I don't know a lot about dragon wings, have they always been vr12 or is that only the newer rotors?Notice the total freedom from airframe shake on Joe’s Aviomania gyro that usually acompanies rotor vibration.
The rotor is Dragonwings of 9” chord using a Boeing VR-12 airfoil and with drag struts to stiffen it inplane.
The absence of 2/rev is explained in my post #82 in the Swedish Yoke thread:
'Ol Otto probably used bamboo because..... that's the best material he had from which to choose. If he had aluminum available...... I bet he would have used it. Heck, maybe Otto would have used a 3D printer. Bamboo is not homogeneous; you're right, no 'aviation grade'.www.rotaryforum.com
I really don't have an ability or desire to make a comparison. I will say that I have flown regularly from a grass strip, I have taken 435 pounds in the summer and had no problem lifting it. I have flown 445 once (combined weight me and pax), from a hard runway, and do not believe I was anywhere near its limit, although it is my limit. And it is the smoothest 2 place I have ever ridden in.How is the VR-12 performance? Did Ernie ever try VR-7?
I am almost a local, Wolfy. My great grandpappy’s Georgia militia unit was called to federal service during the Seminole Indian wars of the 1850s and he received a land grant along the Florida-Georgia border for that service. Global cooling resulting in major freezes in the 1890s wiped him out and my grandpappy moved south around the turn of the century.I used to spend some time on cattle stations up north (as we call it) which was about half way up Western Australia in an area called the Pilbara.
I was only up there in the dry, and the hottest I have seen was 48.9 c (weather station on the neighbouring station) but it's dry heat so it's no worries for me. But get that humidity up at 90% and even 25 c is no fun, full respect for you fellas that live like that.
Sounds like you have been there long enough Chuck to be almost a local.
