I have a new smoke pump that worked fine for one 29oz tank. On second flight I used it smoke ran about a minute then stopped. When I power up jet on the ground the light is red for a little bit then turns solid green. When I move my slider to +100 nothing happens. I am using a 2s Lipo that powers the pump and my unilights. There is a red V4 sticker on the back of the pump. Any suggestions?
