I'm designing an RC technic car (C8 Corvette) in Stud.io that I want to race against some other people. How many L-motors will I need to get the car up to a reasonable speed? (I'd like it to go around 5-10 mph, basically anything faster than a slow crawl). I have 2 L-motors built into the car right now, but I have a feeling they won't be powerful enough. I'm planning on using a BuWizz battery pack for power and bluetooth control. The car has around 1200 parts, so it probably weighs 3 pounds or so. I built a four speed sequential transmission into the car as well. For a car of this weight, should I use 4 L-motors? -
Then I realized, that this chassis behaves really well, and started thinking about it as about my new Overland Expedition (or Kostky Trophy) truck. (later I got reminded, that buggy motor is quite hungry, so it can not be used in this kind of event. But, with bigger battery... Have to try.) So, next step was the body. You can see that I experimented with new tire-rim combo. Too heavy, but not bad. And then I finally bought Buwizz. Laziness and worries about custom RC recievers and batteries won. (hope that not for all times :D) I also installed LEDs to the truck. And bought new tires. And finally, last week I took it outside. Hope you like it. :) More upgrades are slowly on the way. ;) -
I'd like to share my most recent model - 1:10.5 replica of 1969 Ford Mustang Boss 429. Boss 429 was the high performance variant of first generation Mustang, equipped with a powerful 7.0 V8 engine. Only 1359 were made, and now there is one more :D Watch it in all its glory: Functions: RC drive - RWD with differential, 2x L motors RC transmission - 4 speeds, sequential, M motor Detailed V8 engine replica with fan connected directly to propulsion motors RC steering - with moving steering wheel, M motor Front suspension - double wishbone Rear suspension - floating axle Openable hood with lock controlled from the cabin Openable doors with locks Openable trunk Adjustable seats (sliding forward - backward and seatback angle adjustment) RC front lights Please watch the video to see this machine in action and for more details. I am quite happy with how I managed to include all the functions without compromising on proportions and interior in a relatively small model (46cm long). The biggest challenges were to fit piston engine over the suspension with the blue air intake under the hood without lifting it (as the result I had to make the hood hollow below the external air intake but still it was tight) and to fit interior over the gearbox. For that purpose I made the transmission very flat with gear shifting shaft actually crossing the drive shaft... (can be seen in action in the video - 2:30) I hope you liked this model. -
An improved version of my RC 3 speed gearbox is implemented into a remote control car. This video shows three main improvements over the previous gearbox design. The first is an improvement is to replace the 90 degree bugatti stepper with a PF servo motor reducing the gearbox complexity. The 2nd improvement is to use a gear rack to replace the liftarm lever mechanism for converting angle to linear displacements. And finally the third improvement to change from using a 2 lego unit axle offset to a 2+1 offset to allow bevel gears to mesh with regular gears for the gear switch mechanism, and thereby eliminating one row of gears. The final gearbox is implemented into a basic lego technic 3 speed remote controlled car that can be driven backward and forwards and steered remotely, as well as remote gear changing between 3 different speeds. -
Hi folks, This is not for purists. Contains modified and non-LEGO parts. My urge to build a super fast LEGO RC Car often stopped at the stage where the body needed to be build. Seeing all the great designs on forums like this, it somewhat discouraged me building my own. Besides the fact that these bodies come with some weight and will not hold a crash a higher speeds, I had to come up with something else. As a result of an earlier project (building a fast LEGO boat) a had some damaged LEGO Hulls (54779). Since a car body works basically the same as boat hull (but 180 degrees rotated), I thought I'd give it a try. Have a look at the result in the YT video. It works fine. Gives strength to the car, the aerodynamics work well for good driving stability and it is not that ugly :) Called it The LBOW (Lego Boat On Wheels). Included standard RC components: ESC, brushless motor, 3s Lipo battery, digital steering servo and .... a Gyro. Resulted in a very fast RC Car. Theoretically this should be able to reach 100 km/h. Speed test will follow (need to find a good track first). For those trying to do similar things, I'd strongly recommend to add the Gyroscope to your car. It prevents the car from breaking out at higher speeds. Very useful.
