This is going to be a long review so please be patient and read it through. And to begin, I have not flown the set of blades at this time.

There are some large-scale heli projects in my shop currently and more planned for the future so having a source of extra large rotor blades, at a reasonable cost, is a must. These carbon blades, advertised as 930mm long, have a definite purpose. But now that I've had a chance to hold and inspect them, I'm not sure where they are going to fit in.

Let's start with the claimed specifications and my findings:

Length as advertized: 930mm. Length as measured: 907mm.

The length that matters is from the blade's tip to the bolt hole and here it's 907mm. Whom in their right mind cares what the overall length is? Let's stick with a specific measuring standard, OK? If a distance from the absolute blade root-end to the hole is given, that's fine but the *effective* length, the one that matters, is from the hole-to-tip.

Grip thickness as advertized: 22mm. As measured: 21.93-94mm.

Plenty close enough. The only blade grips compatible with these are made by Vario for their line of very large-scale heli's. The Robinson R-22 comes to mind but these blades, although close to what's required for it can not work on that or almost any other Vario model. Why? Because the majority of their airframes are designed for left-hand rotation rotor blades only.
