cheers - often the crane stocks have "about" a 20mm tube by "about" 125mm or 5 inch length for 2 sticks
BUT it is so difficult to just say this or that will work for deffo unless I start digging through the exact gun type
(which a number of my guns now have stubby's on them instead)
some can go up to about 21 - maybe 22mm at a mega push - a cyma seems to a little larger & square rather than round space
Nothing worse than buying a battery that you find out it JUST don't wanna fit - done that classic
so where ever possible - try to make up a bit of cardboard/wood - anything a similar size n shape and see if that will fit
plus a bit of room for wires etc.......
a pig of battery gun mofo has to be the mp5k - its long thin tube that really has a max of about 18mm tube
plus some stick batteries with a thick wire running down outside of the old skool nimh seem to stop many batteries that should fit
reall pain in butt stock that gun for batteries
