After few hours of simulator sessions in various fly modes I'm trying to become familiar with real Inspire 1 Pro response to stick movements before maiden trip ... I've anchored legs to 4 bricks (using cable ties), set everything on a table and prepared for manual take-off. I assumed - perhaps wrongly - that the entire system is able to perform manual take-off. CSC command worked as expected and I start moving throttle stick very, very slowly up. And it scared me to death, because props start rotating full throttle almost immediately after passing a certain point, very close to the beginning of the movement. It was like the machine is trying to take rapidly off despite my intent to do it manually in gentle manner. Bricks did the job, but anything else on the table was blown away before panic CSC ... Before this one only and unsuccessful attempt to start the machine, I did the same with no props attached just to explore Gain & Expo Tuning feature in DJI Go. There I've discovered insignificant - if any at all - results of curvature tweaking: motors will start rotating with full speed very quickly almost immediately after the beginning of even the most subtle throttle stick movement up. For the remaining 80-75% of throttle travel there is no difference in RPM. Apparently the same is happening to motors with props attached ... I must confess that I have absolutely no previous experience with RC flying devices, or any RC devices whatsoever. What am I missing here?
