Here I am sitting reading ALL this info on engines most of which is pure cunjecture and terminology.............which engine "RIPS" which prop.........rpm figures with no mention of prop type or exhaust system......."unloading in the air"........."overpropping" "underpropping"............its ALL phewey!!

Solution.............all manufactures should be bold enough to put in every engine box they ship a graph of POWER VS RPM and TORQUE VS RPM TESTED ON A DYNO WITH OPEN EXHAUST.

No-one is telling me they dont have those graphs avaiable.
Lets see................Zenoah do it.......!!

How about it?
