Thanks -- that's reassuring! I appreciate what you wrote about 3
batteries not being a problem, but I would like to know exactly (roughly) how many minutes the thing will go. Is there any posted metric about the Spark transmitter? I found this info on the dji page, but it doesn't say anything about how many minutes the TX will function.
