Okay troops, here is my story. I have just received a new Phantom P3P from B&H due to a firmware upgrade problem that DJI in CA couldn’t remedy. They said return the defective unit to the dealer, which I did. The exchange through B&H was a breeze. So now I have the new bird with these specs: App # 1.2.0 and Firm # 1.1.9. RC #GL 300A, (the returned RC was the “B” model.) Folks on this forum have said to NOT to upgrade if the aircraft is flying okay. Recently we’re hearing that if we do NOT upgrade to DJI “GO” , etc. and we have a problem, we will not be covered by the warrantee. To be honest, I am very apprehensive to “upgrade” after my terrible experience the first time around. Yes, I have done a search on this forum. Yes, I follow the upgrade instructions to the letter. Sorry, but this noob needs some expert guidance here. Thanks !
