Scale Benson Gyrocopter
When I was a kid my father was good friends with two guys who were pioneers of the Benson Gyrocopter Ed Neleski and Ken Brock. My Dad worked in Ken's shop building Gyrocopters based on Bensons original design and I remember as a kid going out to El Mirage dry Lake in southern California to watch them fly these machines. I saw a video the other day of a 1/2 scale gyrocopter and it really brought back fond memories of those days.
I have done some research and have seen a few designs and I did find a video of a half scale model. The closest one i have found so far is the Minimum V4 that is really cool. I was wondering if there are any other scale Benson designs that are larger than the Minimum maybe 1/4 scale design. Also, is there a source for rotor blades? There was this company called Aerobalsa but sadly the owner passed away in April.
Anyway, I just thought I would ping you guys to see if you had any ideas.
Thanks so much in advance,

The trend seems to be 'fast looking' gryos with cabins[most people don't realize the enclosure/cabins makes little differance to how a gyro flys]
So the old open frame models get less notice and the benson design had pitch stability problem, partically when flowen with a 'pump action' control stick design.
But with training and discipline and height speed restrictions could be flowen quite saftly.
I have many many hours of time on this full seize design[still fly the basic aircommand gyro]
The main problem to replicate a Benson, is the 2blade free teetering head design.
A few members here have successfully flowen this head design[but it is a handfull]
But 2blades joined with a flex plate[no teetering] is quite good[3blades is easier again]
As for blades, there is almost none for big gyros[mostly home-made so far] but there are some people selling small blades.
There has recently been a couple of complete big kits from china, whose blades you could probably use.
If you want to make a benson and blades with teetering head-then there are many good peope here who have done simular already and very willing to help.

Hi Cali! Yes that was the video I saw along with some footage of the real machines being flown out at El Mirage that made me think this would be really fun. Im not sure a 8' rotor span model is in my future but maybe a 4' span would be. Your model is amazing and close enough for me. So here comes the standard question. Do you have any drawings available? Are there plans out there?
Thanks again for building that model and for your post.
