Default Newbie question

I got my DF earlier this week and think it's an amazing product. I have no RC experience but have been successful in hovering indoors a couple of feet off the ground with the ti off. I've flown outside 4 times, but only with the ti on, as I'm afraid of crashing it from a hight altitude with my limited experience.

Here is my question for anybody that can help. As I stated, I have only flown outside with ti on. Each time I've gotton both green LEDs to light up and only had a light or no breeze. When the DF is high, say above the height of a telephone pole, it will pretty much stay at the same altitude without continual adjustment of the throttle. Below this height however, I must constantly be adjusting the throttle about 1/3 of its travel to keep a constant altitude, or it wants to drop or climb.

If it is about 12 feet or so up, it will start to fall, when I give it enough throttle to keep it up, it will soar up past a telephone pole height. I don't think I'm over shooting the throttle amount needed by adjusting it too fast, as I've tried making very small adjustments.

Is this normal? I just expected the throttle would only need to be adjusted when I wanted to change altitudes. I mentioned my ti settings thinking this may have something to do with the flight characteristics.

Thoughts from anyone?

Kittyhawkone,

Having to continually adjust the throttle is normal when flying with or without ti. It sounds like you are off to a good start with your DF. Have fun!!

Thanks for the input. Now I know I just need to get some more experience under by belt to keep the DF where I want it.

Thanks again.

The reason that the DF falls suddenly is because it has lost lift due to the column of air directly underneath it being evacuated thereby creating a vacuum. What is strange about this is how it happens randomly but it can happen at any height. One way to try to avoid it is to make very small adjustments fore, aft or side to side which will prevent a static hover creating that result. You will always make small adjustments anyway so this should be a rare occurance but it is inherent with this helo.

Thanks for the info on the changes in altitude. I've got about 5 more flights under by belt now and I'm now able to fly more smoothly, including altitude. I've noticed too the dropping doesn't occur like you said if I'm atleast moving laterally a little bit. I'ts a more confident feeling though to hear from an experienced flyer what's happening than to be guessing at what's going on while you are learning.
