No. These axles and this chassis work really well at most weight combo's. The really lightweight cars are just way more fun to drive...
Hi Casey"thumbsup"
I disagree agree with you in regards to the sub 4 pound weight rc crawlers. In my experience, I have found that light weight, sub 4 pound, rc crawlers perform exceptional on smooth flowing rock, i.e.
Natural Terrain. However, the same sub 4 pound rc crawler is inconsistent on rip rap or man made obstacles.
East Texas does not have smooth flowing natural rock. At best we get big boulders piled upon each other or laid out along the ground. Iron ore and sandstone are the most common rock we crawl on here. Add in some dust and humidity...and the traction disappears. It's because of these conditions that drew me to work so much on foam and tire design years ago. The lightweight cars suffer on terrain like this. Too light in weight, and the cars don't have enough contact pressure to hold the line or transition opposing off camber lines, at least in my experience.
I do agree that the light weight cars can pull off some amazing lines because of their nimbleness. And of course, that is fun. But in a competition scenario, what levels the playing field for the machine? 8 years ago when comp crawlers averaged 6+ pounds in weight, those that began working towards being lighter,
such as designs like the very car in this build thread, began to dominate local and national comps. It created a race to be the lightest and that brought added costs. It was the beginning of the end of that era of comp crawling.
I don't know about you... but I would prefer to be a part of an international crawling organization that had basic rules in place to guide the competition in a fair, repeatable, and reputable manner. Weight seems like the first place to start. Every form of 1:1 automotive racing creates classes and they have weight minimums. Just some food for thought.
