Hi all,
i am 15, and am currently working on building a plane, and I have come to the conclusion that the Wankel is the best engine solution.

I am going to use the 13B, as it is the best bang for buck. i know that the rotaries can be tuned up to absurd performance numbers; but due to the fact that this s an aircraft application, i want a well performing, very reliable engine. i realize that Wankels require excessive amounts of TLC, but i am fine with that, it just makes it more interesting. i am wondering what is a reasonable expectation for a 1991 13B turbo. as i mentioned, i am looking for reliability above all, so i was thinking around 500bhp. another point to mention is that i will be cruising for extended period of time (3-4hrs) at very high RPM's (4.5k or higher). also, torque has priority over horsepower, because if i have more torque, then i can turn a bigger, more efficient propeller.

i looked into getting myself a 20B for this project, but they are so expensive that because i need 2 of them (a twin engined plane), it is just not worth it (as budget friendly as possible). i am going to get my engines from this site: </title> <meta name="robots" content="index, follow" /> <meta name="GOOGLEBOT" content="INDEX, FOLLOW" /> <link type="text/css" href="//ajax.googleapis.com/ajax/libs/jqueryui/1.8.4/themes/base/jquery-ui.css" rel="stylesheet" /> <link type="text/css" . i have looked into rebuilding an ebay engine (mechanical things don't intimidate me...), but i do not trust myself for such a critical application. if there is another way to get a similarly rebuilt engine for less money, then i am open, as my budget is not particularly large. or if you just have other rotary related tips, then let me know, as i am pretty new to the rotary community.

thanks,
Christian L.
