With the improved in the quality in the foam used by GWS.. is there a "real" need to glass the plane ?

Thanks

Glassing serves two purposes - strength and making a nice surface. The newer models are significantly stronger than the older ones especially around the wing saddle. And the new model's foam has tighter cells making a smoother surface. So I guess there is no "need" to glass anymore, but folks will to make a superior model. I'll still be top coating mine with a WPBU spray to harden the surface against incidental hanger rash. And I may try to prep the surface with a WPBU and talc mixture to fill in any foam pores.

I've never glassed any of my GWS models, nor ever felt the need to, but I buy Jim's point about coatings to reduct hangar rash and since Molders drew my attention to it I've been using Johnsons Klear which is a "brush on" polycrylic floor wax, sold in the US as "Future" and I find that works very well. Puts on a pretty hard satin finish but adds little weight. I find that two coats work best one before decals and if you're using pastels or any other "weathering" medium before that too and then a final coat to seal everything up. I haven't tried it as a"fixer" for inkjet printed decals but it might work there also. Little article about it here http://armorama.co.uk/modules.php?op...icle&artid=227

Thanks! Another technique. I Googled "Future Floor Wax" and found several articles form modelers on the stuff. I now have a burning desire to go to the store and try it out.

Thanks for your reply James and Roger.

Well, I managed to get hold of minwax. Tried it on some light fabric cloth ( Organza ) . It sticks really well. However, the fabric does not seem to add much strength.

I have to get some FG then.

Good luck to me

Thanks again !

Glassing..


The one down side to the GWS foam planes is that they are very easy to dent. These dents accumulate to make a rather shabby looking plane.

My E-starter is only a few weeks old, but the foam around the battery tray is pretty ugly. Even with a coating of water based clear coat.

The other issue with them is cleaning.. I fly off a grass field, and the grass will make a lovely mess of the bare foam.

So with these issues in mind, I have been debating the glassing process on my 190. I expect to have the plane for a long time, so why not spend a little more time to make her nicer?

My current thought is to only glass the bottom of the wing and fuse and a bit around the battery hatch, and just clear coat the rest. I picked up the lightest weight glass at the LHS, but it is 2 oz.. So don't want to glass the whole thing with this.

GWS glue..

On another subject. I have used nothing but the GWS glue on this build. I am having issues with very slow cure times! I used it as a contact glue when joining the wings. It grabbed pretty well when I first touched them together, but even after 3 days it still dribbles fresh glue out of the joint. It is finally strong though.

I also used the glue for the spar. I highly recommend you use an epoxy for this joint. Talking to another builder that also used the GWS glue on the spar he reports the same issues. It will not cure, and keeps puking out more glue from the ends of the tubes, center section, and sometimes middle of the wing. I did not think I put too much glue in either! (I also do not recommend Sumo or Gorilla for the spars as the foaming tends to make an ugly joint that can be tough to clean up.)

The GWS glue seems to work best on smaller joints.

I do like the GWS glue, but I have learned a little more about its use.

2oz. is pretty heavy. I would have your LHS special order some .75oz or go online and order some. I glass the majoirity of my planes, for the finish and durability. With practice, you can get your planes to come in at weight most of the time. Or just go down in battery size. I think the trade-off is worth it.

Wayne,

GWS glue is a contact cement. In order for it to set up properly, you need to apply glue to the surface, and let it air dry for about 5-10 minutes. What I typically do is put a generous amount of glue on one side, press the parts together briefly, then set them aside for 10 minutes. Once the glue feels "tacky", it's ready to go. A word of caution, you only get one shot to line the parts up correctly. If you can still move the parts around after assembly, then you need to pull them apart and let the glue set up a few more minutes.

I use GWS glue as much as possible. It's free (comes with the kit), and I have several tubes lying around (I only open a new tube when I finish one off, so I have several tubes from my many GWS kits). I generally only use epoxy on the spars and control horns.

Oh, and as The Bandit said, 2oz cloth is way too heavy. Try finding some in the .5 - .75oz range.
