I cannot help but notice that all the 'tweaks' to up the power from CE to FCC levels seem to end up with various posts where problems are encountered. This reminds me of early days of Orange Gyros where Fw updates were bandied about and failures were found by odd people - have to include myself there ... 2 failed out of 7 units when re-flashed. Similar with various Rc Transmitters and the FW ... people ending up with 'bricked' Tx's and no fallback. I expect that my P3S will arrive from China with FCC level but as soon as the GPS location fires up - I expect it to switch to CE region. Not something I want to happen ... but reading through threads on this site - I don't think I will be delving into the model via FTP ! I have to admit that scrolling through page after page of amendments and notes has been nothing short of frustrating. It also seems to contradict with guys I fly with who say they have xxxx results ... didn't have to do FTP .... etc. etc. I am still waiting my P3S to arrive ... I'm buying up bits and pieces while waiting to add to it ... and reading as much as I can before it arrives to provide a grounding for me to build on. Youtube videos watched and scrutinised for info ... trouble there is so often the video skiddadles of into realms unrelated !!
