I replaced it of because my old prop (Ukrainan Aero) is 13 years old and it iis a little damaged. This new has the same power of climb 9m/s solo but in the cruising speed it works on 3600rpm and the old one was 3800rpm. And it is much more quiet. But the date... Is a mistake :) &nbs
Thanks for the feedback Gilles and Joz. Yes scenery is unbelievable. Millions of years of ice, water and wind erosion carving a very rugged terrain. Yes a bit scary. One has to be willing to temporarily give up the "always keep a suitable LZ within glide" mindset in order to fly a trike over the central portions of the park. On the other hand, with greater risk comes potentially greater reward. From what I have been told, there are less than 10 trike pilots that have ever flown the park so that gives some perspective on how many have been willing to take on the additional risk.
