Guys,
When I was first learning to fly 4 channel, I crashed my E-Starter so many times that I wasn't sure I got all the pieces back together straight. However after a while, I was actually flying it. I decided to give it a cosmetic make over and did the same paint thing on the fuse. As I was watching the foam melt I decided I was going to save as much as I could. I immediatly grabbed a knife and started scraping away as much of the melted foam as I could and then actually cut into the nose, until I found solid foam. As you can imagine, a lot of foam was missing. I was actually going to try a carve up a new piece of foam and glue it in, but I guy turned me on to the Gorilla GLue/ Elmers technique. Since I had nothing to lose, I secured the stick mount where I thought it should be. them formed a sortta cup affair from packing tape. I poured in the mixture into the cup and waited. It started foaming within minutes. I left it sit over night and when I came back in the morning, found a huge ball of newly formed foam where the nose used to be. a little carving with a Dremel Tool, knife, and sandpaper and I had the profile looking as good as new. I little light weight filler to fill the air holes and a dab of white latex paint, and it was hard to tell it had ever been crashed.
I have since experimented with the Gorilla Glue/Elmers mixture and found it to be exellent for repairing all sorts of things on foam planes. I broke about an inch off the wing tips of my E-Flight P-47 and just put some wide masking tape on the bottom of the wing, spread some of the misture on the edge of the wing, and like magic, there was foam there, in the morning where there was none the night before. Shape it and sand it down, a little paint, and it's a good as new. I also broke 1 1/2 inches of the top ot the tail, and just "grew " a new one, using the same method.
I have since stopped using epoxy on any of my foamies. The reason being that epoxy adds so much weight, and unless you pour it on, doesn't fill in the voids where foam was lost. The mixture is super strong and adds no weight, and fills in all the voids where there was lost foam.....
It does take some experimenting to know how much to use as the amount it expands is quite substantial. But it works great..........JMHO...Pat
LOL....good info!!!! ARROW....pay attention, this guy is all over it.
