transmission

In Sport mode I can fly the spark pretty fast. But in GPS mode.. I normally get about 6-7 mph. Seems very slow... Spec says should be about 12 mph.. What are you guys getting ? Also.. Since they did away with the OTG cable... The image transmission seems to get worse. I get Weak Image...

Hey, Just got my Spark and so far so good except for the fact that my Live Video Feed (on the DJI GO4 app) seems to cut out after about 100m... Is this normal? How can I try fix this? Also, on a completely separate note: is there any obvious reason that everyone else's video footage seems to...
