Just registered...bought a 450 clone a couple years ago and didn't have a good experience. Just purchased and built a align 250 and am starting from scratch. Wish me luck
I will say this, the 250 is going to be harder to control. It's much more twitchy than the 450's. Bit I'd you can get the gyro setup correctly, it will help. And as always if you get stuck, just ask.
After some set up snafu's things are going well. Thank you for your suggestions, I had put in lots of simulator hours prior to purchasing my 250...and had been flying a blade nano...Pleased to report I have yet to put the 250 in the grass
