Sir,

 I may be missing something here,
 If the maximum propeller rpm is 2800 .
 A single rotor engine with max rpm of 1100 with 37 KW @  8750 rpm.
 With a reduction drive of 3:1 one could achieve maximum propeller rpm of 2800.

 Why can't this engine with low HP but with high rpm be used on the Parsons auto gyro ( on YouTube https://youtu.be/QOwb8QRHrMY )which is currently using the 12a Mazda rotary or can it ?

 Best Regards
 Zahid


 37 KW is only 50 HP. A Mazda 12A 2 rotor makes at least 150 HP.
 Gyro's, like everything else fly on HP. It probabbly takes a minimum
 of 110 HP to fly a man powered gyro.

 is using the AIXRO XF40.
 I know you are familiar with this company. How is that possible ?

Some super ultralights aircraft will fly on 50 HP.
Not gyro's. There is a lot more drag on a gyro.
