Hi,
I was wondering if someone could please have a look at a couple of flight logs for me? I’ve had my spark fly off a couple of times and I’m unsure why this is happening.
I’ve managed to regain control and fly my spark back. Is it something that i might be doing wrong? It looks like a speed/yaw error.

Thank you 
Was there anything metallic near your Spark between the time you powered it on and took off?
In your first log, it looks like you took off from a concrete driveway. Many concrete structures contain rebar.
Hi msinger,
Yes i took off from the car park at work.
That was likely the issue then. In order to prevent a situation like this, make sure you’re doing these checks before taking off:

thanks for the link. I will keep my eye out for that the next time i go out for a fly.
