Nice, looking conversion. Yeah I have been running my ST-RR conversion for some time now and love it. One of the best handling truggies I have every driven and I attribute some of this handling to the chassis flex. Most buggies/truggies are designed to flex, that is why the braces stop short and attach to the middle of the chassis (and not to each other). Without this flex it would feel like a brick. I use the King headz braces only because I was worried the stock Kyosho brace might pop off (held on with a large ballend) and so far they are working great. So don't worry about the flex, it is a good thing.
