After making a little plastic hut around the tail of the plane it was time to layup the fiberglass. I first ran some tests and let them cure for a day so I didn't screw my large hours on making the mold because I knew it wasn't going to make it two rounds of layup. I used 4 plies of 7781 from Spruce for the layup, the part is quite strong after the fact. I waxed the mold after some more tape work and went to town. I used 4 mil plastic and wet the fiberglass between two layers of the plastic. Then I cut the pieces to size (a little larger than needed) and laid them on the plane. I overlapped in the middle by a few inches, it didn't leave as much of a hump as I thought it would, sanding and micro will take care of it no problem. Finally, I applied the only peel ply I had which was two inch (man I wish I had wider for this one!) The next day I popped the part off, the wax I used worked perfect and let the part go like it was no big deal.

Here it is all laid up. If you look closely you can see a bubble towards the top, it came off the VS about 1/16-1/8", I will fill the back a little and sand it down, no big deal. This was the only spot that it didn't fit perfectly to the fuse.

On a side note, it sure looks ugly at this point. haha

Here is the part after some trimming was done. As you can see I still have to extend the forward parts down and aft a few inches to really close it up. I simply couldn't get the fiberglass to lay down in this area nicely as one large sheet (probably because there was four plies in one?).

Overall I am really happy so far with how the part came out, it may not look like it yet but the contour is pretty dang good! The flat sections in the back came out a little wavy for my liking and I don't think I can use micro alone to fix it so I may have to do some trimming and re-glassing of that area but that's no big deal, it is nice and flat back there; or at least it will be.

It's starting to look like something, long ways to go in finishing it but it's cruising right along.

Let me know what you guys and gals think.

Default Cool beans!

Very nice! We attached the Vans part to the other 7 and like you said the fit was horrible. I wonder if I should just delete the part and save the money on my fuselage order... your looks much better even before sanding. Keep up the good work and thanks for sharing!

Hey Jereme, I suggest you pull a mold off of it after you have completed it.
I would be more than happy to help you do that. That way I can get a better product for my plane!

No problem at all. It will definitely be faster to just chop up the Van's fairing and reglass certain areas if you decide to go that route. However, if you want to learn how to do a bit of fiberglass in the process it seems like a good way of doing it. If you ever have questions just drop me a line!

haha I bet you would! Pulling a mold off of this guy would be a real treat as it is pretty springy at the back when it is not on the plane, it would be tough to get it in the right spot to make a mold.
