Completely stock ParkZone UM T-28 Trojan flying in 12 mph wind, gusts of over 15 mph. Just bought this Monday and have flown about 10 batt. packs before this flight. Love this little bird. Sorry about the camera work it was my girls' first time trying to video anything other than my Blade SR. The sun low in the sky didn't help any either. Some loops and rolls but mostly fighting the wind.
