I do not know anything about it but here is a cheaper covering to look into.. Here you have econokote and towerkote I have a strange feeling they are exactly the same product.

http://www3.towerhobbies.com/cgi-bin...=QAATOP&P=7&S= likely this is the "quality heat shrink" mystery wrap your less expensive ARF is covered with.

Just guessing..........................

If you use the search at tower, key oracover (another name for ultra I have been told.) you get econokote. I do not know if that means anything or not. Just something I noticed.
