that website has been hacked a long time - I don't even know, if it's been hacked, un-hacked and hacked again.
I even tried starbeegyros on Facebook - with a strange result. I'll have to call him/them.
Thanks to Scott Essex I am now in contact with Dana Linn.
They had problems with their DSL (internet line) and their mail program.
I contacted Dana Linn through his principal company and very quickly got an answer.
I was worried, but all is now well.
You could give some consideration to using a seat tank. From the weight standpoint, I found that there was very little weight difference between seat, plus seat supports, plus fuel tank, plus fuel tank mount, compared to a seat tank and support. It does move the cg forward some though.
There are many Gyrobee types flying with CalumetAir seat tanks. 'Bee mounting instructions, provided by a customer, are available on my website www.calumetair.com The mounting instructions on the site advocate bending the U tube ends. I suggest using U brackets to mount the tube to the airframe (like most contemporary mfgs do)
