That was built by Ewald Schuster (pegasus is his RCU name) a few years back. He scratch built the entire project. Had the airframe ready to go and had done conventional take off and landing tests. Last I heard he was getting way to much RFI from the fan to fly it. He had bedsteaded it though. That was with 72Mhz, now with 2.4 perhaps he should not have the RFI issues. He has also built a whole bunch of really great stuff that he has on his website. Amazing guy. Scotty
