Like a Rolling Brick Posted January 22, 2017 Posted January 22, 2017 Hi guys, this is my first Lego Technic MOC so far. It's a truggy inspired by a real RC model, HPI Trophy Truggy Flux. I wanted to create a model that resembled as much as possibile a real RC truggy. The model is 100% Lego and it's 39 cm long and 25.5 cm wide. Its weight is 1.230 kg. It's powered by 2 RC Motors and a RC Unit, and it also features 4 independent suspended axles. The chassis is flat and the arms are parallel to the ground. The front steered axle comes with several mods from Sariel's great Trophy Truck. Unlike Sariel's model, however, the real axle insn't dragged but the arms are fully independent. The rear towers that support shock absorbers are wider than the front ones. Note that rear shock absorbers are mounted differently than the front ones because of the different design of the axles (the front ones have limitations due to the use of the part #15459 - Light Bluish Gray Technic, Steering Arm 5 x 1 with Towball Socket Rounded, Chamfered) I choosed to use the outer output of the RC motors, that in theory should give less speed but more torque on offroad tracks. The hubs mount 56mm D. x 34mm 3 pin holes wheels, so both 94.8 x 44 R Balloon Crawler's and 94.3 x 38 R Unimog's tyres fit the model perfectly. The chassis is completed by two oversized bumpers and a sturdy deck wing. As in a real RC model, the bodyshell can be completely removed from the chassis (in a Lego RC truggy this feature has no real meaning, because there are no electronics to have access to, but I always found this feature cool, so I kept it! ) For the bodysheel I took my inspiration from the new 42065 Tracked Racer. The white-and-red colors scheme is anyway the same of the HPI Trophy Truggy Flux. I choosed to leave the bodyshell rather crude, without adding many details, to make it light and simple as real RC models. This is also useful when driving outside, because it minimizes the risk of losing parts. I tested the truggy in my aparment and then outside on asphalt, cobblestone, dirt and low grass, and it performed not bad... for being a Lego model, I mean The best performance was on harder terrains, like asphalt or cobblestone. On the dirt the motors started to suffer due the lack of torque. The poorest run was on the grass, even if it was dry because of the winter cold. The lack of torque was particularly evident climbing little hills... the motors often stalled. On the straight, the peak speed was decent even if not amazing. ...Maybe in a couple of weeks I'll shoot a video of the truggy to show you its performances! Quote
BusterHaus Posted January 22, 2017 Posted January 22, 2017 I like this creation quite a bit, I hope you get to make the video because I would love to see it in action. Quote
schraubedrin Posted January 22, 2017 Posted January 22, 2017 Great model! It's instantly recognisable, for a short moment i believed to be on the wrong forum Quote
Leonardo da Bricki Posted January 22, 2017 Posted January 22, 2017 Cool model! Despite its simplicity, the bodywork looks good. Will you make a video? Quote
Albo Posted January 24, 2017 Posted January 24, 2017 Hi everybody and thanks for your appreciation! Glad that you liked the truck. I really would like to shoot a video of the model... but I'm pretty lazy and it may take a bit... We'll see! Quote
2LegoOrNot2Lego... Posted January 24, 2017 Posted January 24, 2017 This is an amazing build! Really nice application of the RC parts of which I still think it is to bad are no longer produced (or anything similar for all that matters) The looks are amazing and really looking forward to a full action video!!!

GBTechnic Posted January 29, 2017 Posted January 29, 2017 Love the build... another example of why I need to get some buggy motors! Quote
mocbuild101 Posted June 7, 2017 Posted June 7, 2017 I just had to bump this , it needs to be seen again! Great MOC, it looks exactly like a RC truggy! Nice work with the body too, the dual colours look great! Quote
kbalage Posted June 7, 2017 Posted June 7, 2017 Wow, I really like the design! Any chances for that video after these months? Quote
TechnicRCRacer Posted June 7, 2017 Posted June 7, 2017 (edited) Wow! That truggy looks so fun to drive! I really want to build this! Unfortunately, I do not have any available parts: building as many creations as I can for BBTB! Edited June 7, 2017 by TechnicRCRacer Quote

TechnicRCRacer Posted June 8, 2017 Posted June 8, 2017 @mocbuild101 What Milan said is exactly right! Quote
mocbuild101 Posted June 8, 2017 Posted June 8, 2017 It's probably because it's an American event that I didn't know, but now I do... Quote

TechnicRCRacer Posted June 8, 2017 Posted June 8, 2017 Hah, yeah. It is around San Francisco-ish. Back on topic, the spoiler looks amazing on the truggy! Quote
Aventador2004 Posted June 8, 2017 Posted June 8, 2017 (edited) Awesome truggy! I need buggy motors! Edited June 8, 2017 by Aventador2004 Quote
TechnicRCRacer Posted June 9, 2017 Posted June 9, 2017 (edited) @Like a Rolling BrickInstructions, please? I want to build this so bad! I will find a way! Edited June 9, 2017 by TechnicRCRacer Quote
Like a Rolling Brick Posted August 20, 2017 Author Posted August 20, 2017 (edited) Hi guys! After sooooo many months I decided to disassemble the truggy. I took some pictures to create the building instructions... unfortunately I did it with my smartphone, so some of them are blurry. Anyway they shoud be useful if someone wants to replicate the model with his own parts. Enjoy! Flickr album Edited August 20, 2017 by Like a Rolling Brick Quote
Leonardo da Bricki Posted August 20, 2017 Posted August 20, 2017 Thank you so much!!!! I cannot wait to try this out! With some mods... Quote
