I have my quad APM2.5 with GPS and sonar flying in stabize mode. I have several flights and I'm happy with both trim and tuning for now. I want to try a second flight mode and I'm thinking about loiter as my first choice. Not sure how this works. I think I'll rise up to about 30' and hold position and then toggle loiter and see what happens. Can I over-ride loiter with the sticks or will the machine disreguard the Tx until I toggle back to stabilize?
Hi there sounds like you have a good stabilize setting there now.I myself would next try altitude hold mode as this has to be working right for loiter too. Get altitude mode tuned and working well and then next you can start trying loiter knowing you wont have to worry about your altitude in loiter.
In Alt hold and loiter you can raise and lower the quad still on the throttle sticks but you will find you need large stick movements on the throttle as there will be a big dead band around the centre point. Also be aware that what position you put the stick in will be there when you switch back to stabalize mode,so if your throttle stick is high in alt hold when you switch to stabalize the quad will climb or drop if the stick is below centre,and this can be quite fast.
As for controlling the quad in loiter you can move the roll pitch and yaw as normal in both alt hold and loiter.
This is my personal experience and has worked for me so far so hope this helps
I have my new quadcopter flying OK in stabilise mode. It has 4 x 300w motors so created a few scares until I lowered Rate P to .09.
I thought I would try out the Loiter mode. Hovering at 1m, flick switch to Loiter mode and the quad headed for the stars at great speed.
Sounds like I should have tried altitude hold mode first.
What should I have done to avoid that scary Loiter experiment?
