polaris proride rush R/C drive wheel

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:1176871.

an upgraded drive wheel for the polaris proride R/C snowmobile as the stock one does not engage very well due to poor design and is unable to handle more powerful motor/battery. this upgraded design of mine has the engagement fins extended up to the edge of the drive wheel, rather than the stock design which has them sitting closer to the center of the part which gives less engagement on the track.
