By the way...I don't know why the bird in the video makes separate sounds. The chime is normal for a battery being turned on. The sound that you described as a bass sound has never occurred with my craft or batteries. I have no idea what that is. A knock-off battery perhaps?

Anyway, yours is normal as you described it. Now...GO FLY!

Thanks for the information. Motors are in the right place and turning the correct way with the correct props on? It tips over on racing quads if you do not calibrate the props.

Anyone know where I should look as it just tips over backwards before it leaves the ground?

Do all props spin up normally when idling? If you hold the craft and rev the motors...can you tell something strange happening? If you are just asking a hypothetical question...then no...it will not tip over.

I'm not sure what you mean by calibrating the props. If you mean balancing...it helps for smooth AP but should not at all cause your bird to tip over on takeoff. That would more likely be a motor issue. Make sure all props are on tight and aren't broken/bent badly.

The Phantom is a smooth flying bird. It's a great aerial photography craft...not so much racing. (Tho' it will hit 45 mph.)

THANK YOU! The extra beeps happen after the first long (series of beeps) when he first turns it on at 1:30 in that video. But again, whatever because without those extra beeps mine is working so yeah. Maybe knockoff battery/radio?

Double check that you have not set the "MANUAL" (acro) mode in your sticks, using DJI software (connecting Phantom to USB - Computer)

All props spin up normally when idling. My mate held it above his head and I revved it a lot and all seemed good but just a little bit of tipping back.

The attachment is what you must do for the racing quads to get the props spinning evenly when accelerating and a lot of times not as easily as in the video. A lot I have had to plug each ESC into the RX individually and do it that way as in the video.

Naze32 ESC calibration - Baseflight GUI (0 min 45 sec)


It just lifts the front off the ground and tips back with the rear on the ground when taking off.

Thanks

I only recently started looking at it for a mate who wrecked some motors with too long of screws so have not tried the DJI software yet.

He would not have loaded the software to change anything and he has had it flying so should not be in acro. As it just tips back on take off which can be counteracted by pushing the stick forward but you can not fly like that, I just thought I would adjust the joystick trims on the transmitter but there are not any so there must be something in the software to do trim adjustments?

I'll keep working on it.

Thanks

Thanks for this. It has been so long since I've been into the P2 APP that I don't recall if there is anything similar.

It's been quite a bit since I have used the DJI software for the P2 but I am almost certain the transmitter trims/Cal is in that software. I was doing work on a friends that went down in a field and switched 2 motors and ESCs, I know that I had to reset the Calibration of the sticks for straight lift off as well, I would give the software a look and see if that isn't the problem. Can't hurt at this point.

Yeah it has been a long time for me too, but I am sure you are correct.
