Welp, I guess that all planes with a wing that's larger than a piece of balsa are gonna break.

Okay, I glassed the offending sheeting joint with 6 oz cloth and 30 minute epoxy. I cut the
wing in half and there is one layer of 6 oz in the middle, so far. I'll do a second.

I'll glass the entire plane with .75 oz cloth.

It'll have two OS .10 LA engines. I wish I could find more powerful .10's. Any ideas?

Thanks for the advice on the wing. I know that all are trying only to help me. I appreciate it!
Mike
