not yet, i ordered 2 sets though. i was using the ofna/jammin ones which are about 1mm too big/ they work for a while but i'm going through gears in the diffs like crazy, no leaks tho. i check mesh, fill to the right spot, check mesh again, used longer screws even. every gallon or so one of my diffs blows one of the large internal gears, just flat. this last weekend it was the rear during qualifying then the center went at the start of the main. i'm gonna redo all 3 for this weekend to test, then rcpro race in 3 weeks. woohoo. i'm gonna do some lightening this time on the st, cf shock towers, turnbuckle chassis braces, hyper 7 front upper mount. we'll see how it goes.
