I just made up some weights to fit either side of the short LiPo along with a plate that fits underneath the battery.
In rear motor config, the ESC shelf / battery box doesn't allow for any under LiPo weight (depending on the height of the LiPo) - but with the 96mm battery fitted fully forward, you can still fit weights underneath it.
The 150g Gnarly is a combination of an 80g under LiPo weight plus the sdie LiPo weights (each 35g).
