Well I sure am glad I stumbled on to this thread. I have two DA 50s, motor # 15 and # 877. Both will die if stopped abrubtly. They are rock solid while taxing and in the air. But if I turn a little fast at the end of runway to avoid going off the end, and the tail swings around or she side hops once or twice on the main gear, your gonna take a hike. The older of the two has over 4 gallons while the other is just finishing gallon number one. I thought it was just me really chranking back on the throttle and getting a little extra travel on the low end of the servo.

Nice to know this is a common problem which means sooner or later someone will figure it out. Has anyone tried a velocity stack??
