what carbon fiber re-inforcing? i am considering getting one of these as i was very unhapy with my other foamy, and i flew one of these and it was like magic. i could do rolling "circles" that were a single roll per revolution with so tight a radius that if it were not rolling, it could have been bolted at the wingtip. it was so cool! would anyone be willing to trade one of these for an almost new himax 2015-4100 plus a few bucks?
