I took my H with the updated firmware out this afternoon as the weather here (Southwestern Ontario) was nice (for February) - 10°C and sunny with only 9-10km wind. After doing a Compass recal at the launch site, the H seemed to be stuck on "acquiring GPS" for several minutes. So I turned the H off then back on again and it was good to go then with 20 sats on both the ST16 and the H. Right away I noticed a smoother response to the sticks. the hover was dead on inspite of the 9-10k breeze. I tested the yaw, roll, pitch, alt all in pilot/rabbit mode and it responded great in all but seemed "smoother" than before this update. I had changed my alt limit to 300m in the GUI, so decided to test if would go beyond the previous 121m (400') limit. No problem, it climbed to 171m (561') and would go higher but I almost lost sight of it so held it there for a minute or so. Even though the battery was not 100% charged to begin with as I had used it to do the upgrade 2 days ago, I flew aggressively for 16 minutes before getting the first low bat warning. The landing was very precise and smooth and after some manouvering, I landed on my 32" hexagonal launch pad almost dead centre. IMO this was a noticeable improvement in flight characteristics compared to the previous version.
