gonna need a custom battery tray from mike and i already ordered the zippy 5000mah 5s pack witch is 160 x 51 x 40mm and i dont want to mount it on its side how big should i have him make the tray? also the .25 cut out on the bottom of the tray is that to go over the mud gaurds or just so u can mount it close to the lip. am also looking for the side mudgaurds but can not find them anywhere. can anyone help?
