Today I took my precious P2V for a test flight over the capitol of Estonia, Tallinn with the new 3.0 firmware including no-fly limits.
This town has a city airport so I was worried that the limits would ruin my summer plans for great areal filming of this beautiful city.
According to my calculations the limits set by the no-fly restrictions would be around 60-70m. This are my conclusions.
1. I could actually go up to 190m (Not 60-70m) before it started to descent slowly and the FPV screen said GOING HOME.
2. During the descent I could control the Phantom in every way except gaining altitude.
3. At about 65m the descent stopped and everything was normal. The GOING HOME message went off.
4. I could then make another altitude run with similar result as before.
5. Seems that the altitude is counting from 0m at take of not altitude over sea level. (Great relief for those on a hill)
6. Generally the Phantom behaved as expected and I did not find any anomalies in the flying at all exempt for the forced descent.
Conclussions
The No-Fly limitation worked kind of gently. It´s probably a good idea to safely establish your max heigh before goin over high structures in case it start to do a forced descent and you need to fly home. Om the other hand you can make a altitude run upp to some no-fly altitude +150m and then it will take a minute or two before it is down to the no-fly limit again.
I think it totally sucks like hell that DJI is crippling of our loved Phantoms. Customer satisfaction is obviously not in their first interest.
This said it kind of works gently and did not mess my up flight totally.
