Install the battery (not included) and X Factory CF battery strap (1223) using the
4-40 1” flat head screws (6028). With most LiPo batteries 4200 MAh and lower
the battery strap will ‘pop’ onto the posts in the chassis and the screws will
secure it. With extremely high-capacity packs, the battery strap may sit above
the posts – this is OK, the flat head screws will help locate the strap over the
battery and hold it securely. A few extra axle spacers (or the inner ball races
from some old wheel bearings) would work well to space up to the strap.
If you will use NiMh cells, you need part # XF 1224, a CF strap that fits on the
same posts as the LiPo battery strap, but extends forward to hold the two cells in
the forward bay. Make up your pack in a 4+2 configuration, with the four cells in
front of the motor and two up front.
