[QUOTE="ASD, post: 24045, member: 5327"] Hi there from the UK, Sorry this is just my second post and is so long but I am trying to be as clear and specific as I can. I'm here seeking clarification on the Spark and how it connects to it's controller (RC) / iPhone in order to make a decision on getting DJI Goggles.... My first exposure to drones was via the DRL racing series that was aired in the UK, In the past I have had various RC cars and aeroplanes but the idea of immersive FPV flying is what really drew me and is where I want to be. I was very close to getting a Mavic 12 months ago but lack of supply in the UK at this time resulted in me holding off and looking again now. So my initial plan is to just learn how to fly my Spark with the RC OTG connected to the iPhone and using both line of sight and the iPhone display to find my way around. But ideally I want to add goggles in order to give me the best FPV experience possible.... So... Getting to my understanding (or lack of) of the Spark and it's connection topology. The Spark connects to the RC via WiFi (Inferior but cheaper than Ocusync? - Hence relatively limited range) The RC connects to my iPhone via either WiFi or OTG (Hardwired), OTG seems to be preferred as being more reliable / robust than WiFi for very little extra cost. So my first plan is to get an OTG connection as a start point. If I buy DJI goggles then these connect to my Spark controller using the HDMI port in the goggles to the micro USB in the RC? So a 'hardwired' connection. As far as I can see the DJI goggles has an OSD (On Screen Display) with a reduced functionality version of GO 4 embedded into it, so initially I thought I wont need to worry about an iPhone as I can see what the info I need direct from just the goggles. Question 1: Using DJI goggles.... If I do use an iPhone does the goggles OSD change to all of the parameters I would see via the iPhone display or is it always just the OSD that the goggles are shipped with? So I have to flip up the goggles and check my iPhone for any additional info that the iPhone GO 4 app shows? Question 2: If I need the iPhone (based on the answers to Qu.1) and the RC micro USB connector is now occupied with goggles HDMI connection which means I am now back to the WiFi connection between the iPhone and the RC am I limited by this in any way, either flying range or DJI goggle video drop outs or pixellation? Or does the addition of DJI goggles help this some how. Thanks for reading this Cheers ASD [/QUOTE]
