Rotor weights of diff. mfg's

[Brian Jackson]

When comparing rotor blade weights of various manufacturers, does this generally include the hub bar and blade grips (retention straps)? The reason I ask is because I'd like to compare weights between 23' Dragon Wings rotors and 23' Sport Copter (7" chord) rotors. I'm aware that the Sport Copter rotors are a bit heavier, but I don't know by how much. Anyone have this data?

Thanks,
Brian Jackson

The rotor weights should include their all up flying weight. Which would include blades, hubbar and all the bolts and hardware necessary to hold it all together.

As an example McCutchen used to list it's rotor weights on their web page. The difference in weight between the 21' (62 lbs including hubbar) and 29' (80 lbs. including hubbar) blades was only because one set of blades was shorter.

brian, sorry to hijack your thread, it happens that your question is also interesting to me :(
chuck, what makes this big difference between these 2 rotors ?
the weight should be intended ready to spin ..
on your opinion is 80 lbs heavy ?
thank you

Dragong wing floats alot so landing manage correctly looks to the by standers as 0 airspeed. MCCutchen flots but it get to a point that drops you. the spin really fast. My opinion is learn to fly what you wallet can aford .

If I remember correctly, a set of 25 foot, 7 inch cord SportBlades are about 52 pounds, 23 footers would be a few pounds less obviously.

I seem to remember my 23' Dragon Wings weighing in at 42 lbs. with hub bar, straps, and hardware.

I can't remember what my 24' Rotordynes weigh.
If I get a chance, I'll weigh them this week.
