550 blades on a 50?

[NUTNDUN]

DUe to a recent crash I wanted to find out if I would be alright with using 550 blades on my 50v2, I have some extra 550's sitting around that I had gotten before I did the conversion so I figured it would be nice to use em up cuz I am sure there is another crash in my future LOL. I am thinking the 550s would be alright as long as I drop the throttle curves down a little bit.

I'm think it may work, but keeping you head speed down will be a problem. The 50 size motor has mush more torque it will take alot of tuning of the throttle curves and motor to get control of the head speed. Maybe it's easier to buy a new set of blades and safer.
