Last Mazda Rotary thing I saw ended up in a crumpled mess in the trees at YCAB .
Now I truly wish them lots of success, but I am not that brave!
Good point HH.....

There is an outfit called Rotaryae who have / had some very promising rotary aircraft engines for the experimental / LSA market, but there are not open for business just now. I had been talking to them for some time, but the latest I got back was they had lost a lot of backing after the $meltdown. They are using licenced Mazda tip seals and and a total loss oil system.
That oil system was a major sticking point with the 'greenies' apparently but over a 50 hour cycle the oil use was less than half if you consider having to dump the old oil on change etc. Also no filter or cooler required. I thought that rather neat. Add to that a 3000 TBO and a 4 man hour strip down / rebuild and you have a promising engine...
A pity since they could deliver 125HP normally aspirated twin rotor units for the same weight as a Rotax 912 (inc PSRU) for half the price. Or a Turbo version for a little more weight and a good deal more poke. Very nice specs - I can only hope they get going again. The web site no longer has the blurb, but I do have a copy and here it is as of 6-9 months ago :

You can't put a Jap engine in a Mustang
I hear the NZHN one has 190 HP up front using the Mazda Renesis engine.

Well the T51 serial 70 flew on the 9th March 2010. After 4 years building she flew very nicely. The CSU didn't - so speed was restricted by RPM, but that is a simple fix. The first flight was a gear down, couple of circuits anyway. No handling issues, no cooling issues - nothing fell off What more can you ask for ?
25 hours of flight testing / proving ahead for certification and she is done. I am looking forward to the flight testing as I am very keen to get some solid performance numbers on this (basic) T51 powerplant setup and see if our 'clean' airframe will give us a performance improvement relative to the amount of extra work involved. I doubt it - but she sure looks nice.
If the next few flights prove the cooling system is sound - it is a novel approach with both radiators up front in a 'managed flow' scoop - then we will not need to make any mods to the cowl openings and that final bit can have some paint.
So that is the end of the build phase, 4 years / 4500 man hours aghhhhh. Hopefully we can now get down to some flying...
Now about that 1/2 scale Mosquito
Movie at VIMEO.COM - search for T51 Mustang Ardmore. I have only just uploaded it, so I don't know what the quality is like. I will replace it on the same tags if it is a dud.
Unfortunately I was not there to see the first flight as I am up to my armpits doing the test acceptance on a new 777-300 CAE 7000 Sim. Never mind I will get my hands on it this weekend....

Hey folks,
No one has mentioned Gilles Kupfer's Focke Wulf Fw190D-9 replica. Utilising the legendary M14P 9cyl Radial. This thing is unbelievable. Was over at Wanaka doing a bit of flying over the last few days and had a good looksey and a yarn with him. It will be on static display this Easter at the airshow and he will be selling kits from next year. This is by far the best replica I have ever seen. It looks right, and it flies right, and it sounds right!

T51 #70 has finally flown properly.
The old adage that a build is always 95% complete and only 95% to go is almost certainly true. After her first flight last year I had to ground her for months while we sorted out issues with fuel leaks and many minor niggles. After 7 hours of flight testing the prop proved troublesome and had to have new blade bearings. But that is all behind us now. (I hope).
The final basic weight was 951lbs and she is effectively a single seat microlight unless you are thin and your passenger is anorexic. However a single seat at 1200lbs MAUW is a good place for this one as the performance is rather nice there. At 1450 she would be a bit of a slug and 1850lbs doesn't bear thinking about.
I have done all the testing myself and she flies remarkably well for 100HP. Very responsive and light on the controls. Not the fastest thing I have ever flown, but she certainly is slick for 100HP. Sitting in the big bubble is the nearest thing to being on the 'Magic Carpet' I have come across yet in 45 years of aviation.

I have the drag polars worked out for this airframe at 1200lbs and the HP/IAS figures are interesting. - the basic table is below although I am not sure if the formatting will come out well off of excel....

Mosquito replica
I have it on good authority that Terry Kronk's Mustang replica is nearly ready for its first flight, and the scale Mosquito is well underway at his hidden Emu Works facility.....

The airtesting on our T51 is now completed and she flies just fine.

JS and co have put a lot of time into their Renesis powered T-51. There were a lot of engineering challenges to overcome and I believe they are still working on a few niggles.
I was fortunate enough to be out at the airport last weekend and saw JS flying it around the circuit. It doesn't sound like a mustang, but it sure goes like one! They did an excellent job of the finish too, it looks stunning. Wish I had my camera with me at the time but I had left it at home.
