By the way.....I did not do the brushless upgrade. With the gyro, it's a pretty good flyer. I use it as my "learning / front yard beater bird" I am in the process of building a T Rex 500 for serious flying. I dont think that throwing cash at the blade will make it a "Great Heli" It is what it is !
Good to learn on and beat up so that I dont have as much anxiety about flying a more expensive CP heli.
