Oh yeah, the trans uses a 9 v battery which is fine for larger planes, but the battery weighs 2 times as much as the camera! It is rated at 8 v so can operate between 7 1/2 to 10 volts. I am trying to get information about connecting it to my flight batteries. I don't know if there needs to be some isolation circuit or if it can be connected direct. If I find out I will leave message here.
