A strange RC model crashes at Tokoroa airfield

I thought I'd try out the cheap telephoto lens I bought from China on my Sony 760 video camera and caught this little bit of action from the other end of the airfield.
Seems this model has some definite stability issues.
Unfortunately, the lens is crap. A lack of decent achromatic coatings means there's significant color fringing and the image is quite "foggy". Still, it only cost $10 and now I can use it for burning ants in the sunlight ;-)
Poor Ron.
