The aircraft shown is only newly flown, so I hadnt caught up with it. Dave Comrie had a rego ZK-FWS reserved for his machine (fast walking stick he said) which is different to this one, but that doesnt necessarily mean much. Looks nice though - at least the cowls look closer to the real thing than most Sindlingers.
If it was supposed to be easy. everyone would be doing it...
Unfortunately Dave is still not around, I met him a few times as he knew my father. I work at Taieri Airfield, and yes the aircraft ZK-VYX pictured above is the one Dave started. In fact, the current owner completed alot of it in our company hangar. The reason the cowls look much better is that it doesnt have a boxer engine but a 3L V6 in it. It sounds very much like a warbird with the short exhaust pipes. It did fly after dave finished it, but not very well according to John Penno the test pilot. It has now had extensive changes and is apparently a very nice machine. Hope that helps I have shown this thread to Bob, the current owner and I'm sure he could shed more light than me on the subject.
Dave's Sindlinger is alive and well and owned by me. It is now ZK-VYX and is based at Taieri. It is now powered by a Mitsubishi 3Lt V6 and is nearing the end of its endurance testing. Still working on a more suitable prop as the WarpDrive HP blades don't seem to absorb all the power It will be part of the Museum display at Warbirds this year. Stalls 35knts Vne 200knts
