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. 

Rotortech "Ultimate" Blades are a unique design concept from the owners and factory pilots at Fun-Key. Featuring 700mm of length, 63mm wide chord, a 14mm Blade Root, and an inward focused CG for excellent agility, and delayed stalled characteristics.

I tried these on my 6S SAB Piuma, and I'm in LOVE! The stock blades felt sluggish, but with the RTU blades it's quick and poppy, but still locked in stable. I have no idea how they make a blade feel so stable and be so quick, but they do. Magic I tell you, it's magic.

One amazing rotorblade. Both collective and cyclic became crisper and stronger.
They stall very late and the low MOI is insanely good for nitro/gassers.

This is currently my very favorite 700 size blade. These are some specs:

Weight: ~207g
Spanwise center of gravity: ~325mm from blade bolt
Chord: 63mm
Root thickness: 14.3mm
Bolt hole: 5mm

I am using them on a Kraken and a Tron 7. I like how I do not need blade shims/spacers with these blades. They are a bit louder (fartier) than VTX 717 blades, but much quieter than SAB BT 690 blades. At similar head speeds and flight style, I get about 20s longer flights than with the VTX 717s. Collective punchouts, agility, FFF and big air tracking compare very well with VTX 717s; I cannot tell any difference between them. They autorotate very well, but the VTX 717s have slightly more hang time.

I love the color scheme especially when matched with RT Ultimate tail blades. I am very happy with these blades.
