Bob,
I would have used the OS, but I had the YS laying around and I sold the OS with last year's Insight. So far the 140sport has been great. I was thinking of going really simple with a 160fx later in a backup INSIGHT (see images).
As for the flight, it flew like a feather...with a 140sport attached! We got two flights in fairly windy conditions, so I will certainly have some more trim flying to do. Takeoff was at half throttle and left Mother Earth as nicely as a Partner. The downlines were straight down for 200+ feet, then only a very slight pull to the canopy. Knife edge required a slight opposite aileron mix, as well as a few % mix of up elevator (barely tucks to the belly). With the mix, (2nd flight) it went very straight in knife with rudder input only. Uplines were very straight with no rudder input...so I guess the right thrust is about right. Rudder is very effective. Stall turns are almost like cheating. It will take some getting used to because my tendency is to feed in rudder input early in a rolling element.
The most interesting thing is how slow this bird will fly. Downlines are slow (but not electric slow) and the bottom radius exits immediately cause a deceleration that has to be seen to be believed....the exits are just amazing. I must inform you though, I am running a 17x8apc, but at this weight, the prop seems perfect. Had plenty of guts going over the top radii, even in today's windy conditions.
Don Ramsey took a turn at flying it and even he was smiling.
Regards,
Mark
