i'm new to helis and new to forums.i've been flying glofuel planes but have been fascinated with helis.bought a used axe cp from one of the guys at the club.i want to keep costs down as much as possible, don't have to tell anybody out there that rc anything can get expensive.i have been using a 1250mah lipo battery while trying to learn how to hover.the heli got tangled up in some star jasmine and i saw smoke.the motor has died.i want to upgrade to a brushless motor but i want to know if i will need to chage anything else (also new to electrics).i have questions regarding size of motor,new pinion gear,new main gear,new esc.bottom line i guess is can i squeek by with just popping in a brushless motor?
