It's obviously been repaired several times in the past. First, you need to determine if those prior repairs seem mechanically sound.
The missing chunks of rib can just have scrap balsa glued on the sides to fill in, then kinda match that scraps profile to one of the still good ones.
From the pics, the only repairs, other than recovering it, are the missing rib chunks.
The trashcan at the local flying field is usually a good source of scrap balsa to make repairs with. People are always stuffing their wrecked remains in the trash. Even the worst crashed ARF will have enough small bits of balsa to make the kind of repair this wing needs

From the pictures, its hard to tell if the front half of the wing was sheeted (from the spar to the leading edge). Many trainer wings are because it adds a lot of strength to the leading part of the wing. If the strip on the top is raised above the rib edge, thats usually a clue that it should be sheeted. Sheeting takes a little more time, but isn't difficult. Rather than trying to type out a full description, you can probably find lots of help by doing a search on wing sheeting.

I agree with cutaway on the rib repair, add a servo ( second picture), nad before covering, remove all the covering and sand! Looks like it has been recovered at least three times. I dont believe the leading edge has ever been sheeted on this particular wing, the wood at the leading edge of the ribs would be thicker to accomodate the thickness of the sheeting. sounds like your doing the right thing by being trained, good luck with the repair!

Simple to fix those ribs. First get some 3 by 5 card stock and put next to the good rib. Carve off those gobs of glue on the LE and fit your car stock in, then trace the front of the rib.
Cut some 1/2 ribs out of the appropriate width of balsa. Use these to replace the badly cracked or broken ribs. I recommend sawing off the old rib about 1/2" out from the spar and gluing the replacement to this and the leading edge.
Voila, Strong and light. Looks fine.

Two articles about wing repair:
http://www.rcuniverse.com/magazine/a...article_id=998
http://masportaviator.com/2005/10/06/arf-wing-repair/
Very important: do a lateral balance after you finish your repair and covering:

A few years ago I wrote an article that's in the RCU magazine section called [link=http://www.rcuniverse.com/magazine/article_display.cfm?article_id=910]How to: Wing Repair[/link]. It came about from some repairs I did to an Alpha 60, and may be of interest to you before you start repairing your wing.

From the looks of things you're primarily looking at a recovering job.
That is not terribly difficult, but it may be something out of reach for a novice.
You have two choices IMHO...
1. - Find a local club and get a more experienced member to help you.
2. - Put the airframe aside, pull the components and put them into a new airframe.
Everything you have looks superficially OK, and a new airframe will set you back around $150.00.
If you are not experienced fixing this stuff, you can waste a lot of time and money learning ( not that this is a bad idea in the long run... ).
I approach it from a "am I better off fixing it, or working the hours it would take for me to buy a new airframe" view.
What is your take on that? That may guide your choice.

From the pics, that appears to be a Goldberg Eagle trainer. If you PM me with your e-mail address, I can forward a pdf of the assembly manual, that may help you in repairing and setting up the plane.
