That Mr. Atkins is quite a rotary salesman! In regards to his comments about the Renesis, keep in mind that he has perhaps the largest collection of earlier 13B parts in the world and he would like to sell them.

I assume he was talking about 2 stroke oil in his 1qt per 5 hr. story. I use about 1 quart in 8 hours (the Renesis needs less oil in premix than the earlier 13B) and if that stops you in your tracks, you should definitely forget about the rotary. I've never had to add crankcase oil between changes at 50 - 60 hours. I have over 500 hours on the Renesis and it's still runs like new. Compression is still at maximum. Fuel economy is not much different, maybe 2 - 3% better than the older engines. I burn 6.5 GPH at 172 mph TAS at 15,500.

I don't sell engines either.

For anyone hoping that a 16X would show up any time soon: not ... gonna ... happen. No RX7 and the RX8 is still powered by the Renesis for 2011.

As if that's not bad enough, when I was at Oshkosh I took in David Atkins rotary seminar. I came away pretty depressed thinking that I probably won't put a rotary engine in my airplane. Is everyone else really using 1 quart of oil every 5 hours? He also didn't have much good to say about the Renesis in an aviation application which leads me to conclude that the 16X will fare even worse in aviation applications as it is tweaked to meet higher EPA requirements and produce more low end torque.

Is anyone but Tracy using a Renesis? I'd really like to know what HP you're getting, what the fuel burn is and how it's holding up.

Thanks,

Dwayne

P.S. I couldn't find any rotary planes on the field at Oshkosh. Perhaps they sank into the mud.
