RE: spot welding and simulators.
Bobber, I don't know what to do with the bobcat but I will soon create a unique model of it with the current one as a starting point. I've only had a crack at fly the bobcat a few times and from what I remember you are right. It seems too heavy and that is where I would start. Good things come in small packages. The availability of free open source models for this simm is astounding. There are so many great jets too!~).
