WOW! Got the Slash about a week ago and am/was in the process of moving.
I picked up 3 3300MaH packs from Radioshack and am using one of those packs as a doner to make 7Cell packs. It wasnt the old GP cells Shack use to use but, they are GREAT! Got them all together side-by-side using Trinity pure copper/gold plated (avoids corrosion) and TRX connectors.
Before initially running the pack, I cycled the battery (1A discharge/2.5A charge) three times while asleep last night. Did this hoping it would "wake up" the pack so I wouldnt have to...
Slapped'r in the truck and VROOM, off she was. There was a lot of talk about the Slash REALLY lacking in the speed department but let me tell you, it doesnt. Its truely well worth the price.
Running the Slash on a track is going to be great. That is if it can be tamed. Mine hauls...Cheers
