Hi FlashHarri
Welcome to the site from a fellow Brit, I live in West Yorkshire, been flying Phantoms for a year or so, small drones and model helicopters before that.
I have a Fully equipped P2 (see my signature) for sale, as I have upgraded now to a P3P.
I've had a lot of fun flying and modifying the P2, its a great bird, like all the Phantoms have been, a little advice however learnt from personal experience:-
Your batteries are probably older ones, 30 or so charges, so I would advise that you always get the P2 back to you and on the ground whilst you still have a minimum of 25% charge remaining (which is something like first bar on battery solid, 2nd bar flashing). I say this because I have found that flying at around 20% charge (on older batteries) and in windy conditions, the surge in current the motors are trying to pull during manoeuvring and hovering sometimes exceeds the intelligent batteries capacity to deliver, so a slow descent from say 15 meters suddenly becomes a fast and difficult to control drop, unless you are very quick and get the bird out of GPS mode into atti mode, where there is a little bit more control and power available. Hear I have found that the DJI ISOD mini (telemetry module) is an absolute must, because one of the readings is the battery Voltage/Percentage Charge, during flight, so you can always get her back with fuel to spare.
Second thing.. forget cheap propellers, the DJI original ones are the best, I've tried cheapies, and carbon Fibre ones, forget it, DJI props every time
Anyway must get back to work, post a reply to me if you want more info..
