Hi Rich. Thanks a lot for your reply. Sadly I am in South Africa so I won't even consider asking you, but I appreciate the offer. Out of frustration I reduced the width of my blades from 60mm to 52mm, which I got from Steve Jones 2's posts on page 7. Even though this did bring the CoG forward slightly, it is still too far back. I will take a photo and put it on. I was so excited about finally finishing my Atom. I will order some more wood as soon as somebody can bring some, as I live in a very small town. Maybe the weight of the spruce was too light compared to that of the balsa?

Hi all. Hope you guys are well. So, in 2015 I started building the Atom, but everything came to a halt after the birth of our twins. Recently, after being stuck at home after an operation, I decided to unpack my building stuff. All that was left to do, was make blades and cover the atom. The blades are getting me under though. Seriously. The three "blanks" weigh 27g, 26.9g and 25.8g. So, wood selection was okay. Off to shape them to profile. Dimensions are 60mm x 450mm. Actually not as difficult as I thought. Then I came to finding the chordwise Cog. And this is where I am stuck. The chordwise CoG is just too far back. Instead of the triangular FG plate I made the revised one from a pdf that I got from another site from Rich H. If I understand correctly, the mounting hole should be 430mm from blade tip, 1mm behind the chord wise Cog. In saying that, I suppose every blades' mounting point should be the same? I don't want to sand down too much more towards the rear of the blades, out of fear for losing profile. The Centre mark of the blades were all within 3mm so obviously my initial sanding was not too bad. Please help?

Hi Steve. Thanks so much for your reply. Okay so at first I will stick to a square root and see how that goes. I found some pdf's on another forum for a slightly modified FG plate on the head. Instead of a triangle its slightly more square where the 3 blades attach. But for now it is blade making for me. As a real life heli pilot the concept of making blades boggles my mind as I know how precise they have to be. Actually had a bery scary experience just last week with a heli tune where one blade's tracking was waaaay out. But anyway, thats me off topic. I will post some pics of my blade attempt soon.

Hi all. So since I last posted, and sadly, built, I have spent 4 months away from home for work. And then also been getting the nursery ready for our twin boys who should be arriving shortly! Okay so 0.8mm sheet for the head received from HK. Also, laminated my 6x6 spruce and balsa for the blades last night. So here is my next question. Actually two questions. Firstly, Steve Jones 2 has some pics early in the thread on his blades. At the root I see they are not square but runs slightly diagonaly from TE to LE. Dete Hasse I see yours is square? May I ask why please? And then is there a template somewhere for how the blade narrows towards the root? Regards Hendi

Thanks Bob!

Hi all. Between Rich, Dete and Steve Jones 2, or anybody else, is there maybe a pdf floating around that can help me with making my own blades? Kind regards and happy landings

Hi there Richard and Dete. Thank you very much for the advice and help. Unfortuntely work has been keeping me extremely busy and away from home. Hopefully I will be able to carry on the build from this weekend. Happy landings Hendi

Hi guys. Hope you are all doing well. Is there any other option for the 0.8mm triangle for the head? I am realy struggling to get hold of a sheet like that over here in SA. If I can just get that sorted together with the blades. I have never attempted to make my own blades so this should be interresting. Unfortunately with our wonderfully strong Rand ordering blades from AJs becomes quite expensive. Happy landings

Hi all. I have finally decided to start building the Atom. It will be my first steps into the world of Autogyros. Just a quick question... how do you setup your Tx for Autogyros? FW or Heli? Looking forward to the project! Happy landings Hendi

Hi all! After 9 months of contemplating, I have finally decided to take the plunge. I am currently scratch building a Piper Pawnee but after some frustrations I needed to get my mind off it and I think the Atom will be an awesome challenge. Quick question though... Is there any special setup needed for your Tx? Do you setup a fixed wing model or a heli model? Kind regards and happy landings Bossie
