Nope, it's only for a scale look if you are flying a fuse that has more than two in real life. More than two and you start to lose efficiency and you will need to run a 3 axis gyro since there is no flybar. Just stick with two, you will be much better off.
Yea, I did'nt plan on changing, i was just ordering some parts and seen those and could'nt believe the prices,Just wanted to know why someone would get one.
