In its stock form from the factory the iflight Helion 10 has a 5volt aux power output that does put out 5volts. Unfortunately, this is not enough power to turn on a GoPro HERO 10 BONES.
In order to run a GoPro hero 10 bones you need to do this mod OR you can run an auxiliary power supply from the balance cable I choose to do a hardwire fix, because I do not want to mess around with the balance lead every time I change the battery.
I hope you find this video helpful and happy flying.
