im going to get the house of balsa acro cub schoolyard kit. i dont know much about planes, so i need help picking a burhsless motor. probably a rimfire, cuz they seem pretty cheep. ill be using 3s lipo. i want the plane to be able to do aerobatics, but not a super fast motor, but more than just a simple trainer motor. i dont know what speed im looking for, as i dont know much about rc planes, so i have no clue what speed all the different models usualy go at. just a mild powered brushless.
