Since I got my 700, I've been flying it most of the time. My 550 gets about one flight for every 10 flights with the 700. The 450? Well, I did not enjoy it anymore so I sold it.
What size helis do you guys have and which one is your favorite to fly?
I have the 450 Pro DFC, 500e flybarred, and 600 Pro DFC. I very much enjoy flying them all. I'm still working on the settings for the 600 but all 3 are fun to me.
