i was wondering if anybody else has brown their servo saver steering arm/linkage? just broke mine today, and was just wondering if there was anything else to replace them with, or just the stock. also i was looking at my friends crt 1/8 and notice that his chassis brace on the front and rear are both alum. and on my crt .5 they are plastic. so was wondering if there are any alum. upgrades for it.
