View all Images in thread
insert the berings in the alum tube (i used red lock tite so the berings wont fall out during stab assembly) i tacked the alum tube to the ply wood mount.the long end goes outbrd.
i then mocked up the sub assemblynote the arms are slighty pointed aft. i ground flat spots on the shaft at this angle to have some differential,more up than down
heres the flat spot ,so the aems aont slip on the shaft. i used about 5-8 degrees of differential.
option :i drilled a hole in the LE of the stab ,and added solder strips and some bb's.i then injected some Gorilla glue to hold it in place
yeah it adds some weight but .here you see the stab balanced in a neutral position.full scale do it . helps with flutter and make it easier on the small servos
