[WIP] Red Coupe RC
Daniel-99 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello everyone, today I`m going to reveal to all of you my Red coupe MOC that I placed on my avatar ;-) A long long story begins There is a long story of development of this car. It starts with my childhood dream and the First Lego technic PF car (see https://www.eurobricks.com/forum/index.php?/forums/topic/188301-fitst-pf-technic-car-moc/&tab=comments#comment-3468455 ) (that I built in 2012). After I left my hobby for about 4-5 years. And then I returned with RC MOD of Chevrolet Corvette set (see https://www.eurobricks.com/forum/index.php?/forums/topic/188300-chevrolet-corvette-42093-rc-mod/&tab=comments#comment-3468619 ). After that I tried to deal with a big scale (1:10) by building an RC MOC of Porsche 911 RSR (see https://www.eurobricks.com/forum/index.php?/forums/topic/188322-porsche-911-rsr-rc-moc/&tab=comments#comment-3469094 ) - that was a big challenge for me and required a significant upgrade of my lego workshop... At the very end of my story with Porsche, I get some ideas for a new car... but to build a car from that ideas took me 2 more months. The cassis and first ideas of the body I was developing a new RC chassis for my Porsche 911, it is a long process, you know... Finally, the chassis has been developed. It was built out of ideas and I was very pleased with it! I needed to add several mounting points to it in order to swap the body. The chassis was waiting for me on the next desk where I used to play lego and I was doing my everyday job on computer. Then suddenly, I looked up onto a shelf and noticed, that fenders from Land Rover set 42110 has a nice shape as a front grill! I checked my idea, and it worked! At that moment I realized that the story of a new car begins!... To build the back lights of the new car I use the old Bionicle heads! And made first lines of the roof and A-pillars After that the process stopped... New fenders from Ferrari set Process stopped... I was struggling a low with making the wheel arched for front wheels... the bonnet I made required me to make a very sport-like very slime and curved wheel arches. At the same time they needed to be sturdy enough for outdoor driving and also provide some space for the suspension travel... After a month of unsuccessful attempts I was ready to give up! But likely for me, the new Lego set Ferrari 42125 has arrived! I waited for another month for a "good" price since it was totally overpriced form the very beginning. The Ferrari fenders bring the new power to me. Also they provided the color for the car. To finish the bodywork in red I bought two Ducati sets their parts help me a lot! On the photo you can see the gorgeous moment of attachment of the side-panels to the car. After I solved the problem with fenders, the car was assembled piece by piece in such a way, that all my ideas nearly "provide" the form of the car and the part use. As you can see, the first prototype of a bonnet was lifted up to be a roof ;-). Some underlying ideas for bodywork: - Short front and back bumpers (comparing to the Porsche set) - Front grill with a fender from the Land Rover set - Narrowing door panels The car has no interior and no doors, since I was building an RC car. I was saving the weight. Final car with batteries (Buwizz) has a total weight of 1,5 kg. Photos of a finished car Hope you like it! After finishing the first version, I made a significant update of it. Now it is equipped with 2 powerful Buwizz motors and powered by 2 Buwizz 3.0 bricks. The total weight is 1,63 kg and the mass of the car is moved closer to the rear wheels for a better grip. All electronics is located in the lowest 5 studs of a car so it is very stable and quite fast (about 12 km/h) it is really fun to play. But you heed a flat areas since the ground clearance is about 2 studs (all in all it is a sport car). The suspension is independent and very responsive. I have no video to share for now and the winter has already come, so I will wait until spring! Now im 100% involved in 4x4 technic RC off-roaders.... P.S. I will try to make a OPDF instruction for my MOC, but it will take a lot of times. And if you have any questions, no not hesitate to ask me - the car was not disassembled and it is waiting for the warn and sunny days on a shelf ;-) -
Porsche 911 RSR [RC MOC]
Daniel-99 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello everyone! Im very glad to show my RC Porsche 911 RSR. As always, story begins far far in the past... My childhood dream was to get an RC car... Some time ago I shared with you a Corvette RC mod, and that was the "first step" in my dream coming true! In that project I understood, that a lego car can go a decent speed especially with the Buwizz 2.0. BUT... But the speed uncovered a another problem, that is the lack of control! Lego bricks have too much wobbling... Searching for the solution of this problem in the internet I found several buggy projects with technic bricks that has a positive caster... Ant I instantly understood that the positive caster is the thing I need in my car. Also, I was struggling a lot with gigantic scrab-radius. But in that time all rims produced by lego was symmetric. Finally, the Land-rover set has arrived... And the new rims give me some hope... Now I was going to build a 1:10 scale car. But the Land-rover set itself was a bad candidate for motorization due to it`s mass and a wobbly chassis. Due to the lack of skills in bodywork I decided to modify the lego set. I choose a Porsche 911 RSR set for my needs. One would ask me: why you call this RC mod a MOC? Well, the cassis of lego sets are totally inappropriate for making RC cars - most of them are too wobbly and weak. Moreover I wanted to build a positive caster. So I decided to build a custom RC chassis that will for to the bodywork of the initial lego set. Here is a front suspension. Yeah, that is my first "finished" chassis with suspension. Do you see some unusual ideas? I managed to build a double steering arms in order to make the steering system stronger. Moreover, I made a double steering rack steered with a single gear... On the back I decoded to build a live axle with motors connected directly to wheels: no friction on gears, no weak universal joins... I used the original instructions to check the dimensions! Here you can see the finished chassis - nothing special! I placed several smaller wheels for comparison. I would like to mention, that my first RC car was build with the smallest wheels (the very right wheel on the photo). The main reason why I build a car with small wheels was the lack of power the lego motors have (as I thought back then I was at the very beginning of my lego technic build experience). The main question for now: will the motors have enough power to move this big chassis? I made the first drive, and the car really goes well! Unfortunately I did not make a video, but it was going about 7-8 km/h - that was not a bad speed comparing to the 9398. After finishing the chassis I started the bodywork. Then I build front and back parts of the body (with a lot of changes from the original) I decided that it would be great to have a single body-unit that sits on the chassis on several attachment points. And this is the result: The main reason why I build a detachable body is because I was going to make modifications of chassis! Hope you like my post and the car ;-) Feel free to comment on technical aspects. P.S. one fan fact about this car: this RC car has only one gear! - sounds crazy, isn`t it,
