As of last post I made the mark 2, which was a redesign from the original prototype (Mark 1). After receiving the much need parts that I thought would make mark 2 (Figure 1.1 - 1.2) more range worthy I ran into major problems with lack of torque. If I add in the required part to get to the 15' that is required in the product specifications, the mousetrap spring would have so little torque that it didn't even travel past 6'.

In an effort to diagnose the torque problem I moved back to the smaller wheels (Figure 1.3-1.4) which bumped the travel to about 10'. The only problem here is that with my calculation the care would only be able to reach 12' at most and obviously that is not the case missing the max distance by 2'.
