Thats fair. First off at our altitude of 5000ft engine performance suffers greatly. I have been at this 5 years. Every plane I own (8) has been ARFed from others success or failures. There is nothing worse than a nice plane but underpowered and therefore given a bad rep.
* Now some may consider mine an over kill but if it flys the plane well, so what. I make modifications as neceeesary. Usually in the strengthening area. My Wm Midget holds an OS1.08. A .40 size P51 with a G90. Cermark F20 with a Jett .90 and so on and they fly great. I have seen these Hangar P51's here. Very nice plane. 2 with Saito 100s and the other a OS91fx. All flew very well. I just want more.
