I’ve had to do quite a few repairs to planes, my most recent damaged plane was the Blackbird which I flew into a tree, should be a good place for a Blackbird to be, but apparently not. Since the plane is so simple with not too many bits I was thinking of taking the electronics and building another, but our illustrious and wise chairman, Mike, made comment that it could be fixed, and when I got home and inspected the damage it became clear that he is indeed wise!
So the main 3 areas of damage were:
The nose had been snapped, this glued back together nicely, no problems there.
The forward left of where the nose becomes the body had a big chunk snapped out of it, I did have the bits that had been broken out, but some was missing and what I did have had been distorted so didn’t fit back very well to glue back. So a replacement bit needed to be made. I used the opposite side to make a piece which would be the right shape, then flipped it oven and put it over the hole and cut round it to create the gap for the new bit. Some UHU Por round all edges and let it dry for a couple of mins before putting it into place, and voila:
The other section of damage was the tail. This had quite a large chunk off the back of it, and I did not have the various remains. So I decided to replace this also. Using the original plans I created the replacement tail section and then again used this to cut the old damaged tail from the model. My next concern was that the stresses on the tail would be too much for just a bead of glue down 1 surface to hold. I did have some 2mm fibre glass rods, so decided to embed 2 small bits of this to give the tail more strength without adding too much weight.
IIf i hold the tail up to the light you can see them through it:
So finally there are a few little nicks in the body which are not serious enough to replace sections of the body, but look a bit odd, so a bit of black tape over these should do the trick. Sorry Scott, this is actually packing tape, not gaffa tape, but I may have to revert to gaffa tape if these don’t stay stuck.
So now it is all back together.. A bit of a black-and-white-bird now, but that will just help me tell which way up it is…
We shall see if it still flies as well as it did
