I hate to be blunt in expressing my opinion, but ball differentials SUCK for any kind of running other than racing. They're finicky, they slip, and they'll burn out on you if you don't watch them. Granted, they're amazing for racing, the adjust-ability they offer is easier/faster/more variable than a gear diff ever could be.I had one in a Losi XX that never gave me a moment's trouble. But in a little 1:18 vehicle which may never see a track, it needs gear diffs like the Helion Animus. I've had two Pro-Pulses to burn up diffs, and this truck I'm afraid might not be any different.
In short, keep an eye on those diffs. Keep them tight but not too tight. Some better outdrives might help too.
If the manual doesn't show you how, you simply pop off a camber link on the side that has the allen head screw, and hold the other side by the wheel. Tighten it up and test.
I have to completely disagree and refure your statement.
Two cases in point are the Associated RC18 that a friend of mine had, he chewed through diffs like you wouldn't believe and I didn't even though we were both running a nearly identical brushless setup. The difference was his was an older one without the ball diffs, mine was a Factory Team with ball diffs. He upgraded to ball diffs, problem solved.
Then my Vendetta SC. I know three other guys with Vendetta Buggies and Stadium Trucks. They did OK with the stock VR3 but as soon as a brushless system was introduced, the diffs melted like butter on mashed potatoes. We ALL upgraded to ball diffs and have had no diff issues since.
The stock plastic diffs are often just too weak to handle anything other than the brushed motors that most cars come with. Heck, even the RC18s now come with ball diffs whether FT or not, brushless or not.
For the record, the diffs on the Animus suck and will melt like a popscicle in July with brushless power.
