Good for you for fixing this, I have a friend that has rebuilt a favorite Pitts of his so many times I am not sure if anything but parts of the tail are from the original plane... He finally put it in so hard there was no chance to rebuild.. But it had MANY lives It took one of the younger members of the club a couple minutes to pull the motor out of the field ! One of those crashes where the back of the firewall was below ground.

hope it goes well.
