Hi all.
I think this may be my first post and I have ended up here after watching pretty much all of thathpiguy's videos on youtube. Apologies if this has been answered before, but I have searched and searched for help for dummies but no luck.
I have a DJI Phantom and Futaba T8J transmitter.
Probably like most people, I have constantly added bits to my setup and the weight has changed constantly of what I am trying to control in the sky. I found that my simple hover was beginning to wobble and jerk around a bit.
So after a bit of advice, someone suggested I downloaded the latest firmware for my gimbal, the Aeroxcraft. I did this and updated it. I have no idea what it was before or what changed, but now my phantom jumped all over the place. It would even vibrate with the motors off while stationary on my desk!! By twiddling around, I found out that this was down to the voltage setting being too high. I took a stab and halved it and the vibrations stopped. But I had no idea if I now had ideal settings or not.
Still with me?
Now someone started telling me about this thing called GAIN. (That was before someone told me you don't need to worry about this nonsense, just get cf props and balance them!!) I have read and read and still don't really know what anyone is talking about regarding gains. The best way I could learn was to look at demos. I saw that with gain too high, the phantom would wobble all over and read that with gains too low, the phantom would be sluggish.
So how do you find out what is best for your own setup? I have been putting it up really high and getting wobbles. So I reduced it... and got wobbles. My mind has been playing tricks with me, but I found one particular video (and read lots of people do the same, but no proof!) where the guy flies his craft and adjusts the gains while flying on his Futaba transmitter. It makes sense that this is the only way to really see if you are benefitting from changing the gains.
So this is where I am... can someone PLEASE tell me how to do this in what should now be apparent as basic a language as possible!
From various videos, I have most of my switches set, but have nothing on those little black switches where most of them are for trim.
I really would appreciate the help as even indoors right now, my phantom seems to have a mind of its own (with fully balanced props I might add).
Thanks guys.
