| Subject: | Wing remove/re-attach. |
--> RV7-List message posted by: "Hinde, Frank George (Corvallis)" <frank.hinde@hp.com>
Hi all,...I was just in an IM conversation about the above and thought I
would re-post here in case it helps someone.
I made what is (according to Van's) the classic mistake...I forgot to
trim the rear spar wing attach points before I had all my remaining
friends help me install the wings. This resulted in a 1 1/4" forward
sweep...Now personally I think the Extra 300 looks kinda cool but RV's
are not supposed to do that!
So now all my friends are at work on my day off so how do I get the
wings on and off by myself?...See what I did below...

RV-7A...It Looks like an airplane!
Actually its pretty easy after you got past the out burst of emotion
that you screwed up!
Made a sling (old climbing rope) to hold the root of the wing..suspended
from roof rafters
old office chair on casters secured to tip of wing (no tip installed)
Using a ratchet strap thru end rib holes round back of chair...Chair is
really good cus it is height adjustable to line up the dihedral!
undo bolts...pull...wing root drops into sling
sweet
Up onto sawhorses...One end at a time...:)
Reverse to re-install
easy!
Actually after I done it twice I realised it really is very safe.....as
long as the sling holds
I made mine adjustable by using a ratchet strap in the middle of the
rope...That way you can micro adjust the height for re-insertion
