You didn't notice these errors before actually taking off?  8 seconds int the proccess you received Max Altitude Approached. Wait for the GPS satellite signal recovery before ascend.

Why did you switch to Sport mode before you had a GPS lock?

There are some definite pilot errors here, you took off without gps , your RC would be screaming a warning not to take off and that you were in Atti mode, once you took off in this mode you should have been at least able to control your AC , I would surmise you didn't have any experience.

It looks to me you had compass problems on the ground before you took off, you could have been launching from rebar concrete or metal objects near by.

This would have effected your gps and caused deep conflict between what you might have been commanding your AC to do, and actually what it was doing, your aircraft eventually landed when it lost signal for 15 seconds.

You never mentioned if you found it and if it was ok, if you did I recommend you read this thread.

There are some definite pilot errors here...that's an understatement.

No i didn't find it.. it's lost. If i would find it i wouldn't be opening this thread. I took of and waited for a gps signal, when it caught the signal and showed green then i flew further on a sport mode, and then it started to do strange things, and the problem was not near the ground when i started flying, but when i flew up and then the problem started at it lost the controll. The compass and everything on the ground and near was fine.

You took off with zero satellites....tough lesson learned I guess.

Your total inexperience really shows in what you write.

You were 80 feet in the air before you received enough satellites. You don't take off and wait for gps you get gps then take off. You got a warning at 14 feet not to go any higher, yet you continued .

Your spark landed 250 feet away from you unless you were not able to see it or its direction , you should have been able to find it.

Can you tell me what you done to check compass on the ground.

I believe that there might be a language barrier between us and the OP.  Yes its very unfortunate that @rachas has possibly lost his Spark, but hopefully he fully understands what he did wrong.

Yes. I totally agree. Issues and post like this give the rest of us a bad name when we have a legitimate fly-away situation. Which years of piloting and I can say has never happened to me once.
