I'm not a total noob here. That is a band aid that doesn't solve the underlying problem. Something is wrong and I'd like to get it fixed.
I've had this Phantom for a year and it never did this before. Normally when I land the props spin down to the same speed they are at when I first start. Now when I land they keep spinning so fast that it's on the verge of taking off.
In the past I could land and take off as many times as I wanted without having to totally stop the props between each takeoff. Now I can't. I have to stop the props and start them up again if I don't want to tip forward and shred my props.
I'll try calibrating my sticks as Turbazz suggested but I feel like if my sticks weren't calibrated the problem would always be there, not just between take offs. Isn't it weird that everything is normal when I first start the props but then everything goes bonkers after I land. And then back to normal if I stop and restart?
I'm hoping I don't sound too much smart ***...
Your P2 is behaving exactly as it should. Exactly as all the other P2's out there. If you say your bird always allowed you to idle between flights in the past, then maybe your IMU (Inertial Measurement Unit?) or barometer wasn't working as it should,
but maybe now it does.
I can imagine if you feel upset, now your P2 is finally doing what it always was supposed to do, but it really is the only way a Phantom should react after a intentional landing.
If you don't hold the stick down at least 2 seconds the Phantom assumes it's still supposed to hover and start spinning up again. If your P2 is not perfectly balanced, like most, it will tip a bit while it's trying to lift off. This is perfectly normal.
You always have to keep the throttle down until the motors stop. Only THEN the P2 knows it's on the ground.
The only time a Phantom 'knows itself' that it's landed, is when it has landed itself with RTH or Failsafe. It keeps the virtual throttle stick down until it senses it isn't descending for more then 2 seconds, and it shuts down. Even with a battery low auto descent, the motors would still spin after 'landing', because it descended because of low power (the motors spin slower simply because the voltage is dropping), not because of 'down stick'. In that case, the Phantom will keep the motors spinning until they are shut off by you or because the voltage drops even further. It just wouldn't know it had landed at all.
Be happy it is finally working as it should.
I wouldn't trust a Phantom acting the way yours originally did. It could just fall out of the sky during hovering because it could think it is idling on the ground...........
The throttle lock on the new controllers is there to prevent from unintentional take off, directly after landing. I guess DJI wouldn't have added that if it wasn't an intended (or unavoidable) behaviour.
edited a bit for typo's, sorry it was late last night......
