 I didn't even realize it had motors until I read it did-which means you did an amazing job on hiding them and an amazing job on the model itself Quote
CP5670 Posted October 21, 2015 Author Posted October 21, 2015 Thank you. The motors are visible in this picture, where you can see that it's a tight fit. Quote
Rockbrick Posted October 22, 2015 Posted October 22, 2015 great size and it would go faster with less weight (lipo box) love the portal axle drive - so simple and using diffs too ,,,! how to you get it to crawl steer and normal steer with one servo? Quote
CP5670 Posted October 23, 2015 Author Posted October 23, 2015 It only does normal steering; the u-joints in the steering geartrain have a bit of slack so the wheels occasionally fall out of alignment. The LiPo box is a good idea, as the 9V box definitely adds a lot of weight to it. Does its lower voltage affect the PF motors' performance? Quote
