Turbo Ice Sled (experimental)

thingiverse

The impeller won't propel the boats as quickly as I wanted. So I began looking for another method to reach higher speeds.\nAn ice sled generates less friction drag and indeed, it zooms so fast that I could barely maintain control over it. Full throttle was only possible for a few brief moments. If you give too much gas in curves it will make an abrupt U-turn, though it is actually a fantastic emergency stop ;-)\nIn any case, the indoor ice rink was far too small to allow full speed or I have a lot more practice yet to do...\nIt's absolutely necessary to use a bumper; otherwise the sled can collide with the transmission gear of the servo and cause serious damage. This happened to me when the sled skidded uncontrollably into the edging. I recommend using a bigger servo, they are also cheaper anyway.\nI know that winter is now over, but if you find an ice rink and ask politely, there may still be an opportunity ;-) \nI'd like to express my gratitude to the very friendly and helpful management of the Eissporthalle Frankfurt/M. http://www.eissporthalle-ffm.de/ \nThe files for the impeller can be found at: http://www.thingiverse.com/thing:274054 \nhttp://youtu.be/jeEbWfG0DLM,http://youtu.be/YKiEc8oZmRY \n10.04.2015 Today we attempted another run. https://vimeo.com/124606751,https://vimeo.com/124607071\nThis was followed by a quadcopter. https://vimeo.com/124607242,https://www.youtube.com/watch?v=zmdHoqwC7w8
