Factory performance figures

[skeptic36]

Hi all,

 

I am wondering how much to trust factory performance figures, are they real and verified or just sales BS.

 

I have been comparing the Quick R with the new Airborne SST and I don't get how although the MTOW is the same (450 Kg), stall speed is the same (64/65Kmh), take off distance is similar (274m Quickr/ 247m SST) the landing distance is 211m for the quickr and 325m for the SST. The other strange one is although the quickr only has 11.43 sq meters of wing area compared to 13.52 for the SST the quickr descent rate is 500ft min while the SST is 770ft min. These figures just don't seem to gel with my understanding of the way things should work.

 

Someone care to educate me, or should I not take notice of factory performance figures?

 

Regards Bill
