Has anyone tried removing the battery tray and side guards all together? I took mine off and was thinking about a different way to mount batteries. Tekno makes some trays I'm debating on that only weight 25 grams so both would be 50 grams plus a couple for velcro straps. the stock versions with sideboards hardware and the carbon straps instead of doors weigh 160. 100-110 grams reduced sounds pretty good.
