Posted February 20, 201510 yr Hi all! It's been a long time since my last post, I have been busy with school. A few weeks ago I builded the standard Mustang Shelby by Sheepo in black with red striping. I tought it was a very nice and detailed model, but I was wondering if it would be possible to make it faster, using only official LEGO parts. Therefore I decided to build, next to my standard mustang a RC version. It turned out very well, I didn't mesured the speed yet, but I think it goes around 15 or even 20 km/h. For propulsion I used 4 RC motors, 2 for each rear wheel. To power those energy slinding motors, I used 2 RC units. I kept the brakes in the front, but even with a XL motor, they doesn't have a lot of braking-power. More at my Facebookpage, even a little test video: https://www.facebook.com/pages/Freskos-Lego-Technic-creations/161905693917724?fref=nf I'm sorry for my bad English and rubbish text, I wrote it in a hurry. A clean, nice and detailed topic will follow! Edited February 20, 201510 yr by fresko
February 20, 201510 yr This looks great in blue and white. Four RC buggy motors should make it very fast! Take out the braking system to reduce the weight, it will accelerate even faster! Never again apologies for "bad English", you make fewer mistakes than most English speaking people, including me. I spell check everything I write and I still get things wrong.
February 20, 201510 yr Looks so good in blue!! Tehre was something wrong with the facebook page, at least for me.
February 20, 201510 yr I'll bet your version will come out quite a bit faster than mine. I don't have the buggy motors.... and I can't justify spending so much on them through BL. I used one non-LEGO RC motor... but is turns out it is too weak. Although the video below shows high speed... then it is actually on the ground it is only about 2x the speed of the original. Faster... but by no means as fast as I would like. I think to really add some great speed, the transmission needs to go. Too much friction. Also the brakes. Great function, super cool that Sheepo added them... but they still rub when not applied and slow the whole model down. <iframe width="560" height="315" src="https://www.youtube.com/embed/gyeRp4y5fzk" frameborder="0" allowfullscreen></iframe>
February 21, 201510 yr Really cool MODs!!! I like how the 8448 wheels looks with the Mustang, but they are crazy expensive ;( You have done a great work changing the parts not available in blue color It is faster that I could imagine using only Lego parts. Have you modified the rear axle in the blue one? I am curious because if you put a lot of torque the differential you can broke the z12 gears easily...
February 22, 201510 yr So I drove my RC'd mustang a bit this weekend, and it worked fine. Not as fast as i'd like, but no twisting of axles, etc. I am not posting it until it is completely finished, and I am still waiting for some parts. But like in this post, if speed is the ultimate goal here.. I'd recommend removing the brakes. Again, great function not often seen in these supercars, but ultimately they hamper the speed and performance. I played with the brakes for over an hour, and now matter how I adjusted them, while maintaining their functionality, they continued to rub quite a bit on the disks. Bad for speed and efficiency. Here is a pic: Okay... lets try this again
February 22, 201510 yr Author Thank you all for the nice reactions... I'm so honored that some very famous builders replied You can see a temporary video on my Facebook page, probably I will film a new video next weekend. In the video, the model was powered by 12 rechargeable AA batteries (12 x 1.2V). The rear of the car is still a live axle, but it has a whole different structure. It uses the same mounting points as the original (excluding the panhard rod). My expirience says that RC motors will function the best using less gears as possible. Thats why the wheels (or rather the hubs) are connected directly with the 'slow' output of the RC motor. I modified the brakes, or rather their return to center mechanism. Instead of using a rubber band to get the RTC, I used 2 hockey springs. My brakes don't rub at any time to the disks. For powering them, I used a XL-motor. Yet, the brakes doesn't have a lot of power. You can slow down a little, but it doesn't give the WOW-effect, in fact: you probably shouldn't notice if you don't know there are brakes. Still, my rubber pieces are completely destroyed, a bit like on the pic of Nerdsforprez. Fresko
