74mm tail blades hold Align T Rex 470LM solid like a stump!!
Align parts are of excellent quality And fit perfect. You cannot go wrong with these blades!
I’ve put several hundred flights on my 500Xs and found these blades work very well. I even tried much more expensive carbon blades that didn’t perform any different.
Very pleased with these blades
These blades are a MUST on the T-rex 470L. Corrects for the weak thrust from the poor tail gear ratio (3.73:1). These blades are affordable, balance perfect and are VERY durable. I've taken my 470L into the ground 3 times, and I am still on the same 74mm tail blades! If you own a 470LM/LP/LT, these are a MUST for a much better tail PERIOD.....
I read that others had better luck with longer tail blades, and my first couple of flights, I also thought tail needed more authority, especially at lower Head Speeds. I've yet to fly these, but it should be an improvement. Same quality as the stock blades
