This is a spacer kit with all needed hardware, in your choice of color for a ZMR250 quad copter kit:
(ZMR250 frame, motors, and propellers not included).  Included in this kit are:
  • four (4) motor arm spacers 
  • one (1) flat 52mm LED bumpers (supports most programmable LED boards)
  • one (1) flat 114mm LED bumper (support 2 LED boards)
  • twenty (20) M3x20mm bolts.
  • sixteen (16) M3 lock nuts
(NOTE: Bolts may be stainless steel or black alloy, whichever is available at the time.  Every attempt will be made to make sure all hardware is all stainless or black, but no guarantees can be made.  All nuts and washers are stainless steel)
(ZMR250 frame, motors, and propellers not included)
This kit will space the bottom plates 12mm which will allow for your ESCs to be installed there OR installation of a power distribution board (PDB) freeing up more space in the middle section of the frame.  Spacers "wrap" the motor arms to make installation easier.  LED bumpers have tracks to hide wires to the LED boards and provide space for soldering boards together on the longer bumper.  Bumpers also clear the LEDs installed on common Power Distribution Boards for the ZMR (OverCraft and Nucleus).   LED boards are programmable and require a NAZE32 or compatible flight controller running CleanFlight to program.
If you have the ZMR250 V2, please select the 4mm arms option.  If you have the MRM250 V2, please select the 37mm Standoff Spacing option.
 A $5 donation will be made to the Susan G Komen Breast Cancer foundation for each pink kit purchased.
