          fitting brand new Renesis engines ( RX8) They are aiming for reliable,
          economical 165 HP.

                    Not quite there yet but getting closer. I am building the Arrow and have

          a site on their web www.tomair.com.au under discussion boards then builders
          forum.

               What are they using for a PSRU Baz? IMHO the Renesis is reliable at 240

          HP.

               If you want economy you can always throttle back.

          Baz,
          How much was the kit Baz - I spoke to the chap at Cobra and he didn't know
          that much about Mazda's when I spoke to him. The last I heard he was working
          with Leon in Sydney

          Advice to me was he was someone who needs to be watched as he hasn't been in
          the aircraft building game for long.
          Who knows how or where that comes from, perhaps professional jealousy.

     Oh oh we are in trouble now :) You and I George are among the few people on here
     that have actually met Leon.

Here is an email I got from the designer:

Hi Hans

Thanks for the info
I am still having a little trouble with the site as far as the FAQ'S seems some little smart kid in the USA crashed the server and they had thousands of site with problems I have tried to rectify it but will need to have another go at , as for the forums you will need to register to get in I have only had one guy who had some problems logging into the forum and once he registered all was ok it could be because the forum uses php format ,

but as far as the kit costs it sells here at $42,850.00 aud you would need to subtract 10% as tax is not applic if exported , the freight costs vary we have found it easier to arrange freight from the USA rather than here , it will fit into a 20" container easily even maybe get 2 inside .
As for the rotary engine well its a bloody ripper Aussie slang for very good , we have the mounts, cooling system, exhaust, new manifold, our own re-drive, our own constant speed prop , the engine will produce 237 shaft hp at 6000 rpm this equates to 165 at the prop flange it also burns at full continuous power 27 litres of fuel phr or in cruise mode around 22 litres , all our engines are new ex factory non salvaged engines directly from Japan we still strip and check every engine they are given an ID for trace ability and are dyno run with performance sheets supplied , I will be looking to fly the first 2 of our rotary powered aircraft within the next 4 weeks so this will be a very exciting time for me , the calculated speed of the aircraft should be around 205 knots so it will be very interesting to see the outcome .

At this point we do not have any agents in the USA although we hope to start on the US market very soon

Thanks for your enquiry Regards Tommy

"237 HP at 6000 RPM equates to 165 at the prop flange"?  "27 liters (7GPH) per hour at full
power"?  This guy is an idiot or an out and out liar. Sounds like a scam. I would not 
give him any of my money. "295 Kts (236 MPH)"?  Why is it that rotaries attract the charlatans?
It just seems like so many of them are Aussies. Must be left over genes from prison colony
days :) Either that or they think Americans are stupid.

Good luck Baz.
