N1K0L4

I've built quite a few of these lately, so I wanted to share it with others and say something about each one. I hope you'll find some of these useful. :) 1. Keyholder: This one I built quite a while ago. It's pretty durable and you can spin the keys around. https://rebrickable.com/mocs/MOC-171645/N1K0L4/lego-keyholder/ 2. Camera stick with stabilization I built this at first to help me shoot my RC creations while driving them, but I can use it as a hand-held one too. https://rebrickable.com/mocs/MOC-186202/N1K0L4/camera-stick-with-stabilization/ 3. Motorized personal cooling fan: This one I built recently because of hot temperatures during summer. It has over 30 min of run time on full throttle. https://rebrickable.com/mocs/MOC-179802/N1K0L4/motorized-personal-cooling-fan/ 4. Hand-powered personal cooling fan: The previous fan was a bit too loud for some places (mainly in public), that's why I built this one. It uses 1:9 gear ratio and also has 2 handle positions. https://rebrickable.com/mocs/MOC-187501/N1K0L4/hand-powered-personal-cooling-fan/ I showed them all in my video: Feel free to share ones you built.

Awesome, I like it more than the original set.

I could, but then it wouldn't have enough power for drifting because of 4WD. It should be able to drift quite nicely with some tape on the tires or on some slippery surface.

So, here's the first update: After some iterations, this is the driveline I came up with. Geared down 1.25:1 from the fast output of the BuWizz motors it'll be some 15% slower then the RWD version, but with more torque. I also improved the looks and stiffness of the body. Now I just need to connect everything into one.

I started mine at 13 also, so you're not alone :)

Nice build! Great to see some more detailed information about a model. So about that freewheeling, doesn't the driveline create a lot of friction causing it to brake a lot?

Good idea, I especially like the body with it's organic shape. Great job with that! Have you had other versions of that wheel before this one? Also, I'm Nikola from last year's BuWizz camp. It was nice meeting you there and I hope I'll see you this year too. Anyways, I wanted to say something. If size really matters, how did I then manage to not be near last place in the offroad competition ob BuWizz camp with my Mini Tracked Vehicle ( https://rebrickable.com/mocs/MOC-165686/N1K0L4/mini-tracked-vehicle/ )? I was at least 3 times smaller then everyone! Have a great day ;)

Yes I have, and I still do.

Hello everyone, I would like to tell you a little story of my 2 MOCs I built and how they evolved through number of other models in the last year. i hope you'll like it Note: after the GO-Kart MOD every model has the same motor and battery layout. It all started in February 2023. when I decided to motorize my 42048 Go-Kart with BuWizz 3.0 and PF L motors. I did it by placing 1 PF L motor for each rear wheel and also making a high angle (60°) steering system so it had a very good turning circle with top speed of 5 km/h. Then at the end of April 2023. I decided to build something faster. The result was the Green Formula V1, which had the same steering as the Go-Kart, but was powered by 1 BW motor. It had replaceable rear axle with easily changeable gear ratios. The car preferred understeer, which wasn't perfect, but it could still turn quite hard. With a 1:1.66 gear ratio I managed to get a top speed of 23 km/h. I had that model assembled for quite a while, full 5 months without any major upgrades. I really drove it everywhere, on school trips, camps, vacations, in the middle of a hot summer day and at night in the parking lots. After the success of that model, I got an idea of a compact front suspension and I decided to build it into the formula. It worked very good, but it lacked the rear suspension, so then I added that too. It preformed good, but it just wasn't right, it had too low ground clearance and the formula bodywork was getting damaged by light offroad terrain. That's the point when this model evolves into 2 different models. First one being a remake of it with a buggy body. Wheelbase is 2 studs shorter and it has more ground clearance due to bigger wheels. I also managed to build the chassis much stiffer compared to the formula. It drives very well and it also favors understeer. With 1:1 gear ratio top speed is 18 km/h. I also made 2 YT videos showcasing the model: The second model is a smaller remake of the original formula without suspension. It has 2 studs narrower and 5 studs shorter wheelbase with much more responsive steering and slight better looks. With a 1:1.66 gear ratio I managed to get a top speed of 23 km/h. It also has near perfect weight distribution which gives it awesome handling. It is sooo enjoyable driving it on tarmac on the limit. If you steer too much into a corner it will slowly make the rear slide, no snap oversteer or understeer. For me, this is the best handling car I built. This also might be my model to compete in Mini Racers class at BuWizz camp, if I don't build something better (I'm working on it ). I also made a video showcasing it: I hope you liked this little story/recap/history of these models. Feel free to post a comment about your thoughts on this. I hope you'll have a great day
