As a cautious newbie I spent a week reading up on all the good advice I could find. The Summary Guide PDf is invaluable and I switched mine to NAZA-M and enabled IOC before I even flew it (I have a BIG sticker reminding me to check S1/S2 are UP though). Lots of advice to learn to fly in ATTI mode, because at some point you may well need it. Being able to fly it without relying on GPS, RTH or HL makes SO much sense. Still on my learning curve with it, but getting much better. I've seen some advice today that I should learn to fly it in MANUAL mode - I don't get that advice, it seems wrong to me. If I have it right that will take away any stabilisation, render the IMU and compass pointless ? Sounds to me like that's something only VERY experienced pilots should do - am I right ?
