Hi Steve:

I think that the Turbine ARF's from BVM and Composite-ARF coming out of Thailand are the greatest for those of us who can build but cannot or will not paint....

I think the vacuum sandwich construction in the booms on the KingCat and wings on the Eurosport can be problematic....I fly off grass 98% of the time.....while it is forgiving in many respects, it also can make ground contact in an unusual attitude more damaging as any sharp point like the upper and lower fin or wing tips more prone to dig in, rather than skid like on asphalt....

I don't think the KC boom problem is in the basic design, which is a clone of the BobCat.....I have seen quite a few BC's cartwheeled with no boom fracture, so the problem seems to be one of beef in that area of the aft center section....
