Hi Guys, I have been flying my P1.1.1 for almost 3 years now without it ever being connected to a computer. It has been perfect and any crashes have all been my fault. Following all the advice and tips on this site I upgraded to 5200 Multistar batteries to carry a Ricoh GR camera for better quality photographs. Since these changes to the craft it has become quite a handful in the air, very slow to respond to the sticks but otherwise manageable. I have now had 3 bad crashes after take off and hovering, when I move to fly to the left the craft accelerates full throttle sideways and cannot be stopped! The last crash ended up in a river, I have dried it out completely with advice from you guys and everything seems be ready to go again, the only difference I have noticed is that when I throttle up, the motors stay on full and do not return to idle when I return to idle position. This is without the props on. I do not want to fly again and ruin another camera so it is now time to connect it to a computer to find out what is going on.I only have access to Mac computers and cannot connect. Any suggestions?
