I have the original VP CVD's, not sure what they were named but they were the first ones. No problems yet, but what are the differences between what I have and the newest ones? IE is it worth the upgrade? Running 3S BL, 21 turn motor for now, but maybe the 3100k tekin roc soon.
More material was added around the pin slot as well as where the pin goes through the stub axle. Almost twice the material as before in the areas where problems were seen.
If they haven't failed you yet, keep running them! The day to day performance will not be different, just the overall strength.
