Hello everybody, i bought geprc tinygo 4k whoop rtf and have some problems.

1) When holding the throttle in one position, the drone itself starts to fly up, or falls down. I've watched a lot of videos where people fly in the house and drones doesn't bounce that much. In general, the drone takes off on its own to the ceiling very quickly when I do not touch the throttle. What to do with it?

2) Drone on two batteries 1s 530mah. Must fly up to 6 min. At the start, my glasses say 7.5 volts (the battery is full). Enough for 1 - 1.5 minutes of slow flight in the room. After that, a warning in glasses (sit down now, low battery). If i do not sit down, the voltage drops to 5.92 and the propellers stop spinning. What to do?

I think something is wrong with pids or motors.
Help please!

If you're new to flying quads then you just need lots of practice to learn some throttle control so you don't keep over compensating with more and less throttle which is what induces the "bouncing" effect. Adding a bit of throttle Expo can help make the centre position of the throttle stick a bit less sensitive to small movements, so you can potentially try that to see if it helps.

You'll be lucky to get 6 mins out of one of those batteries. 3-4 mins is usually the most you can expect on that type of quad with that size of LiPo, and that is with being super gentle and smooth on the throttle. Hovering in one place or bouncing the quad up and down in the air will deplete the battery much faster.

If you let a LiPo cell drop below 3V (so below 6V on a 2S LiPo) you will permanently damage the cell and it will never hold charge as well again after that. Some FC's also require a certain minimum voltage which is why your quad is dropping out of the sky when the voltage is getting that low.

If you are using the factory supplied PIDs and filter settings then it should already be tuned for the best flight time and efficiency.

My TinyGo has NEVER had the batteries last more than 2 1/2 minutes, even brand new out of the bag - I had bought it when I first started the hobby, and loved the advertised '5-6 minutes flight time' - But even in Angle mode I was lucky to get 3 minutes, no matter what the batteries (I have 550mah, and 850mah, both last the same) - The Vista version I imagine would be even harder on batteries
