Mine has 8 packs through it so far and going stong! I took my buggy to the track for the first time yesterday and by far had the fastest thing there. the back half of the track is a dirt oval. I was up on the drivers stand with a few nitro buggy guys doing the oval. I was tailing a losi for about 10 laps until I got the hang of it. the losi driver made a snide comment about :I thought brushless was fast. Coming out of the next corner onto the straight I pegged it and shot around him and about 20 buggy lengths ahead going into the next corner and lapped him 4 laps later. :)
