Sorry, been away from the forum for a bit but the covering on the Sig Primary Force ARF is Sig's own AeroKote - a much better quality covering than the generic Asian knockoffs. Out of the box it was remarkably wrinkle free but the booklet warned it will tend to develop a few wrinkles (it did) when taken out of the box and the wood shrinks as it dries from the humid country of manufacture.

I've still not completely finished mine but should in the next week or so. I've heard it is a terrific flier.

For the most bang for the buck, you can't beat the TF Flite Streak ARF. Put an OS LA 25 or FP 20 on it, balance where it's supposed to be (not where the instructions tell you) and it will easily outfly anything costing twice it's $50 retail price.
