freakwave Posted January 24, 2013 Posted January 24, 2013 Finally my first MOC-post here in this forum! Since some days we've got some snow again and that calls for some LEGO outdoor activities. As my snow-groomer is in a state that would require serious work, I decided to go on something simpler, a snow-mobile. Problem with LEGO motors is that they are a bit slow. But hey, there was the RC-Buggy in the corner! So the RC motors and the unite became the base of the snowmobile. Dry tests proved it to be quite powerful and drive the track very fast! The RC motors are mechanically coupled and interestingly I had first issue with this coupling. Putting the speedometer on them I discovered that some RC Motors have less RPM than others, but those two "flavors" of 5292 have among them pretty stable RPMs so after swapping them to two of the same, it drove perfect. So here's the first result of the outdoor capable Snowmobile. Working right now on the steering which is a bit tricky. Due to the slanted steering column the skis cut into the snow aleady, which is good. But to have it turn properly it should shift the weight a bit, i.e. lean into the turn. In real life the human on top help to perform this feat, here, something simple needs to be developed. The first tries nearly achieved this as due to a short rod, it pulld the legs up when turning too far! Here are some pictures and a video: Quote
Alasdair Ryan Posted January 24, 2013 Posted January 24, 2013 See if you made the middle pivot via a turntable that might help with the steering. Looks good so far. Quote
Paul202 Posted January 24, 2013 Posted January 24, 2013 That cool, makes me wish I had some snow instead of just gone-chilling weather. Quote
timslegos Posted January 24, 2013 Posted January 24, 2013 I wish I had snow where I live . Looks great though! tim Quote
Jeff Schield Posted October 12, 2013 Posted October 12, 2013 That is a huge model. Impressive scale to work with. I like the video. Quote
Doc_Brown Posted October 12, 2013 Posted October 12, 2013 (edited) I was going to say sad batteries! haha Great start! I'm looking forward to seeing how it goes. So wished it snowed here eh. :) Just noticed you are driving it from the high gear output, i would say thats a bit too much for it on snow. it will struggle i think.
