Porsche96 Posted July 21, 2014 Welcome everybody :) Today I’d like to present my new MOC, which was built especially for a contest on LugPol. Porsche 918 Spyder Specifications: Scale 1:10 Length 58s / width 27s / height 13s (46,4/21,6/10,4 cm) Weight: 1800 g Independent suspension 4 steered wheels 4 wheel drive Functions: Driving (RC) Steering (Servo) Tilting spoiler during turning V8 dummy LED headlights Openable mask, bonnet and doors History I started the building of the model 2 weeks ago. In the first week I created the chassis and in the second week the body. The main goal was to build a sports car driven by RC motor with four wheel drive. I was watching different car models, I wanted to build a Lamborghini, but at the Brickshelf there are lots of them. So I decided to build Porsche 918 Spyder, which, similarly as new 911, has 4 wheel steered. The contest assumed that you can use only 2 motors. So to the maximum use of motors I decided to built a spoiler which works like the Pagani Huayra’s one – during turning one side of the spoiler goes up, e.g. the car turn left and the left side of spoiler goes up. Driving Porsche is driven by single RC motor from the slower output with ratio 5,5:1. There are driven four wheels using three diffrentials. Steering To steer I used servo motor. There are two steered axles: the first with ratio 1:1 and second with 2,8:1. To the axle responsible for steering of the rear wheels there is a connection to the spoiler which goes up during turning. Suspension The independent suspension is based on the Lego arms. On each front wheel there is one spring from the yellow absorber 6,5L and a rubber band connected to the arms. In the rear wheels for depreciation there is used one yellow absorber 6,5L for each wheel. Some photos Gallery Share this post Link to post Share on other sites
Zerobricks Posted July 21, 2014 Not bad :) I would suggest you to move the spring closer to the center of the suspension arms, to reduce friction. Share this post Link to post Share on other sites
jorgeopesi Posted July 21, 2014 (edited) Awesome for a 2 weeks work . I just noticed, I used the same doors for my Huayra two years ago . Edited July 21, 2014 by jorgeopesi Share this post Link to post Share on other sites

grum64 Posted July 21, 2014 You built this in 2 weeks? Awesome. Just Awesome Share this post Link to post Share on other sites
Rishab N Posted July 21, 2014 Awesome realistic work. The four wheel steering is a nice touch similar to the real car Share this post Link to post Share on other sites
Paul Boratko Posted July 21, 2014 Very Nice Job..!!! Have you had any issues with the Bevel gear from the motor skipping off of the Bevel gear from the center differential..? Share this post Link to post Share on other sites
Porsche96 Posted July 22, 2014 I would suggest you to move the spring closer to the center of the suspension arms, to reduce friction. Thanks for the suggestion, I will use it in my next MOCs. I just noticed, I used the same doors for my Huayra two years ago Actually, I didn't know about it :) Have you had any issues with the Bevel gear from the motor skipping off of the Bevel gear from the center differential..? No, I haven't. The differential is located in the frame 5x7 and there are two bevel gears in both sides of the differential. Thank you all for your nice words :) Share this post Link to post Share on other sites
