First off chuck away that 310 engine,, its a missfit for the aerohawk, either stuff in the original or get a coreless
www.mikromotor.net sells this configuration with their PRO version, consumes about 30% less power and gives about 40% more spunk over the stock,, its pricy but still cheaper than any brushless option as that would require all new electronics but it will last 1000 of hours without burning out,, most other engines will be more of a stepp sideways than forward,, the stock enigne is pretty optimal as far as brushed engines goes without doing major upgrades to everything else.
