I fit in a 7 minute flight this morning, still w/o the VDL, it should be here today according to USPS tracking.
I was happy to get 7 minutes flying on a Thunder Power 3300 45C 3S and I still had 30% left, total time on was over 9 minutes.
I was lucky to get a flight in between heavy rain showers.
I was pretty heavy on the controls and did some fast ascends and descents, this always makes the 450 shake a bit, there is only one time on a descent I saw the turbulent flight come through the gimbal. I have to analyze a bit more.
GPS mode held very well with the new FW (all the latest on my rig) as of 7/11/13.
