I was the guy who made FBW-B alt limit mode, please remember that ALT_HOLD_FBWCM is in centimetres, NOT meters! When I made that mode there was no Cruise mode, so I can't say anything about it.
I've recently tried to setup APM for my new flying wing and discovered that it is not safe to fly in other than Manual modes =( The reason is servo throws for most flying wings must be limited, but APM limits them only in Manual, in all other modes…
"Я думаю так будет проще =) В режиме стабилизации:
1)сервы пытаются выровнять самолет в более-менее адекватных количествах и точно в верных направлениях.
2)тяну ручку элеватора на себя до упора - в ручном режиме сервы отрабатывают идеально, в режиме…"
"Ok, decreased P values for Servo and Nav parameters gradually - nothing changed. Then I've put 0.050 value in all of them - still no results. And - yes I didn't forget to hit 'Write Params' button. Any ideas?"
"I'm having the same problem as Istvan - too much throws in STAB mode. Tried to change RC MAX and MIN values. Got really weird results if I change the values too much - elevons turning to the other side(like reversed). What should I change?"
