CA M249 Para ---- Lipo Size!?

[ThePope]

Afternoon all,

Wondering if anyone can help me? I have acquired a new CA M249 para however it suddenly hit me I don't have the foggiest idea what size lipos fit inside the hand guard? Has anyone got this or the A&K version and if so what is the biggest size lipo I can fit in the hand guard?

Thanks for the help.
