Hello, if I say I consider myself a noob then I thought maybe my post stands a better chance of not being labelled stupid. Until recently I believed the M2P itself had a GPS module onboard, on finding out it was the smartphone or cellular tablet it had me wondering how it manages to fix a RTH point? I have just got an 8th gen iPad and intend to use it mounted on the RC can someone please advise me what if any the drawbacks will be by using a non cellular device. Thank you.
