Default is a 75 amp speed control too big for 450 heli?

I just bought my first high end sc for a mini titan flybarless heli.I chose an Castle creations ice 50 but my motor is a turnegy heli drive sk3 competition series, 3 align ds415m digital servos and the fbl unit.Now the info on the motor says it draws 50 amps max.Now some guys im talking too say that could push this $86 esc.I spent that kind of money for bullet proof.Is it insane to slap the ice 75 on the heli instead??? i have the store holding the order until i get a pro oppinion.Thanks

Extra capacity is good.. certainly, if you really are going to draw 50A, then a 75A ESC is a far safer bet than a 50A one.

Too big as in too high amperage.  No.  Too big as in too heavy?  Maybe.
