What problems are involved in swapping out an old RV-6 HS and Elevators for an RV-7 HS and Elevators? They appear to match exactly except for the skin thickness
I have the 8 VS and rudder on my 6.
..........original tail needed a rudder trim tab...new one does not.
Did you change the incidence of the new vertical stab or did you set it up the same as the original -6 one? IIRC, the -6 was supposed to be rigged symmetrically side to side and the -7 has some amount of built-in offset to counteract P-factor.
I installed a new 7 tail on my -6....both vert and hori--with the -8 rudder.
I also went to electric trim over manual.
I like it, I do have the 0-360 and C/S prop.
One note.....original tail needed a rudder trim tab...new one does not.
