Hey Mike, no problem!

Magne,

My fuselage failed on it's third flight. I had at this point only flown the model in very soft trimming flights. After landing on the third flight I noticed a vertical crease on the right hand side (viewed from rear) around 4" (100mm) in front of the fin base former, there were no unusual sounds from the plane as it was being flown ie: flutter noise or similar.

I have repaired the fuselage with 4" glass cloth all the way around the inside of the fuselage at the failure point and then I have installed a horizontal 3/8" square balsa ladder from the wing dowels to the finbase former. I have also installed a 45 degree former from the finbase former rear, to the rudder stern post (notched in). I have removed the false hollow leading edge on the original rudder and replaced it with a balsa bevel edge. I have also installed 5 Robart hinge pins
instead of 4. I decided to change the latter because I felt that far too much play at the hinge points could be an issue.

Since carrying out the changes to my Impact, I have had many flights all of which included snaps and spins and so far so good.

The model is YS 140 powered.

Regards,

Andy.
