4 HINTSANDTIPS:
4.1 USEBLUELOCTITEWHEREINDICATEDINTHEINSTRUCTIONS:
 Bottompanelscrews
 Screwsthatattachthewedgetothewedgebrackets
 Screwsthatattachthewedgemounttothemainchassis
Otherscrewsusedinthekitdonotseemtocomelooseduringcombat,buttheabovescrewswill
comeloosewithoutusingathreadlocker.
4.2 SWAPAMOTOR:
Youdonothavetofullydisassembletherobottochangeamotor:
 Removethetopcover
 Disconnecttheleadsfromthespeedcontrolfortheaffectedmotor.
 LoosentheM3screwsonthebottomthatscrewintotheendwiththebadmotor
 Loosenthe10‐24screwsontheendwiththebadmotor.
 Slideoutthebadmotor
 Soldertheleadstoagoodmotor,slideitbackin,tightenup,attachtheaxleadapterand
