When I took my ONAGOfly out for the initial flight, it was a disaster. Later I found it was no fault of the drone, the iPhone I was using was not compatible. I since have upgraded to a newer iPhone so now I will put it through a test and update my review after the flight. I do find the 5 star reviews to be a bit suspect. If you read them closely, the wording is very similar to wording in an instruction manual of an item you purchased from China. I have hopes that those 5 star reviews are not false claims. I will find out for myself very shortly and provide you with the results.
