im a beginner still practicing my flying with phantom 2. i bought it with the new gimbal but dont want to install gimbal yet. Just want to become proficient at flying first. but i realize i do need to confirm that gimbal is working. my question is can i go ahead and hook up the gimbal without hooking up go pro that i dont even have yet.. power it all up to confirm gimbal works... i know im not supposed to power up video transmitter without antenna connected but can i safely hook up the gimbal just for a test , then take it back off while im still practicing flying? thanks for your time.
