I just ordered my first 1/5 scale buggy, a Rofun BAHA450, and am wondering about the diffs. With my 1/10 nitro trucks I've upgraded to ball/limited slip diffs; is there a 1/5 counterpart? I've seen lots of alloy replacement diffs advertised, but none specified as ball or limited slip. Based on the Rovan parts diagrams, they have typical planetary gears; a 2wd would be much nicer than a 1wd.
