HSP Kulak 1, 18 First Outdoor Crawling in Norway Weighted up front wheels with 100 grams in each wheel, 2s 800mAh Lipo battery to reduce weight in top of the car. The car is fun to drive, climbs well, but is a bit heavy at the top, needs to be modified for a lower center of gravity, I think. Or just run it the way it is, it works very well
