Jon, Hope it's been enough time to ask how this is coming along without bugging you So, how's it going on the open twin/defiant plans ? Thanks, Randy

I am not finding a Defiant listed. Could you post the link please. Thanks

I think this information would certainly end the SPECULATION that this engine is nothing more than a line drawing. As for Zeitlin I guess "His exalted all knowingest" would be a more appropriate preamble as he openly espoused that this engine would ever fly.

Attention Rotomax haters, Here ya go ......http://www.contactmagazine.com/backissu.html#current I hope Herr Zeitlin takes note as well. Cheers, Randy

I'm not sure if this is big news or not but it looks like the Bateleur will be coming to America soon. According to their U.S. site www.rmtaviation.com they will be selling complete kits to include the Rotax 912 ULS engine and also a fixed gear fixed prop LSA version. They seem to infer that they intend to also sell an all up ready to fly part 23 airframe as well. Looks like they are planning to open shop at a small airfield in Northern California and if they can get their demo aircraft in time from South Africa be on display at the Reno Air Races. No price info that I could see. Having been a huge fan of this airframe and engine combo for some time and am glad to see that it appears to be moving forward.

Herr Zeitlin, Your terms are acceptable to me. Please excuse my tardiness in replying to your offer as I am currently in Beijing China and have a rather slow connection. Please see my attached photos below : I took these photos a little over a week ago while doing some gyro copter flying in Utah. I have held this engine (w/o the crank in it) in my arms and would estimate it in that state to weigh in the neighborhood of 110-120 Lbs. All up in it's non-turbo-ed version it would weigh around 155 Lbs. I have also attached a photo of it's smaller 75 HP sibling. Currently this engine is FLYING (you are familiar with that term, are you not ?) in two gyro copters in Ohio and is installed on a few LSA fixed wing platforms for the purpose of building hours to gain ASTM certification for use on both E-LSA and S-LSA aircraft. Feel free to call AirGyro Aviation at 801-794-3434 and ask to speak with Nate. He will "illuminate" you further. As for our wager please proceed to Hangar G just off Commercial way on your airfield there in lovely KTSP. There you can make the acquaintance of my business partner Mr. Bob West. Bob is a retired Mechanical Engineer from your alma mater. He spent several years working at Porsche developing engines for their formula one racers. Bob is there just about every day. Currently he is busy finalizing a panel for my float plane. He will be happy to help educate your rather lacking knowledge of the Wankel style rotary engines and their value both in racing and aviation applications. I appreciate that you would allow me five years for the outcome of this wager but I really feel we shall see it reach fruition much sooner. Being a Zymurgist myself I will say I am a bit puzzled by your choice of libation. While Guinness is a fine example of a mass produced dry Irish Stout even the Irish themselves much prefer Beamish (though it is rarely found outside of the Emerald Isle). What with your German heritage I really thought you would have chosen a higher quality beer such as one of the "Fest Bier" varieties of the Pauliner family or perhaps a Spaten Optimator. JMHO "Most" Sincerely, Randy

Here is the engine that this design desperately needs http://www.rotamax.net/downloads.html . the 180hp turbo version it would truly be a force to be reckoned with. BTW this engine is the future of GA. Yes I know that rotaries burn more gas but the reliability would be thru the roof what with only three moving parts, overhaul would be on the order of maybe $400.00 if that. We will be seeing a lot more of this engine.

I don't understand, I show that the Cozy is 42 inches wide across the front portion of the cabin. That breaks down to 21 inches per front seat occupant in my mind. Give me the elbow room of a tandem any day even if its a J-3 Cub.

Thanks for finding the pics Brett. Very inspirational. I am toying with a similar idea only using a long eze sized fuselage and twin rotax turbos. If Piaggio can pull this idea off with their Avanti I don't see why it can't be done on a smaller scale. I think the guy who tried it with the twin eze before went wrong because he did not have the central rudder. Fuel would be kept in the wings as always. Cheers, R.P.
