I have some spare 95 mm tail blades from my 600. Can I use these on the 550 if I stick to the 520 mm main blades?

You can, but I think you are going the wrong direction. better to go smaller. You may have trouble getting your gyro gain set as the tail is going to have a lot of authority.

longer baldes require less gain and give more tail authority.

it's a good thing. (less wear on servo with lower gain)

Longer blades also result in higher mechanical gain (same as moving the ball on the servo horn out), which means less resolution in the tail movements (which could lead to wag in extreme cases).

never had a problem and have always preferred to run longer blades.

everyone at our field has the same preference.

cool, thanks for all the replies guys. I'll start with the stock ones and experiment a little after I get it up and running and work out any initial maiden issues before I introduce the larger tail blades.
