Do you have any of the missing parts? Even if damaged hey can serve as a pattern for new. If you have the firewall that would go a LONG ways to getting on the right track.
The CAP in my avatar started life as a H9 ARF. It, not me
crashed due to the horizontal stab not wanting to play with the rest of the plane
At first glance I thought a new wing would fix most of the damage along with said stab repair. WRONG! The fuse doublers had mostly broken loose from the balsa sheet and the light ply formers were heavily damaged. I wound up scratch building a whole new plane. I did save the canopy, cowl, turtle deck behind the canopy and the rudder and elevator. I used the parts and pieces as patterns for new parts. Some would say it should have been trashed and they are right. I took the challenge and have a pretty nice plane.
Good luck on your rebuild. Keep us posted on the progress!
