Continuing the discussion from Smart controller lag:
Update from previous topic,
The lag on my smart control got so bad (10 seconds) I made a few calls, leading to me taking out the Micro sd card in the controller (64gb sandisk extreme pro).
So far so good, lots of flying, approx 10 hours in last 2 weeks, no lag in menorca and back in the UK.
So a partial solution for the moment, I will be trying the card back in at some point though.
When you say with the SD card. Is the SC utilising the SD card whilst youre up in the air?
I need to do some flying to give this a test. Only had a a couple of short flights and not noticed the lag. I do have the SD card inserted but Im pretty sure its not doing anything but sitting there 
@sunstone not really sure what it was or wasn’t doing while I was flying,
No-one else seems to have had a problem that i can see either.
All I know is with it in as the flights progressed lag got worse, without card in no lag at all.
Certainly interesting @lee . Im due to get some decent flying time with mine this weekend, so I’ll keep my eye out for lag issues.
Lets hope yours has been sorted!
