Hi Doug,
do you have a picture of the position of the 10s pack ? So you are using the heavy APC prop with about 100 g; if using the very light Falcon 21x13,5 the 10s pack needs to be more forward.
I am planing to modify the battery plywood tray. So I will make it longer to have more possibility of moving the 10s pack.
Regards
