Haha that's classic, I'm not sure if it's 100% similar to the losi 5ive-t but there's also 4 screws coming up from the bottom of the chassis into the cage as well.
Just to help out the roll cage and body come off as 1 piece, no need to pull all the panels off. Be cautious putting all those screws back in as they strip easy also take note as the screws are different lengths.
