Turbo Ice Sled (experimental)

myminifactory

The impeller isn't propelling the boats as fast as I had hoped, so I started searching for another way to gain more speed. An ice sled results in less viscous drag and indeed runs extremely quickly, making it difficult for me to maintain control. Full throttle is only possible for a few seconds at most. If you apply throttle in curves, it causes the sled to make an about-turn, although this can be a useful emergency brake. Nonetheless, the indoor ice rink was too small to allow me to reach full speed, or I have a lot more training ahead of me... It is absolutely necessary to use the bumper, otherwise the transmission gear of the servo may become damaged. This happened to me when the sled slid uncontrollably against the edging. I highly recommend using a bigger servo, as they are cheaper anyway. I know that winter has already come and gone, but if you find an ice rink and ask politely, there still might be a chance. I want to express my gratitude to the very friendly and helpful management of the Eissporthalle Frankfurt/M at http://www.eissporthalle-ffm.de/.
