poz Posted April 19, 2017 Share Posted April 19, 2017 For the past couple of years I have flown a Pap Thor 250 under a 27m Niviuk Link, clocking up a couple hundred hours. Here are the numbers: Cruise rpm: 4800. Consumption 2.8 lph Speed (trims out) 28mph Me: 85kg (bare arsed) Machine (44kg with 6 litres) However, I recently got a new wing, well the same wing but in a 23m version which in reality is considerably less fabric. Cruise rpm: 4500. Consumption 2.3 lph Speed (trims out) 31mph Me: 86kg (bare arsed) I've put on a kilo recently Machine (44kg with 6 litres) Smaller wing much easier to launch and land. Very surprised with these numbers, I guess it's about parasitic and induced drag. Not sure which is more responsible for the better performance, but I have a feeling I'm going to be enlightened Quote Link to comment Share on other sites More sharing options...
