Yep, the 8K is a lil bigger than most I see on here, but I am giving the truerc lipos a try. Since they are not 20c packs, I kinda had to go to 8K IMO. Plus, I typically run multiple vehicles at the races, and having extra runtime is kind of a buffer for me having to charge all 3. So, the downside is the pack wants to sit higher than the body. But, its nothing I can solve..so we will see.
