Well I hope everyone understands that I'm not blaming anyone for this but myself, I'm never quite sure how jokes will go through here, but I thought it was a funny twist to blame it something else rather than myself.
The real reason was poor a pre-flight check, as I took of if only one or two rubber bands, I'm not even sure about how many there were. I had had a poor contact with the aileron servo and was taking the wing on and off. Wasn't really meant to take off like that but with a poor short-time memory I simply forgot all about the wing attachment. It wasn't until I was in the air that I realized something was wrong and on the downwind leg when going in for a landing the wing broke loose and the fuse went on its own spiralling down...
Anyway, I'm not too sorry about that. After a reparing and a few mods the plane now weights about 27 oz (rather than 30 oz) and it now also has a rudder for a bit safer take-offs...
