Hey Sergio,
I have the os 90 4c in mine and to get the cg at 5 3/4 I only had to put 3/4 oz's under the rudder servo. I think when I finally get the other 3 hitec 635's in the tail, I'll be able to remove the dead weight. 635's are heavier then the 3004's I have in there now.

Hey Cee Gee ,
Glad to hear the new hanger is coming along.

SPUDs out...................
