The "Gyrator"
Hi Phil,
Thanks! I hope I can get it to fly better, everyone at the field liked the way it looks but the flying has got to improve.
I see Randy W. is online now....he's probably saying "I told you so" 'cuz he did! Early on when I was in the the early design stages, he answered all my newbie questions patiently and succinctly but all through the answers there was an underlying message: make sure it's LIGHT! I've been designing & building successful 1/2A powered designs for years now and until now all of them have come in lighter than planned. This one has fooled me...there's just too much light ply, plastic and steel in it! I have some stuff I can throw out or replace and I think I'll make it yet.
I used a Clark Y airfoil on my blades, shaped pretty accurately. I made a CNC cut formica template to make sure the top surface was accurate and consistent on all blades. I have the SG6042 coordinates and will try to reproduce it on my new blades. It's gonna be tough to get that undercamber into hand carved and sanded blades though! I hope the SG6042 will work with the small chord I'm using. With the success you're having, sounds like I better try.
