White glue is a problem over time...no laughs now but my OLY 750 ( a 650 with an extra 4 wing bays added, kevlar wrapped spars , etc..) self destructed this spring after only 24 years of flying..the white glue in the fuselage joints crystallized and it came apart on launch...yeah I know...BO Hoo ...but I will rebuild it this winter...just beware of white glue like Elmers in the long haul...actually I did not build it...got it in a TMSS swap meeting in Virginia in 1992...never checked inside...flew it a lot and recovered it once in 1995 and again in 2010...it was my go to plane each spring..
