Ok.....so after action review. I did not really have time to test slower speed or test stall point.....so that's a mute point. I had 3 laps before trying to lower the gear and then that whole issue consumed some time and attention.

Now.....I've had a chance to put the batts on the charger. Out of 8000 mah, only 4800 were put back in each pack. I could understand if lvc happened and had to put in 6000+, but 4800 is barely 60%. Its possible the batts were getting warm so the voltages sagged lower then it should have. I'm sure the biela 20x14 prop didn't help things either as some people have said they are kinda inefficient. So that amp hungry prop and warm batts didn't do me any favors. I may try a mejlik 20x12 as I've heard they are more efficient.
Great job on the LVC challenge. I've lost two big planes to LVC.
Running the lipos at next to full throttle is definitely a problem. Generally, 15 seconds of full throttle is recommended, then backing off to 3/4 or 1/2 for a short period of time.
You should call Castle. I would love to know their opinion on what happened.
Again, Congrats on the maiden!
