Lime supercar with 3rd party parts
JJ2 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello everyone, This is my new MOC, it is my third creation using non-Lego parts. Without the body was the fastest out of the three going over 20mph-32kph but with the body it only went 17.4mph-27.9kph which was included in the video. This project was started when I bought the 8880 style hubs from Efferman on shapeways and evolved to also use the non-Lego electronics. I also used the high torque differential, 550 motor mount, and the CV joints for the 8880 type joints, designed by Efferman. This was also my first creation to use my custom designed part, the 5x7 frame for bearings IMG_1130 by JJ2Sam, on Flickr I went with a lime and black color scheme on this one to give it a pop of color compared to my other, more bland creations that are white and black. IMG_1131 by JJ2Sam, on Flickr I worked a lot on the front to make it look menacing like most real supercars often do. IMG_1132 by JJ2Sam, on Flickr With the custom hubs I was able to make the gaps around the wheel very small but still have it where it does not bind. IMG_1134 by JJ2Sam, on Flickr I covered up the bottom to stop dirt and other debris from getting inside the gears and motor that would cause the parts to wear faster and also shorten the life of the motor. IMG_1150 by JJ2Sam, on Flickr Here is a picture with the tape and body removed. I mounted the motor and other electronics as low as possible to keep the SOG low for better handling. The gearing is 9:1, there is a 12T gear mounted to the motor and a 36T going into my 5x7 frame with bearings, along with lithium grease, that made the drive chain have almost no friction. With such low friction the motor almost never got hot and no drive parts were damaged even after me driving it on a bumpy road and some crashes. IMG_1149 by JJ2Sam, on Flickr The hubs seem to have blended into the background in this picture but here you can see the rear assembly, I made this creation modular where if you remove the two black beams connected to the two dogbone pieces on each side the entire rear axle could be taken for maintenance like regreasng if any was needed. IMG_1148 by JJ2Sam, on Flickr IMG_1146 by JJ2Sam, on Flickr The front axle was nothing special, just two wishbones with different lengths and so on.... The performance was good but it did tend to pull left or right dew to the slack in Lego parts, but there is nothing you can do about that... Finally the video
