Does RPM = Power?
Hi,
I am a new owner of a 914 powered motorglider and I am a bit concerned about my engine power. My engine can sustain 5.800RPM for take off, but my question is, does this 5.800 RPM ensure the 115HP, or it's possible that it's delivering less horse power?
The reason for asking is that Saturday it felt very uncomfortable to take off at my home airfield - EBSH. It was 15C and the runway was the 05 (grass, humid but not soaked wet, 561m/1839ft and 3.8% slope). We were 45Kg above Maximum Weight. But, even in the air, the climb rate felt very sluggish... :(
If the 914 can reach 5.800RPMs but not deliver 115HP which are the most probable causes?
I am based in Belgium. If you know a good Rotax mechanic who does a good job at reasonable prices please give me their contact. I can fly a reasonable distance.
I am in love with my motorglider, but having this trust issues is not acceptable for me.
Thanks for your help,
Joaquim Fonseca
