In addition to RotaMax,  the other rotary engine is of course Mazda.    

Many of these engines are flying and thousands of hours have been  

accumulated.  For LSA, the Mazdas are too heavy but they would be good  

matches for any aircraft for which an 0320, O360  or even an I.O. 540  

is the design engine.  The two rotor Mazda can easily produce 240 hp  

normally aspirated, if it is P-ported (peripheral  ported).  Above 160  

hp the Mazda  compares favorably with any recip engine  power to weight.

For the 701/ 601  what is needed is a single rotor version of the  

Mazda and the side housings which are currently made of steel have to  

be made of aluminum to get the weight down to what we need.    The  

good news is that aluminum side housings are available from  Racing  

Beat but expensive.   There are a number of guys working on producing  

aluminum sides and perhaps they will soon produce a less expensive  

version.  Even better,  the next edition of the engine, the RX 16 will  

have stock aluminum sides  from Mazda.  So the future is quite  

promising.



A single rotor p port will easily produce 120 hp and weigh around 130  

lbs.  The engines are nearly bullet proof.  And all the accessory  

packages, intake, injection, drive and so have been around for a long  

time and are reliable.

The website has changed to show pricing of the smaller engines (with PSRU).

However, the less expensive single ignition models are gone. Maybe they 

are still updating the website.
