RotorTech 71mm Tail Rotor Blade Set
About this part
RotorTech blades are finely crafted premium carbon fiber rotor blades from Fun-Key Aeroplane Models. RotorTech blades are designed to be an all around powerful, efficient, well rounded performance oriented blade that will suite a large majority of flight styles from simple aerobatics, F3C, and extreme 3D flight. Additionally, RotorTech blades utilize a minimal amount of paint within the mold, while still providing excellent flight visibility. By using less weight on all of their blades, weight is saved on each set which offers a small boost in performance.

Great tail blades from RotorTech. Bought these for my RAW 420 (by mistake) but they don't fit the grips. I ended up exchanging them for the RotorTech 72mm Ultimates which are the ones that fit the RAW 420 perfectly.
This is my go to tail blade for my Trex 470L. More firm and slightly longer that stock which can help with the low tail ratio of the 470.
You must make sure and check the root size and the hole diameter!! I just got ripped off again the 71 mm blades are different than the 72 mm blades!! I have an oxy4 max bought these things and can't use them!! Hobby shops will advertise 71 and 72 mm blades will work for the same helicopter they will not!! what a pain for 1 mm !!!! Starting to think RT blades are not all that great!!!
Reviewers report mixed fit results for the RotorTech 71mm tail rotor blade set. One owner using it on a Trex 470L found it firm and slightly longer than stock, which they felt helped with the helicopter's low tail ratio. Another verified owner bought the blades for a RAW 420 by mistake, found they did not fit the grips, and exchanged them for the 72mm version. A third owner, using an Oxy4 Max, reported the 71mm blades could not be used because their root size and hole diameter differ from the 72mm blades, and advised checking these dimensions before purchase. The recurring theme is fitment: the 71mm and 72mm sizes are not interchangeable across helicopter models.
