You need to have a close look at a hellfire first, there is not a lot of room on the chassis for lipos, that is one of the reasons why i chose to convert a Jammin crt instead, maybe you have some better ideas on where to put stuff, it looked like a more challanging conversion to me. I am sure it can be done though, the new kyosho MP777ST-R would be a cool conversion too.
