Eric, I wouldn't do that. You would only be adding unnecessary weight. Do it if it needs it in the event of a crash, even then it would only be needed 1"-2" beyond the break. This plane flies extremely well but it can be very twitchy. I fly the older plastic mount version and not the newer beam mounted. Ken

I've done it on some and not on others, but never had one break at that joint. I've broken them in plenty of other places. I usually use epoxy there.

Speaking of fiberglass, can y'all tell me what is the weight of the light glass cloth that used to come in Goldberg kits? And where can I get it? I haven't been able to find it.

Eric,

I would glass the splits at the LE/TE. It's cheap insurance without adding much weight.

Rusty, if you haven't split a wing down the middle you are not trying hard enough!

Rusty, Hangar 9 offers .5 oz. cloth which is what I use a lot of. I cover the entire fuse with it using Polycrilic. I give the fuse one coat of poly after the cloth is applied and then I use lacquer primer to fill up the weave. This stuff is light and works well for essentially any repair. Ken

I never realized there was cloth that light, because I've never used it in modelling or paid attention to the weight of the cloth that other people were using. I just weighed a same-size (1 sq. yd.) piece that I have on hand.. and it weighs 5.85oz. I guess that's be more for a full-scale repair job.

I've made fiberglass window screening patches and brushed epoxy through them, to strengthen certain areas. I tack it in place at the corners using thin CA first, to hold it in place while the epoxy sets.

Thanks Ken, now I can get some. I've been using too heavy a grade of fiberglass because I didn't know where to find it.
