I just experienced a perfect upgrade.
I started RC - iPad - Aircraft ... waited for about 5 minutes and the only upgrade that was required was the Aircraft. The warning directed me to the home screen to download upgrade.
Went to home screen and downloaded the update. Then it directed me to connect my iPad to the Aircraft. I did and started the upgrade. It took about 8 minutes and completed to 100% and disappeared. During the process some camera movement and some lights flashing. At 95% it even cycled the craft off then back on.
I turned everything off and back on RC - iPad - Aircraft. Now it told me the RC needed to be upgraded. I downloaded the update and started the upgrade. It also finished to 100% and disappeared. This took about 6 minutes and had normal RC beeping noise during update.
I cycled everything off and back on and all is well. Piece of cake!!!
I will fly it tomorrow!
