KRnet> Aileron balance arms

[Phillip Matheson via KRnet]

I have never liked the plans for the balance arm. 
But saying that, I have not heard ( till SA crash) any serious problems. Many 
have found cracking in servicing ( that’s why we Servise them) 
I do my own, 1/8 6061 Alumimium with a gusset welded around the outside of the 
bracket.  Or thin 4130 with gusset, never had cracking And always use counter 
sunk washers
