RE: Dynaflite Chipmunk - Build
I am not at the level of building where I am doing mods to canopies or anything really complicated, maybe the next build!
I think I will use what came with the kit, it does seem OK, if there is a techniques you could share with me it would be apperciated.
BTW - as an update on the build:
I just (like 10 min ago) put the last piece of fiberglass cloth on the fuse, it looks great. I am using .53 oz Cloth and a finishing resin. This is my second glassing job, the first was a test on a .20 Texan that I have as a static model - this one is turning out better. I have found that I need much less resin than the first time around.
The technique I am using is cutting and laying the cloth out, then mixing a small amount of the finishing resin - this is a much thinner expoy than regular 30 minute, it is a bit easier to sand, and gives a very nice glossy finish. I used a small foam brush and a plastic key card from a hotel. I will drip a bit of expoy in the middle of the cloth, then work it out from the middle with the key card. The card is perfect, it is thin and easy to use, while being flexible enough to fit the form of the fuse. You would be amaized how little resin you need if you use the card in this manner. I use the foam brush in some places if I need a little dab of resin to make it stick.
After getting the cloth as flat as possible - there are always a couple of little bumps and ridges to sand off - I use a roll of regular toilet paper to get the execess resin off the plane - again there is usually not much because I am using as little as possible.
The thin resin sets up over night and I can lightly sand down the fuse the next day. I have spend maybe 6 hours on fiberglassing this holiday, that includes the light sanding.
Once the first coat is set and fully cured, I will do a full light sanding with fine and very fine paper (600 grain), then lay a second light coat of resin to seal everything up. Waiting a few days to let the epoxy cure, then a detailed sanding of the fuse. I will check for any problem spots I missed the first time around and fill them in with glazing putty (bondo) again using the key card as it is a perfect applicator. I will then resand the trouble spots and prime the fuse for painting, look for problem areas again, bondo, sand, final prime and paint.
Once that is all done, I will work on some cockpit detail, then start covering the wing with cloth.
I am beginning to think that this project may actually be finished by the end or the Winter!
Hopefully by the end of January I will have the plane ready to install the radio, motor and electronics!
I would post photos, but there is not that much to see rigth now, the fuse looks almost the same, just a bit shinier because of the glass. The Wing is also about the same, all I have added is some the servo wiring. When I start to paint I will take a few more pics.
