Attempted a 4.5 mile mountain proximity flight with my Foamaroo. Using TLRS control system with the Rx antennas out on the wings 18 inches from the GoPro camera and experienced lots and lots of failsafes, even with 1 or 2W of power. I edited out most of them, but every time you see the nose come up, it's a failsafe. Very frustrating.
Can also see from the beginning that launching the low wing version of the Foamaroo with 8000mAh and GoPro on board is challenging.
