WARNING:
Never lend anyone your copter.
I borrowed James Helliwell's DJI 550 to try and sort out the gimbal so it could be moved from the transmitter. I thought I'd give it a bit of a try in the garden - awesomely stable (naza gps) until I smashed it into my tree (it's got a tree protection order on it, so it's big!)
Smashing 3 blades and the landing gear.
I brought it inside and ordered some new blades and went back to work on the gimbal. I got it set up eventually so it would be adjusted and would still self level and work properly. Awesome. Then I moved the sticks which caused it to start up and repeatedly smack my monitor until I could shut it down.
I gave James the copter back this past weekend - with a load of blades. He took off - and immediately smashed it up because I'd accidentally swapped the channels round on the reciever. So I not only smashed it in person but also by proxy.
I AM AWESOME
I think I will get one to practice with
