I think many orni-fans would like to have the possibility to make a copy of your fantastic ornis. I don’t think it is necessary to produce ornis ready to fly but many like to have the possibility to be able to build the Kestrel from your instructions.

How to make is same as ---Making of Pteranodon 5-6V.
Material cost without NewGLDAB is about 12000 yen(158USD:1USD=77yen)+Postage.
+Motor(950yen)+reciever+servo*2(5200yen)+ESC(900ye n or 2200yen)+New GLDAB
And your skill.
