All I have left on the tail kit is the fiberglass tips. I want to smooth them out with fiberglass but was a little confused on the balancing part of it. I thought I read you balance them when they are installed on the fuselage but I see others do it well before that. When can I install them and how should I balance them. Another thing, how do you add and remove weight once they are installed and riveted on? Will painting them affect the balance enough to mess with? Just want a little clarity on this part. Thanks
