i just got my dr-1 today in the mail today and have already put in a good 8-10mins of flight before the battery died. Ive never flew an rc heli before so it was a bit strange with the controls but after 1 battery im already getting the hang of it, and i love this little thing! only thing i dont like is the way the battery sits in the heli, it likes to slide forward and back and causes the trimming to be a bit of a headache if your trying to get the heli to be 100% stable. but otherwise im having tons of fun with this thing! Who else has the dr-1??
