Re-run, look, we are arguing over an issue with a tiny toy car that is part of a hobby we both enjoy. Seems kinda silly doesn't it?
I get your point about the bearing tabs on the diff. case & ring-gear adding needed stability for the outdrives. However, it's not needed as that same stability comes from the gear box holding the bearing in a concentric and stable position. Any slop that exist with the outdrives is because of the difference in O.D. of the outdrives and the I.D. of the bearing's inner race. Since the bearing is held by the gearbox, the tabs do more harm than good because of their grip on the bearing, thus drag on the diff. housing.
No offense meant, and I appreciate the conversation, but we'll have to 'agree to disagree' about this as it seems we both see the issue differently. As you mentioned, it's all conjecture anyway as there is no testing to prove one way or the other. And frankly, I don't care what Dromida has to say. Do you really think they would 'own' a defect in their product???
Bye the way, just finished install and ran one of our trucks with the new brushless setup and modded diffs! All I can say Is WOW! What a huge difference over the brushed motor!
If the diffs. strip in short order I'll report here and consider "eating crow" on the tabs issue.
