ZMR250 V2 Build Manual

Quality, Affordability, Convenience!
Congratulations on the purchase of the ZMR250 V2 Mini FPV Quadcopter! This mini quadcopter is a ton of fun
and building can be a really enjoyable experience too. We hope this manual will assist you with your build.
ZMR250 is probably one of the most popular FPV quadcopter frames. We have taken the time to make sure that this is
the ZMR V2 you want. We have reworked the frame to include both top and bottom plates are "true" 2mm plates. We
have also taken the advice of many and included 4mm thick arms. These arms are included in the package and there is
no need to buy them seperately.( 4mm arms can be found running anywhere from 6-15 dollars each!) They are
included in this package.
Our carbon fiber has been sourced and quality checked to ensure that you are getting the best quality 3k carbon fiber
around. Including a full PDB w/LED lighting system you cant find a better deal out there! Introducing the ZMR250 V2!!!
