Hmm, Im not sure what brand of covering they use. But it is a really nice covering job. Both of the ones I know of that are in service are not new but seem to be holding up very well to exposure to fuel and the elements.. I really think for that size its as good as any for that price for an ARF.
The Zens are even better but they are quite a bit more pricey. There are lots of options for 90 size pattern planes, do your homework and you will make the right choice. [8D]
My main thing based on personal experience would be to NOT put a .91 on the Venus, either run a smaller engine or move up to a bigger plane. Ultimately you will make the best decision though.
I agree Kyoshos covering isnt the best, I bought a Flip 3D and brought it back. The woodwork was nice but the covering sucked. Too thin IMO.
