while flying at then inlaws today I lost the Mini Force to slack lines and a puff of wind on a wingover today.  Full speed with a 5x3.5 MA on 45' lines nosed in.  Fuse turned to toothpicks from the trailing edge to the stabilizer.  Not sure but looks like the engine housing around the venturi cracked (dangit!!!).  Wing sounds like a maracca, splinters coming through the covering.  Was able to salvage the stabilizer and elevator, can't believe they made it as they were "stick built" and covered.  Plane is a lost cause, time to start another.

Remember---a picture is worth a thousand words!

THANKS BILL!!!  I was wondering if good ole JB would help me out on this, gues I'll find out for certain

Bill is correct, I've repaired two Norvels with cracked cases, just clean it really well with alcohol and layer some on.  It's been holding a crack down the venturi for 2 or 3 years now, hasn't spread, also holding a venturi insert in on another.
