RE: Icepoint Wing Failure
I agree the Ultra-RC did the stand up thing and ponied up a new airframe. I personally think that the updated version should have a solid foam core wing, it may ad a little weight but the strength gained will be well worth that slight gain.
But I still find the glue joints that I see on the newer "high quality" ARF's to be a little suspect. I suspect that they go light on the glue to save weight and to reduce production costs.
I am of the opinion that if you sell it as almost ready to fly you shouldn't have to spend the extra time re-engineering it to make it durable, If you spend two or three extra days going over it before assembling it, it shouldn't be advertised as high quality.
