I'm going to convert my PZ UM T-28 to Brushless. I'm going to get the motor and ESC from HobbyKing. There are 3 motors that I'm considering: A cheap Hextronic 2gram motor; a kinda expensive 3 gram motor; and another even more expensive lower Kv 3 gram Motor(Both 3 grams are AP03's.). Maybe even the AP05? Any comments welcome.
EDIT: I don't have much money to use on it, so I kinda want to keep it cheap. What do I need: More torque or more speed? (lower or higher KV)
