Lego Technic RC Buggy Car

[knightrider1545]

Are you going to put a rc nitro engine in it?

[SuicideChicken100]

i would let my rc tank ride over that lmao

[sportworksrc]

were do you get this stuff

[alexproductions13]

I'm sorry, but is there anyway for instructions?!

[jason160uk]

@alexproductions13 lol Well not anytime soon im afraid, but thanks for asking :)

[alexproductions13]

@jason160uk haha ok, and if you changed the gear ratio a bit you could get enough torque for it to be able to go offroad

[kind18cch]

try adding a LSD, otherwise it will get stuck when offroad

[jason160uk]

@kind18cch LSD? your talking to a technic guy here lol

[kind18cch]

@jason160uk you just need some rubber band. search for "LEGO Technic Custom Flat-bed Truck - LSD Operation" in youtube, it explains lsd pretty well

[Tyralash]

@jason160uk Limited slip differential?

[chadro85]

have you tryed it on anything outside ?

[jason160uk]

@chadro85 Well no, if it had more torque I would.

[LittleGreenLEGOMen0]

How come your using hard springs, is it because of the weight of the model? off road vehicles usually have soft suspension

[jason160uk]

@LittleGreenLEGOMen0 Well I used the suspension that came with the 8297 set which are designed for the weight of the vehicle. By altering the height and angle of the suspension in relation to the wheel I could weaken or strengthen it, but I couldnt weaken it anymore as if I did the car would not bounce back up again due to the weight.

[chadro85]

@LittleGreenLEGOMen0 yes usually off road vehicles have soft suspension. but there is a company called "Teraflex" that makes jeeping parts mostly suspention. much of their suspention parts are much harder then normal jeeping suspention. but they seem to work alot better than soft suspention. i'm friends with a guy who works there. i've ridden in jeeps with stock suspention and his jeep that is all teraflex. they drive much smoother on bumps then normal stock jeeps

[LittleGreenLEGOMen0]

@chadro85 hmm, does he use his jeep off or on road?

[chadro85]

@LittleGreenLEGOMen0 mostly off road. but on road to when needed. (like when driving to where ever were offroading at) i can p.m you with some of their videos of jeeping. if you would like.

[MonkeySmist2]

8297 is one of the best Technic sets ever released!

So many awesome parts!

[jason160uk]

@MonkeySmist2 Well said, was my first ever set from the new modern technic so to me it was like being a kid again lol I love technic :)

[RCCFanatic]

Now you should put a 540 to the rear wheels that will get it going

[jason160uk]

@RCCFanatic a 540? Id like to know what that is, im guessing its nothing from Lego :)

[RCCFanatic]

@jason160uk It is nothing from lego its a standard 1/10 scale rc motor brushed and brushless. They run from 7.2v to 11.1v mostly 7.2v They are used in rockcrawlers and moster trucks they run at a very wide veriety of wids(determens speed lower winds faster higher slower) The 540 motors i have all run over 23,000rpm they have a pretty high torque but you can stop them by hand (HURTS) they can wear out by improper care they also are bigger and smaller there are 380 540 550 600 just to name a few.

[jason160uk]

@RCCFanatic Sorry for the very late response, I just wonder have you tried these motors with technic? Is it compatible and would it not just damage the technic cogs and the like.

[EthanX817]

@jason160uk 540 motor and yeah nothing from lego

[TheNephew31]

@jason160uk its a eletric motor

[zzefizz]

what does the remote look like?



[jason160uk]

@zzefizz The remote is the standard lego technic remote you get with all their models, I havent done anything fancy with it as it works just fine :)

[Nateisback76]

great truck but the stance is kinda wide. otherwise nice truck 5 *

[jason160uk]

@ElektronikFan Thanks very much for the comment, I appreciate it :)

[DanielBLOG2]

use bigger motors

[jason160uk]

@DanielBLOG2 Have you read the comments, you think I havent tried.... that was the first thing i did try but they kept slipping and tearing at the gears.

[killersushi99]

Lego. Wow. Time to move on to something with some speed.

[thelizard50]

i' ve got a question. do you use a differential for the steering, too?

[jason160uk]

@thelizard50 Hello, no differential on the steering, I used a number of cogs going from small to large to slow it down.

[thelizard50]

@jason160uk

ok thanks for your response. but do you know how to make a differential on the steering?

[jason160uk]

@thelizard50 I have to say I have never heard of using differential for steering, only for the back wheels, so no i dont know, im quite the amatuer when it comes to this, this is my first ever remote controlled technic car, whats the benefit of using differential for steering?

[thelizard50]

@jason160uk

well, the benefit is that steering is more precise, so you get less slip. but i think the only problem is that my steering is too weak. i need a more solid steering construction. your steering construction seems to be quite good. do you have maybe a construction manual for me ? :D what construction kit of lego did you use for your car ?( there are some some parts i' ve never seen^^)

[jason160uk]

@thelizard50 Now your asking haha, it would be great if I did have a construction manual. I dont get any slip from the steering I created on this model, when using the black plastic rods for the cogs, you just have to keep every section of it tied down otherwise they slip like crazy, take a close look at the images in my video, they show close up the steering construction. The kit I used was from the 8297 off roader. Are you using old technic? This set is from the newer style.

[thelizard50]

@jason160uk

yes i'm using old thechnic. thats the problem i couldn't tie it down very good... so that may get me some trouble^^but anyway thank's for the response. i'll take a closer look... maybe i manage to make it better :D

[Marsteintoppen]

nice car :-)

[jason160uk]

Hi there, thanks for info. One of the reasons i got the 4x4 off roader was the information I found online about making it move with motors, using a large motor on the differential, I just couldnt get it to work, the gears kept slipping, but I think that just put me off the differential alltogether because not once did it occur to me about trying it on the medium motors !!

[Dr904]

Use a differential or u will burn your motors, and it will go alot smother.

[redgoldtomato9]

@Dr904 it wont burn the motors. io never use diffs.

[minifrog11]

it very cool but drive it out side

[SuperAiden101]

coool

[jason160uk]

Hello, well not all that fast, runs better on a hard surface, the kitchen footage shows it as fast as it will go.

I tried changing the gear ratio to make it faster but there was not enough torque to push it, its quite a big car you see, but i was impressed how well the two medium motors pushed it, i have never managed to get a xl motor working due to it tearing away at the gears.

[showfox24]

lol nice man, how fast can it go?
