yep - extreme core - send it back and go with xtreme, not extreme

some people stick with extreme core as a challenge to their mechanical skills - i think you have to use all extreme core stuff with no substitutions - especially watch the lower bolt head screw placement

until you have broken the heli down completely a few times so you know how everything works together, i would put it aside and get xtreme products instead - check at ushobbysupply.com
